| Research Abstract |
We attempted to evaluate the role of the coastal upwelling for the change of the sea surface temperature (SST) in Warm Water Pool, by using the products of the 4 dimensional variational data assimilation technique (4DVAR) and the observation records. We found that the change of the SST in the coastal areas could play a significant role for the large scale phenomena such as El Nino Southern Oscillation (ENSO) or the Indian Ocean Dipole Mode (IOD) at interannual time scales, as the local air-sea coupling processes can have an effect as a trigger, e.g., the relationship between the coastal upwelling and the resultant atmospheric convective adjustment.
