Abstract

In this paper, the ROMS model was used to simulate the sea surface temperature (SST) in the central region of Vietnam’s East Sea. Two turbulent closure schemes: Brunt-Vaisala and KPP were applied with the same conditions in order to compare the differences and the ability for using them. The simulated SST fields were compared and in good agreement with the mechanism maps of SST. The suggestions for using these schemes were analyzed. This result raises a question and answers how to choose a better closure scheme to apply in simulating SST. The solved problem is very necessary for applying numerical models to simulate SST field.
