| 摘 要： | 利用四川135个站自动与人工第二年平行观测相对湿度(下文简称湿度)资料,就自动与人工观测相对湿度的差异及引起差异的原因进行了分析。结果表明:相对湿度自动与人工观测相比,日平均值平均偏低2.7270%、月平均值平均偏低2.7970%、年平均值平均偏低2.7472%。56.35%的时次自动观测湿度值与人工观测湿度值的差值在5%以内,86.66%的时次自动观测湿度值与人工观测湿度值的差值在10%以内,2.61%的时次自动观测湿度值与人工观测湿度值的差值在20%以上。自动与人工观测湿度的差值无明显地域性差异。湿球纱布包扎不规范、纱布不清洁,干湿球温度表人工读数误差,干湿球温度表的通风状态,观测时间的不一致,自动观测在高湿状况下的非线性以及其他原因均会导致自动与人工观测湿度产生差异,甚至是显著差异。

| Abstract: | The data in the second year of relative humidity from Sichuan 135 stations observed by automatic and manual in parallel,are used to analyze the difference between the relative humidity information by automatic and manual observations,and the reasons for the differences.The parallel comparison observations indicated that the average daily relative humidity observed by automatic way was 2.727%less than that by manual way,the average monthly relative humidity observed by automatic way was 2.797%less than that ... |
