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]

History

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]

Explanations

French physicist André-Marie Ampère (1775–1836) was among the first scientists to take 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. On October 24, 1987(several occurrences within two weeks), three towns of Gloucestershire, England named, Stroud, Cirencester, and Cheltenham reported, by various people, about a heavy rain fall that also brought down dozens of tiny pink frogs. Some suggested strong winds, waterspouts, or tornados carried the frogs' eggs flying north across Africa, until falling on England. [9]

A current scientific hypothesis involves tornadic waterspouts: a tornado that forms over the water. [1] [10] [11] [12] 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, [13] 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. [14] 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. [15]

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. [16] 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. [17] 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. [18] 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, [19] though many scientists claim such mass deaths are common occurrences but usually go unnoticed. [20] 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. Several residents of a landlocked city, in east Texas have reported a rare sight seeing fish all over the ground after they apparently fell from the sky during a rainstorm. Independent researchers, Sharon A. Hill and Paul Cropper, proposed that the fish had been dropped or possibly regurgitated by passing birds. [21] 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. [22]

<span class="mw-page-title-main">Tornado</span> Rotating air column connecting the Earth’s surface and a cumulonimbus cloud

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), can be more than 3 kilometers (2 mi) in diameter, and can stay on the ground for more than 100 km (62 mi).

<span class="mw-page-title-main">Waterspout</span> Vortex or tornado occurring over a body of water

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.

<span class="mw-page-title-main">Star jelly</span> Gelatinous substance sometimes found on the ground

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 tropical semi arid 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, with annual rainfall projected to reach over 500 mm by 2100. For this reason, the city may be classed as almost semi-arid (BSh), since it has a mild climate with a short but defined wet season, along with a lengthy dry season.

<span class="mw-page-title-main">Western disturbance</span> Extratropical storm over north India

A western disturbance is an extratropical storm originating in the Mediterranean region that brings sudden winter rain to the northwestern parts of the Indian subcontinent, which extends as east as up to northern parts of Bangladesh and South eastern Nepal. It is a non-monsoonal precipitation pattern driven by the westerlies. The moisture in these storms usually originates over the Mediterranean Sea, the Caspian Sea and the Black Sea. Extratropical storms are a global phenomena with moisture usually carried in the upper atmosphere, unlike their tropical counterparts where the moisture is carried in the lower atmosphere. In the case of the Indian subcontinent, moisture is sometimes shed as rain when the storm system encounters the Himalayas. Western disturbances are more frequent and stronger in the winter season.

Blood rain or red rain is a phenomenon in which blood is perceived to fall from the sky in the form of rain. Cases have been recorded since Homer's Iliad, composed approximately 8th century BC, and are widespread. Before the 17th century it was generally believed that the rain was actually blood. Literature mirrors cult practice, in which the appearance of blood rain was considered a bad omen. It was used as a tool foreshadowing events, but while some of these may be literary devices, some occurrences are historic. There is now a scientific consensus that the blood rain phenomenon is caused by aerial spores of green microalgae Trentepohlia annulata.

The Melanau calendar is a calendar used by the Melanau people of Borneo. Its year consists of 12 months. The first month, Pengejin, signifies the celebration of the Kaul festival. Each month in the Melanau calendar consists of 30 days. It is guided by the constellations, natural phenomena and guardian spirits. Each month is named for occurrences during the month or events which are supposed to have occurred during that particular month, according to legend. The rise and fall of the Sun, the Moon and the stars determine the time for planting, harvesting, fishing, building, travel and marriage.

The climate of Uttar Pradesh is a tropical monsoon climate, consisting mainly of a humid subtropical climate with dry winter (Cwa). Parts of western Uttar Pradesh consist of a hot semi-arid climate (BSh). The uniformity of the vast Indo-Gangetic Plain covering most of the state causes it to have a predominantly single climate pattern with minor regional variations.

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.

<span class="mw-page-title-main">Tropical Storm Beryl (2012)</span> Atlantic tropical storm

Tropical Storm Beryl was the strongest off-season Atlantic tropical cyclone on record to make landfall in the United States. The second tropical cyclone of the 2012 Atlantic hurricane season, Beryl developed on May 26 from a low-pressure system offshore North Carolina. Initially subtropical, the storm slowly acquired tropical characteristics as it tracked across warmer sea surface temperatures and within an environment of decreasing vertical wind shear. Late on May 27, Beryl transitioned into a tropical cyclone less than 120 miles (190 km) from North Florida. Early the following day, the storm moved ashore near Jacksonville Beach, Florida, with peak winds of 65 mph (100 km/h). It quickly weakened to a tropical depression, dropping heavy rainfall while moving slowly across the southeastern United States. A cold front turned Beryl to the northeast, and the storm became extratropical on May 30.

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.
