Tropical convection during the onset of two Madden-Julian oscillation (MJO) events, in October and December 2011, was simulated using Weather Research Forecasting (WRF) Model. Observations from Dynamics MJO (DYNAMO) field campaign were assimilated into WRF Model for an improved simulation mesoscale features tropical convection. The simulations with assimilation DYNAMO data produced realistic representations related to westerly wind bursts (WWBs) as well downdraft-induced gust fronts. An end-to-end simulator (E2ES) Cyclone Global Navigation Satellite System (CYGNSS) mission then applied dataset, producing CYGNSS near-surface speed data. results indicated that could detect such WWBs fronts even presence heavy precipitation. This study has primary conclusions a consequence: 1) satellite simulators be used examine mission's capabilities accomplishing secondary tasks 2) likely will provide benefits future oceanic campaigns should considered their planning processes.
