Role of the monsoon trough and tropical cyclone activity on the interannual and long-term variations of the Asian monsoon precipitation
Abstract
The interannual variations of the Asian monsoon precipitation are associated with the tropical cyclone activity over the western North Pacific. To understand the tropical cyclone activity over the western North Pacific, the monsoon trough of the Asian monsoon can be a key factor. For the tropical cyclone activity, the condition of the monsoon trough can be understood as the external factor. However, the monsoon trough can be also understandable as the result of the tropical cyclone activity over the western North Pacific, which was explained by some previous studies. The monsoon trough can be associated with the tropical Asian monsoon circulations. Also, the precipitation from the tropical cyclone activity can control the precipitation over the Asian monsoon regions. Thus, there is an interaction among the Asian monsoon precipitation, the monsoon trough, and the tropical cyclone activity. This study discusses the interaction between them and their future changes under a warming climate.
