补充资料：面雨量
面雨量
areal rainfal
m ianyuliang面雨量(ar己al rainfall)一定面积上的某时段内的平均雨量。计算面雨量的方法很多，最通用的是算术平均法或加权算术平均法，还有网格法和等雨量线图法等。算术平均法最简便，但精度不高。网格法和等雨量线图法精度较高。面雨量在水文气象学中的实用价值很大，在水文分析预报工作中，诸如分析降水天气区划，研究某一地区降水气候规律，旱涝变化特征以及暴雨洪水预报等都需要使用面雨量资料。精确的面雨量，必须有分布合理的点雨量或先进的探测技术。例如建立雨量自动化观测网，数字化天气雷达网，雷达计算机联网，自动化气象通讯网等，这些先进设备和技术的采用对面雨量精度的提高，将起到重要作用。(陈海龙)
