Abstract:In this paper ,the OLR field characteristics of the serious cold summer in theNortheast China have been found.According to the anomaly values of OLR field characteristics in the key region, the serious cold summer could be predicated half a year in advance.

Abstract:According to the observed data of two hailfall processes occured in the Mancheng county of Hebei Province during June 29, 1987, kinetic energy of hail-fall to the ground is preliminarily analysed in this paper.It is found that the, kinetic energy density (ET), the flux of kinetic energy (E), the mass .of hail (Mr) and the flux of mass (M) observed in the damaged areas are explicitly much higher than those of non-damaged areas.

Abstract:The indices of Walker Circulation and Hadley Circulation are defined on the basis of surface wind data set. The variation of the indices and the relationship between them as well as the El Nino.events are discussed.
