You see that white, fluffy cloud in the sky? How much do you think it weighs? I mean, its floating right? It can’t possibly weigh much, right?
你看到天上白色松软的云了吗?你觉得它有多重?我的意思是它在飘着吧?不可能太重,对吧?
Well, the average white cloud actually weighs around a 100 metric tons!
嗯,其实白云平均重量约100吨!
So how do they stay afloat? They stay afloat due to the rising warm currents of air which don’t let the water from the clouds fall!
那它们怎么能一直飘着呢?它们能一直飘着要归功于上升的暖气流不让云中的水掉下来!
Okay, so, If a white cloud weighs this much, how much would a black cloud weigh(The average storm cloud)?
好了,那么如果白云这么重,那乌云(普通的风暴云)会有多重?
A whopping 50,000 metric tons!! To get a perspective how heavy that is, it weighs the same as 280 blue whales!
重量惊人达50,000吨!!形象一点描述的话,这个重量相当于280头蓝鲸。
