Abstract


In this paper identified many years monsoon onset monsoon index based on wind shear ; calculated using the measured data of the 2008 monsoon onset characteristics of the front and rear air-sea fluxes ; COARE3.0 algorithm reanalysis data with NCEP2 in air-sea elements calculated air-sea heat flux field compared with NCEP2 original heat flux field ; spatial and temporal characteristics of the monsoon outbreak sooner or later, the Year of the air-sea heat flux field ; using the EOF method using SVD method analysis of the heat flux field and sea temperature field and the relationship of the monsoon , and explore the process and mechanism of the air-sea heat flux changes affect the monsoon onset . The results show that : 1,2008 SCS summer monsoon onset during tropical cyclone on the influence of the elements of the air-sea . Momentum exchange coefficient of heat exchange coefficient is a function of the wind speed , the curve at a wind speed of 4m / s when a turning point in the process . 2 , changes in sea surface temperature ahead of the monsoon onset time and intensity variations ; ahead of the heat flux changes in sea surface temperature changes . Heat flux through the the SST intermediate process to produce an effect on the monsoon . 3 , the monsoon onset and intensity changes by 2-3 months when pre Kuroshio heat flux change . The waters of the heat flux greater when subsequent partial early monsoon onset , the strong side ; Conversely , the monsoon outbreak migraine night , weak .
