Abstract:Flood season precipitation forecasts of 1993 were made with two new research results in the last two years except the routine methods many years ago. (1)The relation between earthquake field and precipitation field:there are weak earthquakes in the Pacific Ocean and Taiwan,this will benefit east China with much rainfall,from July 1992 to March 1993 six earthquakes of magnitude 2-3 occurred in the Changjiang river valley and the earthquakes in North China are very weak. This forebodes the high temperature area of the middle and lower reaches of Changjiang rivier,so we forecast in the northern part of the Changjiang river basin there will be much rain this year. (2) Developing rule of 3. 2 meter earth temperature anomaly field. There are 14 high temperature centers at the figure of 3. 2 meter earth temperature anomaly from Dec. 1992 to Feb. 1993. The historical development,suggest,that if high ternperature centers still exist or become strong,much rainfall could be received,otherwise,thexe will be less rainfall.
