中文摘要:本文提出一种相邻测站月(年)降水量Γ分布的间接估计模式。根据该模式,借助长序列(大样本)测站资料可间接估计短序列(小样本)测站的理论分布。推证表明,间接模式比直接由本站短序列记录估计理论分布提高了有效率并简化了拟合分布模式的计算。
 
AN INDIRECT MODEL FOR PROBABILITY DISTRIBUTION OF STATION PRECIPITATION
Abstract:An indirect estimation model for Gamma distribution of monthly (or yearly) Precipitation of a station with a short series of historical observations by means of the longer record of an adjacent station is presented. It is demonstrated that the indirect estimation is more realistic than the directly estimated theoretic distribution of station precipitation based on the small sample of record of its own. Moreover, the indirect method has simplified the calculation for fitting the distribution.
