摘要: 根据2006—2015 年逐年6—8 月吉林省52 个气象台站逐时降水资料,运用常规气象统计方法,采用逐时降水量、逐时降水频次、逐时降水强度和不同持续时间降水4 个指标对吉林省降水日变化特征进行研究。结果表明:吉林省夏季降水总量及日数的空间分布与纬度和海拔有关,表现为自南向北递减趋势,降水强度空间分布随海拔升高降水强度减小。吉林省小时降水量、降水频次及降水强度呈双峰型分布,峰值区分别为17:00—19:00、4:00—6:00、17:00—19:00;吉林省夏季持续1~3 h 降水量较大,其次是长持续性降水,持续时间为4~6 h 降水量最小。持续时间为1~3 h 降水量峰值出现在17:00,长持续性降水峰值出现在20:00,持续时间为4~6 h降水量峰值在1:00。

Abstract: Based on the hourly precipitation data of 52 meteorological stations in summer(from June to August) over Jilin province form 2006 to 2015, the commonly used meteorological statistical methods are applied. we analyze the diurnal variation characteristics of precipitation in summer over Jilin province by using four precipitation indices(hourly precipitation, hourly precipitation frequency, hourly precipitation intensity and precipitation duration).The results showed that the spatial distribution of total precipitation and number of days in summer over Jilin province was related to latitude and altitude, showing a decreasing trend from south to North. The spatial distribution of precipitation intensity decreases with increasing altitude. The distribution of hourly precipitation, precipitation frequency and precipitation intensity in Jilin province showed a bimodal distribution, with the peak areas being 17:00-19:00, 4:00-6:00 and 17:00-19:00 respectively. In summer, the first total precipitation was 1-3h short-time rainfall, the second was long continuous precipitation, the least was 4-6h continuous precipitation. The peak of precipitation occurred in 17:00 of 1-3h short-time rainfall, the long continuous precipitation peak appeared at 20:00 and 4-6h continuous precipitation peak occurred in 1:00.
