| Abstract: | By analyzing the "98 6" succesive torrential rain processes in Guilin,this paper reveals the maintaining mechanism of the general circulation in the period,and the main cause for maintenance of torrential rain.In addition,the inherent relation of the succesive torrential rain with low level jets and their ageostrophic winds is also analyzed.It is pointed out that the rain peaks in the succesive torrential rain are directly related with the activity of warm low vortices in southwest China and low level jets. |
