摘要
本文在常规观测资料基础上用三次排空法较好地解决了单站暴雨的12—36小时预报问题.在1986—1988年6月份的暴雨预报试验中,长沙发生的三次达标暴雨(R日≥40mm/日)均报准.这可能意味着三次排空法基本上抓往了暴雨形成的主要机制。
In this paper, the three-time-exclusion method has been used on the base of the ordinary observation data and the problem of the forecast of single-station storm rainfall from 12 to 36 hours has been solved fairly well. In the test of the storm rainfall forecast in June of the three years (from 1986 to 1988), the three storm rainfalls reaching the standard (R>40mm perday) which occurred in Chang Sha were forecasted exactly. It means that the three-time-exclusion method has fundamentally caught the main mechanism of forming the storm rainfall.
