　　主  题：Amplification of the subtropical stationary waves and their implications on regional water extremes

　　讲座内容介绍：

　　We investigate such a dynamical linkage by focusing on an amplification trend of the northern subtropical stationary waves found in recent decades and the response of such waves to increasing climate forcing using CMIP5 models. Pronounced changes in the subtropical atmospheric circulation accompany this wave amplification. Through modifying the characteristics of large-scale moisture transport, these circulation changes are coupled to changes in the regional precipitation amount and the occurrence of water extremes including both droughts and heavy rainfall events. We found that amplified stationary waves have likely contributed to the elevated occurrence probabilities of droughts in the central United States, Mexico, Japan, and northern China, as well as those of heavy rainfall events in South Asia, southeastern China, and the eastern United States.
