The weather in Florida
First, let us know what a tornado is. Tornado is a rare local, small-scale and sudden strong convective weather, and it is a strong and small-scale air vortex caused by air convection movement under strong unstable weather conditions.
Generally speaking, tornadoes are destructive. Tornadoes are not common in China, but they are extremely active and powerful in the United States. The reason is:
1.? The influence of special topographical features in the United States. The United States is bordered by the Atlantic Ocean in the east and the Pacific Ocean in the west. The Appalachian Mountains and Labrador Plateau are in the east of the North American continent. The terrain is relatively high, the Rocky Mountains in the west and the Great Plains in the middle are high from east to west, and there are no mountain obstacles in the north and south. Therefore, the Gulf Stream will transport a lot of water vapor from the south to the Central American continent. This convective system formed by a large amount of water vapor brings unstable energy in the atmosphere and leads to updraft. This has formed the primary condition of strong convective weather. 2. The second is the latitude position of the United States. The United States has a large land area, and most areas are in the mid-latitude position. In spring and summer, under the influence of strong subtropical high, the temperature difference between the upper and lower clouds is too large, and the condition of sufficient water vapor leads to the decline of cold air in the upper air and the rise of hot air on the ground, forming strong convective weather, thus forming convective vortex, that is, tornado. Generally speaking, the frequent occurrence of tornadoes in the United States is mainly due to the influence of topography and special latitude position. Because tornadoes are particularly powerful and have great destructive effects, buildings and other buildings in areas where tornadoes pass are often damaged to varying degrees or even collapsed. Therefore, people in areas affected by tornadoes, especially their families and neighbors, can help themselves and each other as soon as possible after the disaster, minimizing casualties.
