| Abstract: |
| Based on the observations,the location and the strength of warm(cold) anomaly of SST in summer are controlled mainly by the subtropical highs of atmosphere(typhoon track) on the offshore of the China seas.It may be considered from the physical causes that the factors forming O-SSTA include the dynamic response of upper layer ocean on the strong atmospheric forcing and the shallow sea effects.The former consists of the entrainment,the detrainment,the Ekman pumping and the convergence of surface warm water; the later the tidal mixing and higher absorptivity.The parameterized expressions and the significance estimations of each factor are shown.The differences of both forming mechanisms and forming time-scales between the warm anomaly and the cold one are also indicated with different forcing svstemv. |
