%X Comparing two assimilation data,GODAS(Global Ocean Data Assimilation System) and SODA(Simple Ocean Data Assimilation),the annual cycles of overturning circulation and meridional heat transport in the northern Indian Ocean simulated by LICOM(LASG/IAP Climate System Ocean Model) are evaluated.LICOM reproduces reasonably seasonal variability of large-scale circulation,and resolves the Southern Gyre and the Great Whirl around Somali in the southwest monsoon.Wind-driven meridional overturning circulation simulated by LICOM consists of a STC(southern overturning cell) and a CEC(cross-equatorial overturning cell).STC is stronger than CEC in the boreal summer while weaker in the boreal winter.The total circulation transport is about 16 Sv,whose maximum center lies at 100-200 m in the southwest monsoon and at 200-1000 m in the northeast monsoon.Annual mean cross-equatorial heat transport from LICOM is-0.24 PW,which is closer to the observation and assimilation data than numerical modeling results before.Vertical overturning circulation is the main contribution to the seasonal cycle of meridional heat transport.Meridional heat transport south of the Equator in the boreal summer in LICOM is 0.5 PW less than the assimilation data.This is related to weaker zonal wind stress of LICOM here,resulting in weaker Ekman heat transport and shallower meridional overturning circulation.
