We conducted cloud‐resolving simulations with two domain sizes and progressively reduced rain evaporation in the PBL. Surprisingly, CSA only occurred when rain evaporation was almost completely removed. The additional convective heating resulting from the reduction of evaporative cooling in the moist patch was found to be the trigger, thereafter a dry subsidence intrusion into the PBL in the dry patch takes over and sets CSA in motion. Temperature and moisture anomalies oppose each other in their buoyancy effects, hence explaining the need for almost total rain evaporation removal. We also found radiative cooling and not cold pools to be the leading cause for the comparative ease of CSA to take place in the larger domain."}],"oa":1,"year":"2024","day":"19","language":[{"iso":"eng"}],"author":[{"id":"1217aa61-4dd1-11ec-9ac3-f2ba3f17ee22","full_name":"Hwong, Yi-Ling","orcid":"0000-0001-9281-3479","last_name":"Hwong","first_name":"Yi-Ling"},{"orcid":"0000-0001-5836-5350","last_name":"Muller","first_name":"Caroline J","id":"f978ccb0-3f7f-11eb-b193-b0e2bd13182b","full_name":"Muller, Caroline J"}]}
