  THE ROLE OF AIR-SEA INTERACTION IN THE EVOLUTION OF THE ASIAN SUMMER MONSOONS: CLIMATOLOGICAL ASPECTS AND INTERANNUAL VARIABILITY

The essential physical processes associated with the Asian monsoon are reviewed. Efforts to simulate this circulation system using numerical models are described. The distinct characteristics of the space-time evolution of the climatological monsoon in the western North Pacific-South China Sea (WNP-SCS) and Southern Asia (SA) sectors are presented, with particular emphasis on the role of air-sea interaction in such development. The year-to-year variations of the timing of the summer monsoon onsets over the WNP-SCS and SA, and their relationships with the remote and local sea surface temperature anomalies associated with El Nino episodes in the tropical Pacific, are examined using model experiments.
