| Abstract: | Recent advances in the study of the characteristics, processes, and causes
of spatio-temporal variabilities of the East Asian monsoon (EAM) system are
reviewed in this paper. The understanding of the EAM system has improved in
many aspects: the basic characteristics of horizontal and vertical
structures, the annual cycle of the East Asian summer monsoon (EASM) system
and the East Asian winter monsoon (EAWM) system, the characteristics of the
spatio-temporal variabilities of the EASM system and the EAWM system, and
especially the multiple modes of the EAM system and their spatio-temporal
variabilities. Some new results have also been achieved in understanding the
atmosphere--ocean interaction and atmosphere--land interaction processes
that affect the variability of the EAM system. Based on recent studies, the
EAM system can be seen as more than a circulation system, it can be viewed
as an atmosphere--ocean--land coupled system, namely, the EAM climate
system. In addition, further progress has been made in diagnosing the
internal physical mechanisms of EAM climate system variability, especially
regarding the characteristics and properties of the East Asia-Pacific (EAP)
teleconnection over East Asia and the North Pacific, the Silk Road
teleconnection along the westerly jet stream in the upper troposphere over
the Asian continent, and the dynamical effects of quasi-stationary planetary
wave activity on EAM system variability. At the end of the paper, some
scientific problems regarding understanding the EAM system variability are
proposed for further study. |
