  abstract = {{T}his study is an attempt to evidence the impact of the inundation occurrence on the deep convection at continental scale. {T}hree sources of satellite observations are carefully analyzed over the tropics for 3 years: {A} multisatellite wetland extent and dynamics data set, a deep convective activity index derived from passive microwave satellite measurements at 85 {GH}z, and precipitation estimates. {A}lthough many other effects contribute to the variability in the convection (e. g., large-scale circulation and weather regimes), careful examination of the seasonal and diurnal variations of the satellite-derived information makes it possible to observe two distinct regimes. {T}he first regime corresponds to regions where the inundation is not generated by local precipitation. {T}here it is shown that stronger convection happens during the minimum of the inundation, with a marked diurnal cycle of the deep convective activity. {S}imulations with a single-column model are in good agreement with these satellite observations. {F}irst, calculations show that during the season of minimum inundation, hydrometeors are present higher in altitude, increasing the likelihood of larger ice quantities aloft. {S}econd, the diurnal cycle of the convective activity related to the presence of large ice quantities has a larger amplitude. {T}he second regime corresponds to regions where the inundation is directly generated by local precipitation. {T}here our observational analysis could not isolate any effect of the inundation on the convection.},
