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 cooled by the freezing temperatures of the upper troposphere.Once it has become cold and heavy,the air sinks back toward the earth,but it can`t move down because of the rising hot air,In the meantime,planetary winds,which blow around the earth,or air currents keep both the cold air mass as well as the hot air mass in motion.

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.

每一天，天气的变化会影响每个人-无论你是贩夫走卒抑或是达官贵人，对天气是束手无策，我们该感激我们的天气预测师让我们对天气变化较有所准备。
对那些天气·预测科学家这样的称呼一点也不为过，因为，在美国气候局，气候的观察师是气象师。他们观察地球周围的海洋气候，把其信息的收集，预测等。
大气层的高度是介于海拔300到700里；它还可以分为一系列的层次/界面。气象师最关心的是那层最接近地面的...

每一天，天气的变化会影响每个人-无论你是贩夫走卒抑或是达官贵人，对天气是束手无策，我们该感激我们的天气预测师让我们对天气变化较有所准备。
对那些天气·预测科学家这样的称呼一点也不为过，因为，在美国气候局，气候的观察师是气象师。他们观察地球周围的海洋气候，把其信息的收集，预测等。
大气层的高度是介于海拔300到700里；它还可以分为一系列的层次/界面。气象师最关心的是那层最接近地面的对流层。对流层就是我们所谓的气候。
天气变化的过程其实是简明的：当无数的热空气上升时，遇到冷的上层对流层就会冷却。当这些被冷却气体变大时，就会下沉，但是还有上升的热气，它们不能再往下降，与此同时（行星）风会吹向地面，还有，空气的流动也会使冷和热的空气团的流动！
