摘　　要：After first reviewing historical and current difficulties in solving streamfunction and velocity potential in a limited domain,and describing recent developments in obtaining accurate solutions in a limited domain with arbitrary shape,a newly proposed approach is introduced and its application to a torrential rain event is reported.The results show that the newly developed method has advantages in capturing mesoscale information,compared with horizontal winds.After first reviewing historical and current difficulties in solving streamfunction and velocity potential in a limited domain,and describing recent developments in obtaining accurate solutions in a limited domain with arbitrary shape,a newly proposed approach is introduced and its application to a torrential rain event is reported.The results show that the newly developed method has advantages in capturing mesoscale information,compared with horizontal winds.
