补充资料：天气
| 天气 weather 某一地区瞬时或短时段内的大气状态（如干湿、晴阴、风雨、冷暖等）及其变化的总称。气温、气压、湿度、风向和风速等气象要素的记录是表述天气的基本依据。天气和气候是既有联系又有区别的两个概念，气候是某一地区长期天气状况的综合表现。天气和人类的生活、经济活动有极为密切的关系。 天气总是处于不断的变化之中，在几分钟之内，可以由阳光灿烂、风平浪静转变为风暴骤起、波涛汹涌。同一时刻，各地的天气及其变化差别也很大，“夏雨隔牛背”、“十里不同天”就是这种差别的生动写照。然而天气变化是有规律可循的，在现代科学基础上发展起来的天气学，就是研究天气变化规律，并用科学方法进行天气预报的一门学问。人们不仅可以通过遍布全球的气象站网来观察天气的变化，还可通过气象雷达、气象卫星等先进探测工具探测大范围的天气变化；并可运用高速电子计算机求解大气动力方程组，制作大范围以至全球的数值天气预报。20世纪40年代以来，逐步开展了人工影响天气的科学试验。天气变化还有许多未知的领域，需要人们去探索和认识。 |
