The long-term goal of our research program is to understand subseasonal processes in the equatorial Indian Ocean, with the goal of contributing to improved prediction of atmospheric and oceanic weather of the Indian Ocean IO and beyond. The strong ocean-atmosphere coupling in the region and its role in worlds climate have prompted detailed observations on either side of the sea surface, covering a swath of scales and interactions. Capturing subseasonal variability of key signals carried by oceanic currents and atmospheric circulation, and delineating their role in phenomena of significance, will be of interest. Some examples include Madden Julian Oscillation MJO, planetary waves, transients of Hadley circulation, Kelvin-Rossby wave packets in the atmosphere and the seasonally reversing current systems and upwelling in the ocean, all of them are strongly coupled. It is hypothesized that smaller scale processes such as convection in the atmospheric boundary layer and turbulent entrainment, which have received scant attention hitherto in the context of larger scale processes, play a key role. Thus, coupled observations are of primary interest. Close partnerships with IO countries are sought to help develop integrated research programs, and enlisting of other US agencies such as National Oceanic and Atmospheric Administration NOAA, Army Research Laboratory ARL and Naval Research Laboratory NRL is highly perused with respect to instrument deployment, regional atmosphere-ocean coupled model simulations and capacity building of partnering countries.
