A study of tropical instability waves over the atlantic using a coupled regional atmosphere-ocean model Conference Paper uri icon


  • The preliminary results in this study show that near ITCZ the air-sea interaction mechanisms of tropical instability waves may be further investigated through realistic simulations performed by the coupled atmosphere-ocean model (RCM-RGO). Some defects of the simulated results may be improved by performing the model simulation far beyond the spin-up period of the coupled model. To improve the modeled background climatologies of the atmosphere and the ocean, numerous experiments need to be conducted with various parameterization adjustments in both RCM and RGO. Some studies have suggested that surface wind forcing may control the ocean instability waves to some extent, suggesting that the instability waves in the atmosphere may also affect the evolution of SST perturbations. A diagnosis of the energetics of these instability waves may provide more insights to the main air-sea interaction mechanisms of these waves in the ocean and the atmospheric boundary layer.
