Certain species of birds, as well as seismologists could predict tornadoes and other natural disasters, Current Biology reports with reference to the study by researchers at the University of California at Berkeley. Ornithologists have studied the birds that live in Central and North America.
The tornado (or tornadoes from the Spanish. Tornado «tornado») – atmospheric vortex arising cumulonimbus (thunderstorm) cloud and spreads down, often to the surface of the earth, in the form of a sleeve or cloud trunk diameter of tens to hundreds of meters. The development of a tornado cloud distinguishes it from some seemingly similar and also different in the nature of phenomena, such as Whirlwind and dust (sand) vortices. Usually transverse diameter of the funnel of a tornado in the lower-section of 300-400 m, though, if a tornado touches the surface of the water, this value may be as low as 20-30 m, and the passage of the funnel over land can reach 1.5-3 km
It turned out that zolotokrylye Vermivora able to predict the approach of hurricanes and tornadoes per day. Researchers were able to attach a special GPS-sensors to the birds and see the amazing phenomenon: birds displaced from their nesting, flying at 700 kilometers south of the Mexican Gulf happy wheels. On the day after their departure to the central part of the United States struck a wave of deadly tornadoes.
They made a flight of 5,000 miles after hibernation. However, suddenly flew to a distance of 700 to 1500 km. Just 24 hours later on the central part of the United States have fallen 84 tornadoes that have taken with them the life of 35 people and caused huge damage. According to the calculations of the authorities – a billion dollars. The weight of such birds only 9 grams, the experts tell of Kalifoniyskogo Berkeley.
According to Strabo Henry, one of the study’s authors, these tiny birds to approach can predict big storm. Vermivora (lat. Vermivora) – genus of birds of New World warbler family. Birds spread from North to Central America. Nesting places in North America.
The University of California at Berkeley (Eng. The University of California, Berkeley) – US public research university located in Berkeley, California. The oldest of the ten campuses of the University of California. In 2013, in the ranking of “National Universities” by the publication US News & amp; World Report ranked 20 th position, while at the same time, many educational programs are among the best in the country.
