Previous studies have shown that the interaction between the MJO and high frequency waves (HFW) can promote the eastward propagation of the MJO convection and zonal wind. In this talk, I will discuss the two-way interaction between MJO and HFW over the MC region with the MJOTF/GASS models’ data. The models are chosen into good and poor model groups according to their capabilities in simulating the eastward propagation of the MJO convection and flows. The differences of the modulation of the HFW by the MJO, the upscale feedback from the nonlinear rectification of the intraseasonal condensational heating, and the upscale feedback from the eddy momentum transport between the good and poor model groups will be compared. The results exhibit that the variation of the HFW contributes to the eastward propagation of the MJO convection. However, the eastward propagation of MJO zonal wind is mainly related to simulation of the MJO flows.
