沙塵暴(翻譯) 急需!!!!!

造成沙塵暴的原因既有自然的,也有人爲的。

1.造成沙塵暴的原因

砍伐森林會造成大片土地的沙漠化,而沙漠化顯然就會導致風暴帶有大量砂土。在近幾百年來,人類為了經濟生產而大量砍伐森林,挖掘其他自然資源,這些行為嚴重破壞了我們周圍的自然環境,沙塵暴現象在世界一些地區的頻繁化就是後果之一。

2.沙塵暴是什麼

「沙塵暴」是指強風將地面大量的沙和土粒捲揚起來,使空氣變得混濁、能見度大為減小的災害性天氣現象。在氣象測計中規定,凡水平方向能見度小於1000公尺的風沙現象,稱為「沙塵暴」;如果風力加到8-9級、被颳起的沙塵增多、天空變得越來越混濁、能見度小於200公尺,稱為「強沙塵暴」;如果風力再加大到超過10級、能見度小於50公尺,稱為「特強沙塵暴」。由於發生強和特強沙塵暴時天色昏暗,甚至黑得伸手不見五指,因此在中國西北地區,居民又將之稱為「黑風」或「黑風暴」。

3.沙塵暴的定義

沙塵暴是沙漠和塵暴兩者兼有的總稱,是大量沙塵物質被強風吹到空中,使空氣很混濁(水平能見度 < 1000米)的嚴重風沙天氣現象。形成沙塵暴的三個基本條件:首先風是沙塵暴的原始驅動力;其次是沙源;第三,地表受熱後產生一種不穩定的上升氣流,把地面的沙塵帶到高空,從而形成沙塵暴。

    Creates the sand storm the reason already to have naturally, also some people 爲.
