摘　　要：利用武汉、黄陂、黄石三气象站合计9 a的自动、人工观测(雨量自记纸)同期分钟雨量数据及雨量筒资料,对两种观测方式下的年雨量、月雨量、日雨量偏差程度、暴雨日短历时降水、不同时段的短历时雨量进行了比较。结果发现:自动观测比人工观测(雨量自记纸)雨量偏大,两者的偏差程度主要在±10%之间。自动观测雨量结果与雨量筒更为吻合。3站多年自动、人工观测(雨量自记纸)两套暴雨日短历时(历时5 min)雨量序列高度相关。Using the minute rainfall data by Automatic Recording and Manual Observation and the raingauge data at the same period for nine years from Wuhan, Huangpi and Huangshi weather stations, the annual rainfall, monthly rainfall, the variation degree of daily rainfall, the process of short-duration rainfall(storm),and the amount of short-duration rainfall are compared between the two observation mode. The result shows that the rainfall amount by automatic recording is much larger than that by manual observation, The degree of deviation between the two methods is mainly within±10%. The rainfall observed by automatic method is much more consistent to the result of raingauge than that by annual observation. The daily short duration(for 5 minutes) rainfall series between automatic and annual observations are highly correlated.
