Asian–Pacific Summer Monsoon Variability and Atmospheric Teleconnection Patterns: Review and Outlook

Circulation anomalies in one region sometimes cause circulation anomalies in other regions, and the correlation between such regional circulation anomalies is referred to as the atmospheric teleconnection. Chinese scientists have conducted extensive research on the atmospheric teleconnection patterns, particularly those related to the Asian–Pacific monsoon. This review first introduces the basic concepts and historical development of atmospheric teleconnections, and then presents an overview of the studies related to the Asian–Pacific monsoon in recent years, especially those on the subseasonal timescale. The paper systematically summarizes 26 teleconnection patterns, including their main features and associated pioneering works. Particular emphasis is placed on the East Asian–Pacific teleconnection pattern that propagates poleward along the low-level southwesterly monsoonal winds. The wave train-type teleconnection patterns propagating along the upper-level westerly jets are also briefly reviewed.
