Abstract:

The South Asian monsoon \, a coupled ocean-atmosphere feature of the Northern Indian Ocean (Bay of Bengal and Arabian Sea)\, is one of Earth's great heat engines. Its upper ocean is a natural laboratory for how small-scale physics shapes large-sc ale weather patterns. Strong river-driven freshwater input\, very thin mix ed layers\, and the twice-yearly wind reversal combine to make this a regi on where mixing\, submesoscale fronts\, and air-sea interaction all matter \, and where a one-dimensional view of the ocean breaks down. These proces ses are not well represented in our weather prediction models. This introd uces errors in the South Asian monsoon predictions\, which degrade forecas ts globally on a 7-to-10-day timescale. Improving intraseasonal forecasts globally requires a focused multi-national scientific effort.

This talk traces more than a decade of collaborative field programs in these t wo basins\, including ASIRI-OMM\, MISO-BoB\, and the ongoing EKAMSAT\, spa nning ship\, mooring\, glider\, and autonomous-platform observations throu gh to the models they inform. I will show how freshwater sets the stratifi cation and suppresses mixing\, how fronts and filaments restratify the upp er ocean at rates comparable to air-sea fluxes\, and why these processes b ias the sea surface temperature and mixed-layer depth that monsoon forecas ts depend on. I will close with current work in my lab\, including eddy tr ansport of heat and salt\, near-inertial waves at curved fronts and shield ed eddies\, evaluation of reanalysis products and ocean models\, and the A urelia profiling vehicle\, together with where we are headed next.
