[IIOE2-EP02] Air-sea interactions in the Northern Indian Ocean: Regional initiative (ASIRI)
Lead investigator and other key participant(s):
- Dr. M. Ravichandran, INCOIS, Hyderabad, India
- Prof. Debasis Sengupta, IISc, Bengaluru, Indiaa
Period of Project: 2013-17
Brief description of the Project:
This is a five-year (2013-17) international collaborative research initiative by scientists and researchers from over 20 institutions and Universities in India, the US and Sri Lanka. The primary objectives of this initiative are:
- To understand and quantify dynamical processes and boundary transports that control fresh and salt water exchanges between the Bay of Bengal and the Arabian Sea;
- To observe small- to large-scale atmospheric phenomena that modulate air-sea exchanges and upper ocean heat content; and
- To examine the responses to buoyancy and wind stress forcing using high-resolution air-sea coupled models of both the processes and forecast-types.
Three long-term programmes are in-built into the ASIRI: the Ocean Mixing and Monsoons (OMM), focusing on improving the predictive monsoon models through study of air-sea fluxes and upper ocean processes; effects of Bay of Bengal Freshwater Flux on Indian Ocean Monsoon (EBOB) which focuses on the dynamics of freshwater, upper ocean processes, and air-sea interactions ("Coupled physical processes in the Bay of Bengal and monsoon air-sea interaction"); and Remote Sensing of Atmospheric Waves and Instabilities (RAWI) which seek to monitor atmospheric waves, instabilities, and turbulence by deploying remote sensing arrays on island nations across the equatorial Indian Ocean. As a part of the ASIRI-OMM-EBOB initiatives, the first cruise endorsed by IIOE-2 was taken up on board the Indian Research Vessel Sagar Kanya between 23 January and 08 February 2016.
