【雕爷学编程】MicroPython动手做（33）——物联网之天气预报3

天气（自然现象）
是指某一个地区距离地表较近的大气层在短时间内的具体状态。而天气现象则是指发生在大气中的各种自然现象，即某瞬时内大气中各种气象要素（如气温、气压、湿度、风、云、雾、雨、闪、雪、霜、雷、雹、霾等）空间分布的综合表现。

天气过程就是一定地区的天气现象随时间的变化过程。各种天气系统都具有一定的空间尺度和时间尺度，而且各种尺度系统间相互交织、相互作用。许多天气系统的组合，构成大范围的天气形势，构成半球甚至全球的大气环流。天气系统总是处在不断新生、发展和消亡过程中，在不同发展阶段有着其相对应的天气现象分布。

天气预报
是应用大气变化的规律，根据当前及近期的天气形势，对某一地未来一定时期内的天气状况进行预测。它是根据对卫星云图和天气图的分析，结合有关气象资料、地形和季节特点、群众经验等综合研究后作出的。如我国中央气象台的卫星云图，就是我国制造的“风云一号”气象卫星摄取的。利用卫星云图照片进行分析，能提高天气预报的准确率。天气预报就时效的长短通常分为三种：短期天气预报（2～3天）、中期天气预报（4～9天），长期天气预报（10～15天以上），中央电视台每天播放的主要是短期天气预报。

天气预报的主要内容是一个地区或城市未来一段时期内的阴晴雨雪、最高最低气温、风向和风力及特殊的灾害性天气。就中国而言，气象台准确预报寒潮、台风、暴雨等自然灾害出现的位置和强度，就可以直接为工农业生产和群众生活服务。天气预报是根据气象观测资料，应用天气学、动力气象学、统计学的原理和方法，对某区域或某地点未来一定时段的天气状况作出定性或定量的预测。它是大气科学研究的一个重要目标。对人们生活有重要意义。
