| 摘 要： | 在春夏连续少水年的降水时空分布特征分析的同时,又对少水时逐旬环流配置进行归类分型,并利用500hPa数值预报产品作实时降水过程预报。通过分析,少水年主要天气现象特征是较大降水发生频次少,少水旬约占67%,与其相对应的高空环流特征有77.8%旬环流配置属于不利于降水天气形势。

| Abstract: | The real time precipitation forecast was done by applying the characteristic analysis of the time -space distribution of precipitation and classifying of ev ery five days circulation correspon ding with the water shortage and appl ying numerical forecast data of 500mb.We have got the conclusion that the main characteristic of t he water shortage year belonged to le ss frequency of more precipitation,every five days water shortage was about 67%,and 77.8%corresponding high level circula tion was not suitable for raining. |
