Sea surface temperature (SST) is a major factor affecting the intensity of tropical cyclone (TC). The SST is not fixed, but decreasing during the passage of TCs due to a strong vertical mixing and upwelling. The TC-induced sea surface cooling along the track, called as "cold wake", plays a critical role in reducing the TC intensity. Here, we simulated the cold wake, a product of the air-sea interaction, during typhoon Bolaven in 2012 using a WRF-ROMS coupled model. Initial fields of WRF and ROMS are obtained from GFS and HYCOM global models, respectively.
