See and explore the power and the beauty of our planet's natural phenomenon. Tornadoes are formed when a special type of thunderstorm, called a supercell, pulls in warm humid air and pushes it through a powerful updraft. In the United States, this happens when warm moist air flowing up from the Gulf of Mexico meets the cool, dry air from Canada. The moisture in the updraft condenses into rain,causing a cool downdraft. In ordinary storms, the updraft turns into a downdraft, and the storm collapses. But in a supercell, the updraft and downdraft are separated so that one complements the other. See how these violent forces of Nature have shaped the earth through the ages and how they are still to be reckoned with even today. 看过电影《龙卷风》的观众,一定对电影中凌空飞舞的汽车动物,宛如雨下的断木残瓦,还余季犹在!在本篇中你不但会再次的感受到人类与自然灾害对抗的坚强意志力,更吸引人的是,这次面对的不再是神乎其技的电影特效,而是正真会夺走人命的龙卷风。在美国,每年有上百人因龙卷风之灾而丧命。Discovery Channel带您前往美国中西部、以夺命龙卷风闻名的“龙卷风带”实地考察,本片还收入了曾遭受龙卷风强烈袭击、并造成德州等地多人死亡的灾难实录。本片以美国的龙卷风为实l列,带你一览龙卷风的形成过程。看看分别来自墨西哥海湾和加拿大的两股温湿、‘干冷的气流,如何巧妙的扭成一股上升于下降同时并存的气流,形成横扫千军、夺命无数的龙卷风!
