10.15 Annual and Interannual Variabilities of East Asian Monsoon Revealed by Spacebased Observations

A signi cant portion of the world's population is under the in uence of monsoon changes. Understanding of physical processes governing the evolution of Asian monsoon is not only important for regional climate variation, but also crucial to global climate variation. Besides bringing rain to land, monsoons also change ocean currents, ocean upwelling, and coastal ecology. Over land the consequences of monsoon are, perhaps, well observed, but the ocean observations are still very sparse. Spaceborne microwave scatterometers and radiometers observe ocean surface with high spatial and temporal resolution, which provides an unprecedented opportunity to explore variability at the sea surface on various time scales.
