aquiclude
type of rainfall that occurs when air masses converge into a low pressure area resulting to their eventual ascension. A specific type of cyclonic rainfall is frontal precipitation, which involves the meeting of a warm and a cold front.
cyclonic precipitation
type of precipitation that occurs as a result of convective heating of the ground surface causing the warm and lighter air parcel to rise above the cold, denser surroundings thus causing the lifting of the air mass which consequently leads to precipitation
