Abstract
The long-term goal of our research program is to understand small to synoptic scale processes in the northern and equatorial Indian Oceans, with the goal of contributing to improved prediction of atmospheric and oceanic conditions (weather) of the Indian Ocean (IO) and beyond. Strong ocean - atmosphere coupling in the region calls for detailed observations on both sides of the sea surface , covering relevant 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, planetary waves, transients of Hadley circulation, Kelvin - Rossby wave packets in the atmosphere and the seasonally reversing current systems and upwelling patterns in the ocean, all of them are perceived to be coupled. It is hypothesized that smaller scale processes such as convection and turbulent entrainment , which have received scant attention hitherto, can play a key role in the dynamics of processes at larger scales, which needs to be delineated. Observations covering critical elements such as Bay of Bengal (BOB) circulation, East India (and Sri Lanka) current, internal and planetary wave propagation as well as capturing atmospheric convection and circulation in a swath of the equatorial IO are expected to contribute immensely to the understanding of regional weather and its global impacts. Collaboration on the conduct of regional atmosphere - ocean coupled model s using a suite of platforms is also a goal.
