Paleotempestology

Last updated

Paleotempestology is the study of past tropical cyclone activity by means of geological proxies as well as historical documentary records. The term was coined by American meteorologist Kerry Emanuel.

Contents

The usual approach in paleotempestology is the identification of deposits left by storms. Most commonly, these are overwash deposits in waterbodies close to the coast; other means are oxygen isotope ratio variations caused by tropical cyclone rainfall in trees or speleothems (cave deposits), and identifying beach ridges kicked up by storm waves. The occurrence rate of tropical cyclones can then be inferred from these deposits and sometimes also their intensity – typically the stronger events are the most easily recognizable ones –, by comparing them to deposits left by historical events.

Paleotempestological research has shown that in the Coast of the Gulf of Mexico and in Australia, the occurrence rate of intense tropical cyclones is about once every few centuries, and there are long-term variations in occurrence which are caused, for example, by shifts in their paths. Common problems in paleotempestology are confounding factors such as tsunami-generated deposits, and the fact that only some parts of the world have been investigated.

Definition and rationale

Paleotempestology is the estimation of tropical cyclone activity with the help of proxy data. The name was coined by Kerry Emanuel of the Massachusetts Institute of Technology; [1] the field has seen increased activity since the 1990s [2] and studies were first carried out in the United States of America [3] on the East Coast. [4]

The realisation that one cannot rely solely on historical records to infer past storm activity was a major driving force for the development of paleotempestology. [5] The historical record in many places is too short (one century at most) to properly determine the hazard produced by tropical cyclones, especially the rare very intense ones [1] which at times are undersampled by historical records; [6] in the United States, for example, only about 150 years of record are available, and only a small number of hurricanes classified as category 4 or 5 – the most destructive ones on the Saffir-Simpson scale – have come ashore, making it difficult to estimate the hazard level. [7] Such records may also not be representative for future weather patterns. [8] [9]

Information about past tropical cyclone occurrences can be used to constrain how their occurrences may change in the future, or about how they respond to large-scale climate modes, such as sea surface temperature changes. [1] In general, the origin and behaviour of tropical cyclone systems is poorly understood, [10] and there is concern that human-caused global warming will increase the intensity of tropical cyclones and the frequency of strong events by increasing sea surface temperatures. [11] [8]

Techniques

In general, paleotempestology is a complex field of science that overlaps with other disciplines like climatology and coastal geomorphology. [12] A number of techniques have been used to estimate the past hazards from tropical cyclones. [7] Many of these techniques have also been applied to studying extratropical storms, although research on this field is less advanced than on tropical cyclones. [4]

Overwash deposits

Overwash deposits in atolls, coastal lakes, marshes or reef flats are the most important paleoclimatological evidence of tropical cyclone strikes. When storms hit these areas, currents and waves can overtop barriers, erode these and other beach structures, and lay down deposits in the water bodies behind barriers. [13] [2] [14] Isolated breaches and especially widespread overtopping of coastal barriers during storms can generate fan-like, layered deposits behind the barrier. Individual layers can be correlated to particular storms in favourable circumstances; in addition they are often separated by a clear boundary from earlier sediments. [11] Such deposits have been observed in North Carolina after Hurricane Isabel in 2003, for example. [15] The intensity [3] and impacts of the tropical cyclone can also be inferred from overwash deposits [16] by comparing the deposits to these formed by known storms [3] and analyzing their lithology (their physical characteristics). [17] Additionally, thicker sediment layers usually correspond to stronger storm systems. [3] This procedure is not always clear-cut however. [18]

Several techniques have been applied to separate out storm overwash deposits from other sediments:

Generally, sites suitable for obtaining paleotempestology records are not found along the entire length of the coastline, [19] and depending on the properties of the site such as vegetation cover, [27] they might only track storms approaching from a certain direction. [17] Prerequisites for successful correlation of overwash deposits to tropical cyclones are: [28]

Dating and intensity determination

Various dating techniques can then be used to produce a chronology of tropical cyclone strikes at a given location and thus a recurrence rate; [2] [14] for example, at Lake Shelby in Alabama a return period of once every 318 years was determined. The storms in the Lake Shelby record have windspeeds of over 190 kilometres per hour (120 mph) [30] as Hurricane Ivan which in 2004 made landfall in the region at that intensity did not leave a deposit. [31] Based on geological considerations the minimum windspeed of storms recorded there might be 230 kilometres per hour (143 mph). [30]

For dating purposes radiometric dating procedures involving carbon-14, cesium-137, and lead-210 are most commonly used, often in combination. [25] Uranium series dating, [32] optically stimulated luminescence, [33] and correlations to human land use can also be used in some places. [20]

Beach ridges

Beach ridges and cheniers [2] form when storm surges, storm waves or tides deposit debris in ridges, with one ridge typically corresponding to one storm. [34] Ridges can be formed by coral rubble where coral reefs lie at the coast, [35] and can contain complicated layer structures, [36] shells, [37] pumice, [38] and gravel. [39] A known example is the ridge that Cyclone Bebe generated on Funafuti atoll in 1971. [40]

Beach ridges are common on the deltaic shores of China, and are indicative of increased typhoon activity. [3] They have also been found on the Australian coast facing the Great Barrier Reef and are formed from reworked corals. The height of each ridge appears to correlate with the intensity of the storm that produced it, and thus the intensity of the forming storm can be inferred by numerical modelling and comparison to known storms [41] and known storm surges. [42] Ridges tend to be older the farther inland they are; [43] they can also be dated through optically stimulated luminescence [44] and radiocarbon dating. [38] In addition, no tsunami-generated beach ridges have been observed, and tsunamis are important confounding factors in paleotempestology. [45]

Wind-driven erosion or accumulation can alter the elevation of such ridges, and, in addition, the same ridge can be formed by more than one storm event [46] as has been observed in Australia. [47] Beach ridges can also shift around through non-storm processes after their formation [43] and can form through non-tropical cyclone processes. [48] Sedimentary texture can be used to infer the origin of a ridge from storm surges. [49]

Isotope ratios

Precipitation in tropical cyclones has a characteristic isotope composition with a depletion of heavy oxygen isotopes; carbon and nitrogen isotope data have also been used to infer tropical cyclone activity. [50] Corals can store oxygen isotope ratios which in turn reflect water temperatures, precipitation and evaporation; [51] these in turn can be related to tropical cyclone activity. [52] Fish otoliths and bivalves can also store such records, [53] as can trees where the oxygen isotope ratios of precipitation are reflected in the cellulose of trees, and can be inferred with the help of tree rings. [50] However, confounding factors like natural variation and soil properties also influence oxygen isotope ratios of tree cellulose. For these reasons, only the frequency of storms can be reliably estimated from tree ring isotopic records, not their intensity. [23]

Speleothems, deposits formed in caves through the dissolution and redeposition of dolomite and limestone, can store isotope signatures associated with tropical cyclones, especially in fast growing speleothems, areas with thin soils and speleothems which have undergone little alteration. Such deposits have a high temporal resolution, and are also protected from many confounding factors [23] although the extraction of annual layers has become possible only recently, with a two-week resolution (two separate layers correlated to two hurricanes that struck two weeks apart) achieved in one case. [54] However, the suitability of speleothems depends on the characteristics of the cave they are found in; caves that flood frequently may have their speleothems eroded or otherwise damaged, for example, making them less suitable for paleotempestology research. [55] Caves where speleothems form mainly during the offseason are also likely to miss tropical cyclones. [56] Very old records can be obtained from oxygen isotope ratios in rocks. [57]

Other techniques

Historical documents such as county gazettes in China, diaries, logbooks of travellers, official histories and old newspapers can contain information on tropical cyclones. [58] In China such records go back over a millennium, [3] while elsewhere it is usually confined to the last 130 years. [59] Such historical records however are often ambiguous or unclear. [1] The frequency of shipwrecks has been used to infer past tropical cyclone occurrence, [17] such as has been done with a database of shipwrecks that the Spaniards suffered in the Caribbean. [60]

Aside from oxygen isotope ratios, [50] tree rings can also record information on storm-caused plant damage or vegetation changes, [61] such as thin tree rings due to storm-induced damage to a tree canopy, and saltwater intrusion and the resulting slowdown in tree growth. The term "dendrotempestology" is used in this context. [62] [60] [63] Speleothems can also store trace elements which can signal tropical cyclone activity [64] and mud layers formed by storm-induced cave flooding. [55] Droughts on the other hand can cause groundwater levels to drop enough that subsequent storms cannot induce flooding and thus fail to leave a record, as has been noted in Yucatan. [65]

Other techniques:

Timespans

A database of tropical cyclones going back to 6,000 BC has been compiled for the western North Atlantic Ocean. [81] In the Gulf of Mexico, records go back five millennia [14] but only a few typhoon [lower-alpha 1] records go back 5,000–6,000 years. [32] In general, tropical cyclone records do not go farther back than 5,000–6,000 years ago when the Holocene sea level rise levelled off; tropical cyclone deposits formed during sea level lowstands likely were reworked during sea level rise. Only tentative evidence exists of deposits from the last interglacial. [83] Tempestite deposits [84] and oxygen isotope ratios in much older rocks have also been used to infer the existence of tropical cyclone activity [57] as far back as the Jurassic. [84]

Results

Paleotempestological information has been used by the insurance industry in risk analysis [85] in order to set insurance rates. [63] The industry has also funded paleotempestological research. [86] Paleotempestology information is further of interest to archeologists, ecologists, and forest and water resource managers. [87]

Recurrence rates

The recurrence rate, the time gap between storms, is an important metric used to estimate tropical cyclone risk, and it can be determined by paleotempestological research. In the Gulf of Mexico, catastrophic hurricane strikes at given locations occur once about every 350 years in the last 3,800 years [14] or about 0.48%–0.39% annual frequency at any given site, [88] with a recurrence rate of 300 years or 0.33% annual probability at sites in the Caribbean and Gulf of Mexico; [89] category 3 or more storms occur at a rate of 3.9–0.1 category 3 or more storms per century in the northern Gulf of Mexico. [90] Elsewhere, tropical cyclones with intensities of category 4 or more occur about every 350 years in the Pearl River Delta (China), [91] one storm every 100–150 years at Funafuti and a similar rate in French Polynesia, [74] one category 3 or stronger every 471 years in St. Catherines Island (Georgia), [92] 0.3% each year for an intense storm in eastern Hainan, [93] one storm every 140–180 years in Nicaragua, [94] one intense storm every 200–300 years in the Great Barrier Reef [41] – formerly their recurrence rate was estimated to be one strong event every few millennia [95] – and one storm of category 2–4 intensity [96] every 190–270 years at Shark Bay in Western Australia. [97] Steady rates have been found for the Gulf of Mexico and the Coral Sea [98] for timespans of several millennia. [88]

However, it has also been found that the occurrence rates of tropical cyclone measured with instrumental data over historical time can be significantly different from the actual occurrent rate. In the past, tropical cyclones were far more frequent in the Great Barrier Reef [41] and the northern Gulf of Mexico than today; [99] in Apalachee Bay, strong storms occur every 40 years, not every 400 years as documented historically. [100] Serious storms in New York occurred twice in 300 years [101] not once every millennium or less. [102] In general, the area of Australia appears to be unusually inactive in recent times by the standards of the past 550–1500 years, [103] and the historical record underestimates the incidence of strong storms in Northeastern Australia. [104]

Long term fluctuations

Long-term variations of tropical cyclone activity have also been found. The Gulf of Mexico saw increased activity between 3,800–1,000 years ago with a fivefold increase of category 4–5 hurricane activity, [105] and activity at St. Catherines Island and Wassaw Island was also higher between 2,000 and 1,100 years ago. [106] This appears to be a stage of increased tropical cyclone activity spanning the region from New York to Puerto Rico, [107] while the last 1,000 years have been inactive both there and in the Gulf Coast. [108] Before 1400 AD, the Caribbean and the Gulf of Mexico were active while the East Coast of the United States was inactive, followed by a reversal that lasted until 1675 AD; [109] in an alternative interpretation, the US Atlantic coast and the Caribbean saw low activity between 950 AD and 1700 with a sudden increase around 1700. [32] Such fluctuations appear to mainly concern strong tropical cyclone systems, at least in the Atlantic; weaker systems have a more steady pattern of activity. [110] Rapid fluctuations over short timespans have also been observed. [87]

In the Atlantic Ocean, the so-called "Bermuda High" hypothesis stipulates that changes in the position of this anticyclone can cause storm paths to alternate between landfalls on the East Coast and the Gulf Coast [11] [111] but also Nicaragua. [112] Paleotempestological data support this theory [113] although additional findings on Long Island and Puerto Rico have demonstrated that storm frequency is more complex [108] as active periods appear to correlate between the three sites. [114] A southward shift of the High has been inferred to have occurred 3,000 [115] –1,000 years ago, [116] and has been linked with the "hurricane hyperactivity" period in the Gulf of Mexico between 3,400–1,000 years ago. [117] Furthermore, a tendency to a more northerly storm track may be associated with a strong North Atlantic Oscillation [118] while the Neoglacial cooling is associated with a southward shift. [117] Atmospheric conditions favourable for tropical cyclone activity in the "main development region" [lower-alpha 2] of the Atlantic are correlated to unfavourable conditions along the East Coast. [120] In West Asia, high activity in the South China Sea coincides with low activity in Japan and vice versa. [121] [122]

Role of climate modes

The influence of natural trends on tropical cyclone activity has been recognized in paleotempestology records, such as a correlation between Atlantic hurricane tracks [123] and activity with the status of the ITCZ; [124] [125] [126] position of the Loop Current (for Gulf of Mexico hurricanes); [88] North Atlantic Oscillation; sea surface temperatures [127] and the strength of the West African Monsoon; [128] and Australian cyclone activity and the Pacific Decadal Oscillation. [129] Increased insolation – either from solar activity [130] or from orbital variations – have been found to be detrimental to tropical cyclone activity in some regions. [131] In the first millennium AD, warmer sea surface temperatures in the Atlantic as well as more restricted anomalies may be responsible for stronger regional hurricane activity. [132]

Among the known climate modes that influence tropical cyclone activity in paleotempestological records are ENSO phase variations, which influence tropical cyclone activity in Australia and the Atlantic, [133] but also their path as has been noted for typhoons. [134] [135] [136] More general global correlations have been found, such as a negative correlation between tropical cyclone activity in Japan and the North Atlantic [131] and correlation between the Atlantic and Australia on the one hand [137] and between Australia and French Polynesia on the other hand. [138]

Influence of long-term temperature variations

The effect of general climate variations have also been found. Hurricane [139] and typhoon tracks tend to shift north (e.g. Amur Bay) during warm periods and south (e.g. South China) during cold periods, [140] patterns that might be mediated by shifts in the subtropical anticyclones. [108] These patterns (northward shift with warming) has been observed as a consequence of man-made global warming and the end of the Little Ice Age [139] but also after volcanic eruptions (southward shift with cooling); [141] some volcanic eruptions have been linked to decreased hurricane activity, although this observation is not universal. [142]

During the 1350 to present interval in the Little Ice Age, there were more but weaker storms in the Gulf of Mexico [143] while hurricane activity did not decrease in western Long Island. [114] Increased hurricane activity during the last 300 years in the Caribbean may also correlate to the Little Ice Age. [144]

The response of tropical cyclones to future global warming is of great interest. The Holocene Climatic Optimum did not induce increased tropical cyclone strikes in Queensland and phases of higher hurricane activity on the Gulf Coast are not associated with global warming; [32] however warming has been correlated with typhoon activity in the Gulf of Thailand [145] and marine warming with typhoon activity in the South China Sea, [146] increased hurricane activity in Belize (which increased during the Medieval Warm Period) [147] and during the Mesozoic when carbon dioxide caused warming episodes [84] such as the Toarcian anoxic event. [148]

After-effects of tropical cyclones

A correlation between hurricane strikes and subsequent wildfire activity [149] and vegetation changes has been noted in the Alabaman [150] and Cuban paleotempestological record. [151] In St. Catherines Island, cultural activity ceased at the time of increased storm activity, [152] and both Taino settlement of the Bahamas [89] and Polynesian expansion across the Pacific may have been correlated to decreased tropical cyclone activity. [138] Tropical cyclone induced alteration in oxygen isotope ratios may mask isotope ratio variations caused by other climate phenomena, which may thus be misinterpreted. [153]

On the other hand, the Classic Maya collapse may coincide with, and have been caused by, a decrease in tropical cyclone activity, [154] because tropical cyclones are more important for preventing droughts in the southeastern US. [155]

Problems

Paleotempestological reconstructions are subject to a number of limitations, [24] including the presence of sites suited for the obtainment of paleotempestological records, [19] changes in the hydrological properties of the site due to e.g. sea level rise [24] which increases the sensitivity to weaker storms [156] and "false positives" caused by for example non-tropical cyclone-related floods, sediment winnowing, wind-driven transport, tides, tsunamis, [24] bioturbation [17] and non-tropical storms such as nor'easters [157] or winter storm, the latter of which however usually result in lower surges. [158] In particular, tsunamis are a problem for paleotempestological studies in the Indian and Pacific Ocean; [159] one technique that has been used to differentiate the two is the identification of traces of runoff which occurs during storms but not during tsunamis. [160]

Not all of the world has been investigated with paleotempestological methods; among the places thus researched are Belize, the Carolinas of North America, northern coasts of the Gulf of Mexico, the northeastern United States, [19] (in a lesser measure) the South Pacific islands and tropical Australia. [59] Conversely China, [161] Cuba, Florida, Hispaniola, Honduras, the Lesser Antilles and North America north of Canada are poorly researched. The presence of research institutions active in paleotempestology and suitable sites for paleotempestological research and tropical cyclone landfalls may influence whether a given location is researched or not. [19] In the Atlantic Ocean, research has been concentrated on regions where hurricanes are common rather than more marginal areas. [162]

Paleotempestology records mostly record activity during the Holocene [161] and tend to record mainly catastrophic storms as these are the ones most likely to leave evidence. [6] In addition, as of 2017 there has been little effort in making comprehensive databases of paleotempestological data or in attempting regional reconstructions from local results. [162]

Also, paleotempestological records, especially overwash records in marshes, are often grossly incomplete with questionable geochronology. Deposition mechanism are poorly documented, and it's often not clear how to identify storm deposits. [163] The magnitude of overwash deposits is fundamentally a function of storm surge height, which, however, is not a function of storm intensity. [72] Overwash deposits are regulated by the height of the overwashed barrier and there is no expectation that it will remain stable over time; [164] tropical cyclones themselves have been observed eroding such barriers [165] and such barrier height decreases (e.g. through storm erosion or sea level rise) may induce a spurious increase of tropical cyclone deposits over time. [166] Successive overwash deposits can be difficult to distinguish, and they are easily eroded by subsequent storms. [167] Storm deposits can vary strongly even a short distance from the landfall point, [168] even over few tens of metres, [169] and changes in tropical cyclone activity recorded at one site might simply reflect the stochastic nature of tropical cyclone landfalls. [120]

Application to non-tropical storms

Paleotempestological research has been mostly carried out in low-latitude regions [170] but research in past storm activity has been conducted in the British Isles, France and the Mediterranean. [171] Increases in storm activity on the European Atlantic coast have been noted AD 1350–1650, AD 250–850, AD 950–550, 1550–1350 BC, 3550–3150 BC, and 5750–5150 BC. [172] In southern France, a recurrence rate of 0.2% per year of catastrophic storms has been inferred for the last 2,000 years. [173]

Storm records indicate increased storm activity during colder periods such as the Little Ice Age, Medieval Dark Age and Iron Age Cold Epoch. [174] During cold periods, increased temperature gradients between the polar and low-latitude regions increase baroclinic storm activity. Changes in the North Atlantic Oscillation may also play a role. [173]

Notes

  1. Typhoons are tropical cyclones in the West Pacific. [82]
  2. The "main development region" is an area between 10° and 20° northern latitude and between 20° and 60° western longitude in the Atlantic where numerous hurricanes form. [119]

Subtropical cyclone Meteorological phenomenon

A subtropical cyclone is a weather system that has some characteristics of a tropical and an extratropical cyclone.

The North Atlantic Oscillation (NAO) is a weather phenomenon in the North Atlantic Ocean of fluctuations in the difference of atmospheric pressure at sea level (SLP) between the Icelandic Low and the Azores High. Through fluctuations in the strength of the Icelandic low and the Azores high, it controls the strength and direction of westerly winds and location of storm tracks across the North Atlantic. It is part of the Arctic oscillation, and varies over time with no particular periodicity.

Atlantic hurricane tropical cyclone that forms in the North Atlantic Ocean

An Atlantic hurricane or tropical storm is a tropical cyclone that forms in the Atlantic Ocean, usually between the months of June and November. A hurricane differs from a cyclone or typhoon only on the basis of location. A hurricane is a storm that occurs in the Atlantic Ocean and northeastern Pacific Ocean, a typhoon occurs in the northwestern Pacific Ocean, and a cyclone occurs in the south Pacific or Indian Ocean.

Eye (cyclone) region of mostly calm weather at the center of strong tropical cyclones

The eye is a region of mostly calm weather at the center of strong tropical cyclones. The eye of a storm is a roughly circular area, typically 30–65 kilometers in diameter. It is surrounded by the eyewall, a ring of towering thunderstorms where the most severe weather and highest winds occur. The cyclone's lowest barometric pressure occurs in the eye and can be as much as 15 percent lower than the pressure outside the storm.

Atlantic hurricane reanalysis project

The Atlantic hurricane reanalysis project of the National Oceanic and Atmospheric Administration seeks to correct and add new information about past North Atlantic hurricanes. It was started around 2000 to update HURDAT, the official hurricane database for the Atlantic Basin, which has become outdated since its creation due to various systematic errors introduced into the database over time. This effort has involved reanalyses of ship observations from the International Comprehensive Ocean-Atmosphere Data Set (ICOADS) as well as reanalyses done by other researchers over the years. It has been ongoing as of 2016, and should last another four years.

Tropical cyclogenesis

Tropical cyclogenesis is the development and strengthening of a tropical cyclone in the atmosphere. The mechanisms through which tropical cyclogenesis occurs are distinctly different from those through which temperate cyclogenesis occurs. Tropical cyclogenesis involves the development of a warm-core cyclone, due to significant convection in a favorable atmospheric environment.

Tropical cyclone rotating storm system with a closed, low-level circulation

A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain or squalls. Depending on its location and strength, a tropical cyclone is referred to by different names, including hurricane, typhoon, tropical storm, cyclonic storm, tropical depression, and simply cyclone. A hurricane is a tropical cyclone that occurs in the Atlantic Ocean and northeastern Pacific Ocean, and a typhoon occurs in the northwestern Pacific Ocean; in the south Pacific or Indian Ocean, comparable storms are referred to simply as "tropical cyclones" or "severe cyclonic storms".

Tropical cyclone observation

Tropical cyclone observation has been carried out over the past couple of centuries in various ways. The passage of typhoons, hurricanes, as well as other tropical cyclones have been detected by word of mouth from sailors recently coming to port or by radio transmissions from ships at sea, from sediment deposits in near shore estuaries, to the wiping out of cities near the coastline. Since World War II, advances in technology have included using planes to survey the ocean basins, satellites to monitor the world's oceans from outer space using a variety of methods, radars to monitor their progress near the coastline, and recently the introduction of unmanned aerial vehicles to penetrate storms. Recent studies have concentrated on studying hurricane impacts lying within rocks or near shore lake sediments, which are branches of a new field known as paleotempestology. This article details the various methods employed in the creation of the hurricane database, as well as reconstructions necessary for reanalysis of past storms used in projects such as the Atlantic hurricane reanalysis.

Effects of tropical cyclones effect of cyclone

The main effects of tropical cyclones include heavy rain, strong wind, large storm surges near landfall, and tornadoes. The destruction from a tropical cyclone, such as a hurricane or tropical storm, depends mainly on its intensity, its size, and its location. Tropical cyclones act to remove forest canopy as well as change the landscape near coastal areas, by moving and reshaping sand dunes and causing extensive erosion along the coast. Even well inland, heavy rainfall can lead to mudslides and landslides in mountainous areas. Their effects can be sensed over time by studying the concentration of the Oxygen-18 isotope within caves.

Hurricane Alley

Hurricane Alley is an area of warm water in the Atlantic Ocean stretching from the west coast of northern Africa to the east coast of Central America and Gulf Coast of the Southern United States. Many hurricanes form within this area. The sea surface temperature of the Atlantic in Hurricane Alley has grown slightly warmer over the past decades. A particularly warm summer in 2005 led climate scientists to begin studying whether this trend would lead to an increase in hurricane activity.

Mediterranean tropical-like cyclone Hurricane-like storms in the Mediterranean Sea

Mediterranean tropical-like cyclones, often referred to as medicanes but sometimes also as Mediterranean cyclones or as Mediterranean hurricanes, are meteorological phenomena observed over the Mediterranean Sea. On a few rare occasions, some storms have been observed reaching the strength of a Category 1 hurricane. The main societal hazard posed by Medicanes is not usually from destructive winds, but through life-threatening torrential rains and flash floods.

Tropical cyclones and climate change confluent article on tropical cyclones and climate change

Tropical cyclones and climate change concerns how tropical cyclones have changed, and are expected to further change due to climate change. The topic receives considerable attention from climate scientists who study the connections between storms and climate, and notably since 2005 makes news during active storm seasons. The 2018 U.S. National Climate Change Assessment reported that "increases in greenhouse gases and decreases in air pollution have contributed to increases in Atlantic hurricane activity since 1970."

African humid period Holocene climate period during which northern Africa was wetter than today

The African humid period (AHP) is a climate period in Africa during the late Pleistocene and Holocene geologic epochs, when northern Africa was wetter than today. The covering of much of the Sahara desert by grasses, trees and lakes was caused by changes in Earth's orbit around the Sun; changes in vegetation and dust in the Sahara which strengthened the African monsoon; and increased greenhouse gases, which may imply that anthropogenic global warming will also result in a shrinkage of the Sahara desert.

Quelccaya Ice Cap Glacier in Peru

The QuelccayaIce Cap is the second largest glaciated area in the tropics, after Coropuna. Located in the Cordillera Oriental section of the Andes mountains of Peru, the ice cap covers an area of 42.8 square kilometres (16.5 sq mi) with ice up to 200 metres (660 ft) thick. It is surrounded by tall ice cliffs and a number of outlet glaciers, the largest of which is known as Qori Kalis Glacier; the terrain surrounding the ice cap features lakes, moraines, peat bogs and wetlands and features a rich flora and fauna, including birds which have been observed to nest on the ice cap. Water from Quelccaya eventually nourishes the Inambari River and the Vilcanota River and is an important source of water.
