山东省不同降水强度条件下的空中水汽资源量分析

Analysis on Water Vapour Resources Transportation at Different Precipitation Intensities in Shandong Province

利用 1 997-1 999年逐日探空资料和地面雨量资料 ,计算了山东省全年和不同降水强度等级下山东省域总水汽输入、输出和净水汽输入量 ,分析了不同降水等级的降水分布、各边界的水汽收支强弱、月际变化 ,以及相应的全省水汽净输入率的垂直分布和时间变化等特点。从水汽资源的角度分析了山东省“十年九旱”

Usng daily sounding and rainfall data from 1997 to 1999,the total water vapor input ,output and net water vapour input amount in whole year and different precipitation intensities were calculated.The characteristics of water vapour import and export ability,monthly variety along each boundaries as well as the plumb distribution and time change of net water input rate were analyzed too.Form the point of view of water vapour resources,the objective causes of drought climate characterisitics in Shandong were analysed.
