| 摘 要： | 针对不同的防风标准在翻斗雨量计观测时对风场变形误差的防护作用,从降水总量随风速波动的变化、设备间的均方差及其相关系数和观测时间灵敏度等几个方面对观测数据进行分析。数据分析表明不同的防风标准翻斗式雨量计对风场变形误差的防护作用存在一定的差异,其中SMALLDIFR具有更高的时间灵敏性,在雨量比较大时,偏斜式雨量计更优。

| Abstract: | The protective effect of different windproof standard skip rain gauge is used to prevent the error of wind field deformation in observing.The author analyzes data from the amount changes of precipitation varying with wind speed fluctuations,standard deviation between devices,correlation coefficients and the sensitivity of the observing time.Data analysis result shows that there are some differences in protective effects which are used to prevent the error of wind field deformation in observation of the different windproof criteria of skip rain gauge.The SMALLDIFR shows higher time sensitivity.However,when the rainfall is relatively large,the deflection of rainfall observer is more fit. |
