Research
To Improve and develop the simulation of MJO in CAM5-SIT and TaiCAM-SIT: Accurate simulation of MJO has always been a major uncertainty in the development of climate models. It is shown that the coupling of SIT into TaiCAM or CAM5 greatly improves the original MJO simulation of TaiCAM or CAM5, especially when the wavenumber-frequency occurs in the intra-season period and a lag correlation in zonal wind (U850) and precipitation anomalies.
The influence of upper ocean on MJO: In the previous study, we found that the impact of MJO is not limited to ocean area with MJO propagating (between Indian Ocean and the western Pacific). The upper ocean from the Central Pacific to the Eastern Pacific plays a key role in the trend and amplitude of MJO eastward propagation. In order to realize how did the interaction between the atmosphere and the ocean, TaiESM-SIT would be further used for area sensitivity testing by analysis atmospheric field (OLR, PREC, surface net radiation (NRF), evaporative latent heat (LHF), vertical wind speed (Omega) and humidity field convergence divergence (Divq)) and the ocean (SST and SST profile) spatial distribution. Finally, the study find the rules of favorable ocean conditions for MJO development.
