超级单体雷暴(supercell thunderstorm)是一种破坏力最强的雷暴现象,其中心是一个中气旋,该气旋能够旋转上升几公里,并带来闪电、暴雨和大风(包括龙卷风),有时也会带来巨大的冰雹。
超级单体(Supercell)是雷暴的一种,拥有深厚、持续旋转上升气流的中气旋。由于这个原因,这些雷暴有时被称为旋转雷暴(rotating thunderstorms)。在雷暴的四种类型中(超级单体,飑线,多单体,和单体),超级单体是比较常见的,同时也是破坏力最大的一种。超级单体常常孤立于其他雷暴而存在,可以影响32千米(20英里)范围内的气候。
超级单体通常被分为三种类型:经典,低降水(LP)和高降水(HP)。低降水超级单体通常发生在干旱缺水地区,而高降水超级单体常发生在湿润地区,如美国的高原地区。虽然在符合发生条件的天气下,超级单体可能会出现在世界任何地方,但它们多数出现在北美大平原,一个以龙卷风走廊而闻名于世的地区。 http://www.dailymail.co.uk/sciencetech/article-1334672/Jaw-dropping-image-enormous-supercell-cloud-Glasgow-Montana.html
It looks like something from the film Independence Day.
But although it may seem like an alien mothership, this incredible picture is actually an impressive thunderstorm cloud known as a supercell.
Windswept dust and rain dominate the storm's centre while rings of jagged clouds surround the edge.
A flimsy tree in the foreground looks like a toy next to the magnificent natural phenomenon.
