- Cloud types, TCu with warm rain. A bank of large tropical convection Cumulus Congestus clouds is dropping heavy showers. A high freezing level and deep, moist air mass allow the cloud to build to a modest height without any upper parts freezing. Despite this, condensation is prolific and droplet coalescence rampant, forming heavy downpours of warm rain since the water droplets do not originate from melting ice crystals as with regular rain.
