Many results of the process on abstract spaces and Euclidean spaces are obtained in the literature. In this paper, we discuss super-Brownian motions on two space forms and reveal partially the relationship between the properties of superprocesses and the geometric structure of the underlying state spaces. Finally, we also presents some open problems.展开更多

Based on the simulations,the authors investigate the effects of Qinghai-Xizang Plateau snow cover on the formation of South Asian monsoon by thickcning the snow depth and by increasing the snow albedo.The main results arc as follows:The summer meridional circulation over the south of the Plateau and its vicinity is weakeued,and the precipitation reduced.However,over the northern tropics,the circulation is enhanced, and the ecipitation is increased,and the land and the air above it become warmer,the tropical easterly jet is weakened.展开更多
