Impact of multiple-scale circulation interactions on the spring diurnal precipitation over Luzon

Abstract This study examines the spatiotemporal characteristics of diurnal precipitation over Luzon and the nearby oceans in boreal spring. The study focuses on exploring the impact of the interaction between large- and local-scale circulation changes on the modulation of diurnal precipitation. We a...
