Long term trend of sea surface temperature in the South China Sea
Using the Hadley Centre Global Sea Ice and Sea Surface Temperature (HAdISST) the long term trend in the South China Sea (SCS) sea surface temperature (SST) between 1950 and 2008 is investigated.In general SST has been increased since 1950,but the rate of increase is spatiotemporally uneven.Temporally winter warming rate is greater than that of summer.In addition the rate of increase is greater during 1980s.Spatially during winter warming rate is greater in the deep basin and during summer over the southeastern SCS.To find the cause of the warming winds and air-sea heat fluxes are also analyzed.In summer the weakening of southwesterly monsoon reduces upwelling east of Vietnam to warm the surface.On the other hand,the net surface heat flux,however,is reduced and cannot contribute to the warming.In winter the net heat flux into the sea increases and could contribute to the warming.The spatial pattern of the heat flux,however,is different from that of the warming.The heat flux is increased over the coastal area where warming is small,but decreased in deeper part where warming is greater.After 1980s the northeasterly monsoon winds weakens to reduce the southward western boundary currents,and subsequently cold advection.The decreasing cold advection by changing ocean currents in particular plays an important role in the SST warming.
