On that hot, muggy afternoon, a supercell thunderstorm formed over southeastern Kansas.

在那个炎热闷热的下午，一场超级单体雷暴形成了在堪萨斯州东南部。

In intense thunderstorms like supercell thunderstorms, warm, moist air shoots up into the atmosphere, cooling as it rises.

在像超级单体雷暴这样的强烈雷暴中，温暖潮湿的空气会喷射到大气中， 并在上升时冷却。

Some of the storms that developed were supercell thunderstorms — the really severe kind that can have super strong winds, cause flash flooding … and sometimes produce tornadoes.

形成的一些风暴是超级单体雷暴——真正严重的那种，可能会产生超强风，导致山洪暴发… … 有时还会产生龙卷风。

The winds inside a thunderstorm aren't simply up and down; horizontal winds exist from either a rotating updraft, like in supercell thunderstorms, or from the surrounding environment's horizontal winds.

雷暴中的风不只是上下起伏；水平风来自旋转的上升气流， 如超级单体雷暴， 或来自周围环境的水平风。
