风,是一种很常见的自然现象,我们都习以为常。但是,大自然也经常会造出一些怪风。你知道吗?有一句俗语“:清明前后刮鬼风。”这种所谓的“鬼风”能转着圈跟着人走。世上当然是没有鬼的,这种风其实是一种尘卷风,一旦遇到障碍物,它便会改变前进的方向,在一个地方打转,有时它还挟带着泥沙、纸屑旋转上升。有一种叫“焚风”的风,最早是指气流越过阿尔卑斯山后,在德国、奥地利和瑞士山谷出现的一种风。 Wind, is a very common natural phenomenon, we are accustomed to. However, nature often produces some weird winds. Do you know? There is a common saying “: Ghostly wind before and after the Qingming. ” This so-called “Ghost Wind ” can be followed by people in circles. Of course, there is no ghost in the world. This wind is actually a kind of dust-laden wind. Once an obstacle is encountered, it will change the direction of its forward movement and turn around in one place. Sometimes it carries sediment and the paper dust rotates upwards . There is a kind of wind called “burning the wind ”, the first refers to the air flow across the Alps, in Germany, Austria and Switzerland, a wind that appears in the valley.
