The objective of this study is to identify factors that may influence the propagation of Kelvin waves and the MJO across the Maritime Continent. Our data are derived from Climate Forecast System reanalysis and reforecasts and NASA satellite products (TRMM, GPM IMERG). In this ongoing work, we examine how the diurnal cycle of convection over the Maritime continent interacts with equatorial waves and provides an upscale feedback to the MJO. We also examine how horizontal moisture advection, which has been shown to be important for MJO propagation, may be disrupted by the presence of major islands within the Maritime continent. Results from these investigations will be presented at the conference.
