Convective clouds play an important role in redistributing heat and moisture and drive large-scale circulations, yet Earth system models are plagued by their inadequate representation. The June 2022 Experiment of Sea Breeze Convection, Aerosols, Precipitation, and Environment (ESCAPE) utilized the National Research Council (NRC) of Canada Convair-580 and Stratton Park Engineering Company (SPEC Inc.) Learjet near Houston, Texas and high-resolution radar observations to study the influences of aerosols and meteorology on the evolution of isolated convective cells. The interaction of onshore flow and sea-breeze convection and the range of aerosol conditions associated with Houston’s urban and industrial emissions make it an ideal location for studying the competing effects of aerosols and meteorology on convective evolution. During ESCAPE, 13 flights of the NRC Convair-580 and 11 flights of the SPEC Learjet were performed in a variety of meteorological and aerosol conditions. Observations in cleaner conditions over the Gulf of Mexico, in polluted conditions near or downwind of refineries east of Houston, and in less polluted conditions west of Houston were obtained as well as in updrafts as large as 29 m s-1. Radars on the NRC Convair-580 and SPEC Learjet characterize the context of the cloud microphysical properties, such as the liquid water content, total number concentration, effective radius, maximum particle size, extinction and number distribution functions, which are derived from aircraft in-situ probes. This presentation describes how these parameters vary with aerosol content, updraft velocity, and meteorological conditions. Implications for understanding indirect aerosol effects will be discussed. |
