Overview The upper troposphere-lower stratosphere （UTLS） of the Asian summer monsoon （ASM） region is characterized by a continental-scale anticyclonic circulation, which is dynami- cally active and coupled to monsoonal convection. The monsoon anticyclone exhibits anomalous chemical and aerosol characteristics, linked to the outflow of deep convection and the large-scale circulation, and strongly influences the global UTLS composition during boreal summer.展开更多
文摘1. Overview The upper troposphere-lower stratosphere （UTLS） of the Asian summer monsoon （ASM） region is characterized by a continental-scale anticyclonic circulation, which is dynami- cally active and coupled to monsoonal convection. The monsoon anticyclone exhibits anomalous chemical and aerosol characteristics, linked to the outflow of deep convection and the large-scale circulation, and strongly influences the global UTLS composition during boreal summer.
