MISO-BOB atmosphere-ocean interactions

Abstract

Intraseasonal variability of the atmospheric circulation affects the timing and severity of weather in the Asian monsoon, and the sa,fety of assets and persons at sea. Boreal summer intraseasonal weather anomalies propagate northward from the equatorial Indian Ocea,n across the Bay of Bengal. Including interactive sea surface temperature (SST) in this region improves intraseasonal forecasts. SST, anomalies affect both surface fluxes, and horizontal moist static energy convergence in the marine atmospheric boundary layer.The p,roposed project will1)provide surface meteorology, SST, and air-sea flux measurements from the research vessel deployed on the Monso,on Intraseasonal Oscillation - Bay of Bengal (MISO-BOB) intensive observation period (IOP).2)visualize, quality control, and analyze, MISO-BOB surface meteorology, flux, and rawinsonde observations.3)relate atmospheric intraseasonal monsoon oscillations to surface,meteorology, air-sea flux, and (measured by other MISO-BOB investigators) upper ocean conditions.In the salinity-stratified Bay of B,engal, air-sea fluxes strongly affect processes in the upper ocean, and these upper ocean processes affect SST. Observation of the a,tmosphere-ocean interactions in MISO-BOB will improve forecasts by offering more accurate representations of these processes for mod,els.
