世界上一些地方天气非常多变,这对人们的生活有着很重要的影响.农民、渔民和水手必须提前知道这些变化.天文学家和航天飞行员尤其需要天气信息.
很久以前,人们就开始观察天空、风向和大气层以及其它一些天气信号来做天气预报.但所作出的预报基本都是错误的.现在很多地方都有自己的政府气象台来实时观测天气情况.他们使用一系列科学方法 来实现预测.如他们可以测出风向和风速.还能预测出风暴的前进方向.他们有特殊的气球、轮船和飞机来帮助他们提高预测的准确性.t他们还利用雷达、卫星和电脑来收集天气信息.
现在,当一架飞机从一个机场起飞时,飞行员就可以大体知道到达终点时当地的天气状况 ..如果山区有大雨或大雪,我们就能知道河流上涨的具体时间甚至是小时.当某一方向有风暴袭来的时候,当地的人就可以提前获悉并做好预防准备.
