6B.1
Tropical convection and surface wind convergence using spacebased data
W. Timothy Liu, JPL, Pasadena, CA; and X. Xie
Tropical convection exhibits complex spatial and temporal structures from daily cloud clusters, to intraseasonal Madden Julian Oscillation. They may have profound influence in annual (e.g., monsoon) to interannual (El Nino) changes. Between April and October 2003, two spacebased scatterometers on QuikSCAT and ADEOS-2 provided high resolution sampling of ocean surface wind convergence and the precipitation radaor (PR) on the Tropical Rain Measureing Mission (TRMM) provide precipitatio / heating profiles. The relation between deep convection, and surface wind convergence and sea surface temperature are being examined in the tropical Pacific and Indian ocean, to shed light on the hypotheses of the onset of monsoon and El Nino.
