英语翻译
Daily changes in the weather affect all of us,no matter what our job or profession.However,while there`s very little we can do to modify the weather,we can at least know what kind of weather to expect.For this we are indebted to our efficient weather-watchers.
Although it may sound funny to call scientists weather-watchers,there`s nothing funny about what they do.Specifically,weather-watchers are meteorologists who work for the United States Weather Bureau.They study the ocean of air that surrounds the earth and,with the information they get,predict our weather.
The atmosphere ranges in height from 300to 700miles above the earth and is divided into a series of layers or shell.The layer that is most interesting to the meteorolgist is the troposphere or the layer closest to the earth.It is in the troposphere that all our weather is formed.
What causes our weather is really a very simple process,Endless streams of hot air push up from the earth.As they rise,they are c

答案

无论每个人的工作或职业,每日的气象变化影响着我们所有人.然而,尽管我们对于改变天气束手无策,不过我们至少可以有所准备.对于这一点,我们应该感谢我们高效的天气观察实.
虽然管那些科学家们叫天气观察师听起来有点逗趣,但他们的工作很严肃.具体而言,天气观察师是为美国气象局工作的气象学家们.他们观察研究围绕地球的空气,并从收集到的资料来预测天气.
在距离地面【海面】高300到700英里处有被划分成一系列的层或壳的大气层.气象学家最感兴趣的是最接近地球的那层,对流层.我们所有的天气的都在这对流层中形成.
导致天气【变化】的过程实际上非常简单.无尽的热空气流从地面升上,并在上升的过程中因遇到上层对流层的低温而冷却.冷却后,气体变沉后逐渐再沉落回地面,但因为遇到上升的热气流不能再沉落.与此同时,【行星】风在地球上环绕,或者说流动的空气使得冷气流团还有热气流团保持流动.
