A rain of animals is a rare meteorological phenomenon in which flightless animals fall from the sky. Such occurrences have been reported in many countries throughout history. [1] One hypothesis is that tornadic waterspouts sometimes pick up creatures such as fish or frogs, and carry them for up to several miles. [1] [2] However, this aspect of the phenomenon has never been witnessed by scientists. [3]
Rain of flightless animals and things has been reported throughout history. [1] In the first century AD, Roman naturalist Pliny the Elder documented storms of frogs and fish. [4] In 1794, French soldiers saw toads fall from the sky during heavy rain at Lalain, near the French city of Lille. [5] Rural inhabitants in Yoro, Honduras claim "fish rain" happens there every summer, a phenomenon they call Lluvia de Peces, although the name may be indoctrination from a Spanish missionary as the fish have only been found near tributaries after storms. [6]
French physicist André-Marie Ampère (1775–1836) was among the first scientists to take seriously accounts of raining animals. Addressing the Society of Natural Science, Ampère suggested that at times frogs and toads roam the countryside in large numbers, and that violent winds could pick them up and carry them great distances. [3]
After a reported rain of fish in Singapore in 1861, French naturalist Francis de Laporte de Castelnau speculated that a migration of walking catfish had taken place, dragging themselves over land from one puddle to another, following the rain. [7]
The likeliest explanation for many of the supposed cases is that there is no falling happening at all and the animals are driven along by winds or a deluge of some sort. [8] This explanation also accounts for the prevalence of reports that only a single species or type of animal is ever reported raining from the sky.
A current scientific hypothesis involves tornadic waterspouts: a tornado that forms over the water. [1] [9] [10] [11] Under this hypothesis, a tornadic waterspout transports animals to relatively high altitudes, carrying them over large distances. This hypothesis appears supported by the type of animals in these rains: small and light, usually aquatic, [12] and by the suggestion that the rain of animals is often preceded by a storm. However, the theory does not account for how all the animals involved in each individual incident would be from only one species, and not a group of similarly sized animals from a single area. [13] Further, the theory also does not account for a genuine tornadic waterspout not actually sucking objects up and carrying them rather than flinging objects out to the sides. [14]
In the case of birds, storms may overcome a flock in flight, especially in times of migration. The Doppler image to the right shows an example wherein a group of bats is overtaken by a thunderstorm. [15] In the image, the bats are in the red zone, which corresponds to winds moving away from the radar station, and enter into a mesocyclone associated with a tornado (in green). These events may occur easily with birds, which can get killed in flight, or stunned and then fall (unlike flightless creatures, which first have to be lifted into the air by an outside force). Sometimes this happens in large groups, for instance, the blackbirds falling from the sky in Beebe, Arkansas, United States on December 31, 2010. [16] It is common for birds to become disoriented (for example, because of bad weather or fireworks) and collide with objects such as trees or buildings, killing them or stunning them into falling to their death. The number of blackbirds killed in Beebe is not spectacular considering the size of their congregations, which can be in the millions. [17] The event in Beebe, however, captured the imagination and led to more reports in the media of birds falling from the sky across the globe, such as in Sweden and Italy, [18] though many scientists claim such mass deaths are common occurrences but usually go unnoticed. [19] In contrast, it is harder to find a plausible explanation for rains of terrestrial animals.
Some cases are thought to be caused by birds dropping fish. With regard to a documented rain of fish that occurred on December 29, 2021 in Texarkana, Texas, independent researchers Sharon A. Hill and Paul Cropper proposed that the fish had been dropped or possibly regurgitated by passing birds. [20] The theory found some favor with airport workers who had cleaned up the fish; they noted that there were birds in the area around the same time, and the fish "were kind of chewed up". In June 2022 around the San Francisco coast, a boom of anchovies is likely to be the cause of fair weather falling of fish from birds' mouths, such as pelicans. [21]
The following list is a selection of examples.
A tornado is a violently rotating column of air that is in contact with both the surface of the Earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. It is often referred to as a twister, whirlwind or cyclone, although the word cyclone is used in meteorology to name a weather system with a low-pressure area in the center around which, from an observer looking down toward the surface of the Earth, winds blow counterclockwise in the Northern Hemisphere and clockwise in the Southern. Tornadoes come in many shapes and sizes, and they are often visible in the form of a condensation funnel originating from the base of a cumulonimbus cloud, with a cloud of rotating debris and dust beneath it. Most tornadoes have wind speeds less than 180 kilometers per hour, are about 80 meters across, and travel several kilometers before dissipating. The most extreme tornadoes can attain wind speeds of more than 480 kilometers per hour (300 mph), are more than 3 kilometers (2 mi) in diameter, and stay on the ground for more than 100 km (62 mi).
Texarkana is a city in Bowie County, Texas, United States, in the Ark-La-Tex region. Located approximately 180 miles (290 km) from Dallas, Texarkana is a twin city with neighboring Texarkana, Arkansas. The Texas city's population was 36,193 at the 2020 census.
The climate of Mumbai is tropical, with defined wet and dry seasons. The mean annual temperature is 27.7 °C or 81.9 °F. Average annual rainfall is 2,213.4 millimetres or 87 inches in Colaba, which represents South Mumbai and 2,502.3 millimetres or 99 inches in Santacruz, which represents central and suburban Mumbai. The mean maximum average temperatures is about 32 °C (90 °F) in summer and 30 °C (86 °F) in winter, while the average minimums are 26 °C (79 °F) in summer and 18 °C (64 °F) in winter. The city experiences a lengthy, practically rainless dry season, and a relatively short, but extremely rainy wet season; due to the Southwest Monsoon and orographic influences from the nearby Western Ghats.These conditions effectively place Mumbai between a Tropical monsoon climate (Am) and a Tropical savannah climate (Aw), with more tilt towards the former considering annual precipitation.
Yoro is one of the 18 departments into which Honduras is divided. The department contains rich agricultural lands, concentrated mainly on the valley of the Aguan River and the Sula Valley, on opposite ends. The departmental capital is Yoro. The department covers a total surface area of 7,939 km2 and, in 2005, had an estimated population of 503,886 people. It is famous for the Lluvia de Peces, a tradition by which fish fall from the sky during very heavy rains.
Weather lore is the body of informal folklore related to the prediction of the weather and its greater meaning.
A waterspout is a rotating column of air that occurs over a body of water, usually appearing as a funnel-shaped cloud in contact with the water and a cumuliform cloud. There are two types of waterspout, each formed by distinct mechanisms. The most common type is a weak vortex known as a "fair weather" or "non-tornadic" waterspout. The other less common type is simply a classic tornado occurring over water rather than land, known as a "tornadic", "supercellular", or "mesocyclonic" waterspout, and accurately a "tornado over water". A fair weather waterspout has a five-part life cycle: formation of a dark spot on the water surface; spiral pattern on the water surface; formation of a spray ring; development of a visible condensation funnel; and ultimately, decay. Most waterspouts do not suck up water.
Yoro, with a population of 27,460, is the capital city of the Yoro Department of Honduras and the municipal seat of Yoro Municipality. It is notable for a local event known as Lluvia de Peces, where it is claimed that strong storms make fish fall from the sky.
Star jelly is a gelatinous substance sometimes found on grass and less commonly on the branches of trees. According to folklore, it is deposited on the Earth during meteor showers. It is described as a translucent or grayish-white gelatin that tends to evaporate shortly after having "fallen". Explanations have ranged from it being the remains of frogs, toads, or worms, to the byproducts of cyanobacteria, to being the fruiting bodies of jelly fungi or masses of amoeba called slime molds. Nonbiological origins proposed for instances of "star jelly" have included byproducts from industrial production or waste management. Reports of the substance date back to the 14th century and have continued to the present.
Karachi has a semi-arid climate, formerly a hot desert climate, albeit a moderate version of this climate, influenced by monsoons. Karachi has a tropical climate, despite being located slightly above the Tropic of Cancer. It is situated in the monsoon region of Pakistan. It is located on the coast bordering the Arabian Sea, and as a result, has a relatively mild climate. However, in more recent years, rainfall has become more abundant. For this reason, the city may be classed as semi-arid (BSh), since it has a mild climate with a short but defined wet season, along with a lengthy dry season.
The Kerala red rain phenomenon was a blood rain event that occurred in Wayanad district of southern Indian state Kerala on Monday, 15 July 1957 and the colour subsequently turned yellow and also 25 July to 23 September 2001, when heavy downpours of red-coloured rain fell sporadically in Kerala, staining clothes pink. Yellow, green and black rain was also reported. Coloured rain was also reported in Kerala in 1896 and several times since, most recently in June 2012, and from 15 November 2012 to 27 December 2012 in eastern and north-central provinces of Sri Lanka.
Landfall is the event of a storm moving over land after being over water. More broadly, and in relation to human travel, it refers to 'the first land that is reached or seen at the end of a journey across the sea or through the air, or the fact of arriving there.
The lluvia de peces, also known as aguacero de pescado, is a phenomenon that has been occurring yearly for more than a century in Yoro, Honduras, in which fish are said to fall from the sky. It occurs up to four times in a year. It has attracted the attention of scientists, as well as documentary coverage by the History Channel in the United States.
Tornadogenesis is the process by which a tornado forms. There are many types of tornadoes and these vary in methods of formation. Despite ongoing scientific study and high-profile research projects such as VORTEX, tornadogenesis is a volatile process and the intricacies of many of the mechanisms of tornado formation are still poorly understood.
The British Overseas Territory of Bermuda has been affected by several tornadoes and waterspouts in its history.
Wild Africa is a British nature documentary series created and produced by the BBC. It explores the natural history of the African continent. It was first transmitted on 7 November 2001 on BBC Two in the United Kingdom and comprises six episodes. Each concentrates on a particular environment. The producers use aerial photography and wildlife footage to show how natural phenomena such as seasonal changes influence the patterns of life. Wild Africa was produced by the BBC Natural History Unit and narrated by Fergal Keane.
Bird kill is a localized event resulting in the death of large numbers of birds at the same time.
The Kentucky meat shower was an incident occurring for a period of several minutes between 11 a.m. and 12 p.m. on March 3, 1876, where what appeared to be chunks of red meat fell from the sky in a 100-by-50-yard (90-by-45-meter) area near Olympia Springs in Bath County, Kentucky. There exist several explanations as to how this occurred and what the "meat" was. Although the exact type of meat was never identified, various reports suggested it was beef, lamb, deer, bear, horse, or possibly human.
The 2013 Southeastern United States floods were ongoing flooding across the southeastern U.S. Flash floods began on the morning of July 2 and continued through Independence Day and into the next day. The hardest-hit areas as of Friday afternoon are the Florida Panhandle, northwest Alabama and the area around Columbus, Mississippi. A plume of tropical moisture caused heavy rain to train over the same areas, for more than 36 hours in some cases, leading to flash flooding.
A mass mortality event (MME) is an incident that kills a vast number of individuals of a single species in a short period of time. The event may put a species at risk of extinction or upset an ecosystem. This is distinct from the mass die-off associated with short lived and synchronous emergent insect taxa which is a regular and non-catastrophic occurrence.
The following is a list of weather events that occurred on Earth in the year 2022. The year began with a La Niña. There were several natural disasters around the world from various types of weather, including blizzards, cold waves, droughts, heat waves, wildfires, floods, tornadoes, and tropical cyclones. The deadliest weather event of the year were the European heat waves, which killed over 26,000 people, 11,000 of which were in France. The costliest weather event of the year was Hurricane Ian, which caused at least $112.9 billion in damages in Florida and Cuba. Another significant weather event was the Pakistan floods, which killed 1,739 people and a total of $14.9 billion in damages.
