摘要： 表示降水气候特征的指标,通常有数量(雨量)和持续时间两个方面(雨强即为单位时间内的雨量)。降水持续时间的指标各国目前只用雨日(降水日数),因而并不是实际降水持续时间(降水时数)。

Abstract: In China, in the definition of duration of precipitation, the number of precipitation day is used only. In general, the precipitation day is defined as the rainfall ≥0.1 mm within24 hours, but the duration of rain is not considered, which is not sufficient to describe the nature of precipitation.
