PL24B:
New Insights into the Dynamics of the Western Tropical Indian Ocean II Posters


Session ID#: 27486

Session Description:
The circulation in the western tropical Indian Ocean is driven by monsoonal forcing leading to seasonally reversing currents as well as vigorous coastal upwelling and (sub)mesoscale activity, particularly in the Arabian Sea. Regional water masses are created and modified through a combination of extreme air-sea interactions and upper-ocean mixing processes, which may feed back on the Indian monsoon itself. This session will highlight new insights into the physical and biogeochemical interactions of all major western tropical Indian Ocean areas including the Arabian Sea, the Red Sea, the Mozambique Channel, and the Seychelles-Chagos thermocline ridge. Abstracts are also solicited on the connectivity of the western tropical Indian Ocean to adjacent seas such as the Bay of Bengal and the Agulhas region. In particular, we seek contributions that emphasize the use of combined components of the global ocean observing system (including in situ and autonomous measurements as well as remote sensing), innovative standalone observations, or model studies of varied complexity to elucidate the dynamics of the circulation in the western tropical Indian Ocean, the coupled ocean-atmosphere interactions, and the connection to the Indian monsoon variability.
