Abstract
Coastally associated rainfall is a common feature, especially in tropical and subtropical regions. However, it has been difficult to quantify the contribution of coastal rainfall features to the overall local rainfall. The authors develop a novel technique to objectively identify precipitation associated with land-sea interaction and apply it to satellite-based rainfall estimates. The Maritime Continent, the Bight of Panama, Madagascar, and the Mediterranean are found to be regions where land-sea interactions play a crucial role in the formation of precipitation. In these regions ~40%-60% of the total rainfall can be related to coastline effects. Because of its importance for the climate sys..
