Meteoreology: Thunderstorms and Tornadoes

Meteorology includes research on weather and climate. Meteorologists are particularly interested in studying the occurrence of thunderstorms and tornadoes. Arashi's research and observation began as a hobby of Howard B. Brewstein. Bustein 's interest in meteorology began with cloud pictures. After acquiring a degree in electrical engineering, he continued with the graduate school of meteorology. In his book "Storm of the Great Plain", Brustein talks about his experience of studying tornades following the storm.

The tornado is spinning rapidly, and the air generated from the thunderstorm is on the ground. The composition of the tornado is a thunderstorm, the speed is varied but rises sharply. When thunderstorms occur, you can see that the clouds are piled up. This rising air is the cause of all rain and hail formed from the water in the air. Increasing the wind speed and wind direction as the height increases will cause the rising air to rotate. Please consider turning on. Rotate your finger in the opposite direction and rotate the upper part. This is the same as the wind from different directions. Most thunderstorms do not produce tornadoes, as rotation is not balanced with rising air from the surface of the earth. When the balance between rising air current entering the thunderstorm and the wind changing depending on height happens, then a tornado can be formed. The tornado may be weak or strong, and lasts from a few seconds to several minutes.

Most tornadoes are formed by rising air currents that rotate strongly during a supercell thunderstorm. It is thought that the difference of vertical wind shear is the cause of tornado rotation. Large scale rotation in a strong thunderstorm is called medium and low pressure, and tornado is extension of medium and low pressure. Today, the United States can get excellent flash animation formed by a tornado

A tornado is a pillar of vigorously rotating air, extending from the bottom of a cumulonimbus cloud (thunderstorm etc) to the ground. Tornades are often (although not always) displayed as funnel clouds. Since tornadoes and hurricanes are very different phenomena, it is important not to confuse tornadoes with hurricanes and other tropical cyclones. Perhaps the only similarity between a tornado and a hurricane is that they all contain a strong rotating wind that can cause damage. There are many differences between tornadoes and hurricanes. The largest tornado observed every time is 4 km (2.5 miles) wide, and most tornadoes are less than 0.8 km (0.5 mile) wide. The father's storm cloud that generates a tornado is usually about 16 kilometers (10 miles) in width. However, hurricanes are usually much larger, and the width is about 160 km (100 miles) to 1600 km (1000 miles) (see Hurricane structure and main cycle). Tornado's life is very short, ranging from a few seconds to a few hours.
