Global Diurnal Rain Types in 3-D

While the overall rain might maximize at a certain time of day, different rain processes contribute to the evolution of that diurnal peak. Observations from the Tropical Rainfall Measuring Mission (TRMM) and Global Precipitation Measurement (GPM) spaceborne radars from 1998-2022 show a large diversity in the diurnal cycle of precipitation across the globe depending on the type of cloud producing the rain. This presentation will highlight the diurnal maxima in the geographical patterns and vertical echo distributions for the following rain types: shallow isolated convection, shallow non-isolated convection, deep convection, stratiform rain without bright band, and stratiform rain with bright band. Special note will be made for when extreme rain rates or echo heights occur and a brief comparison to the diurnal cycle of the convective and large-scale rain from a small subset of global climate models will be provided.
