ABSTRACT :

Despite its importance for a variety of socio-economical and political reasons and the presence of extensive coral reef gardens along its shores, the Red Sea remains one of the most under-studied large marine physical and biological systems in the global ocean. This talk will present our efforts to build advanced modeling and forecasting capabilities for the Red Sea. Our Red Sea modeling system compromises regional and nested MIT general circulation models (MITgcm) with resolutions varying between 2km and 100m to simulate the general circulation at various spatial scales, forced with the outputs of a 10-5km resolution assimilative Weather Research Forecasting (WRF) model. State-of-the-art monitoring capabilities are being deployed in the Red Sea as part of SAMERCK, comprising multiple gliders equipped with hydrographical and biological sensors and HF surface current mapping, complementing available satellite ocean and atmospheric observations. Fully parallel ensemble Kalman-based filters have been implemented with the MITgcm and WRF for assimilating all available data sets. We have also developed advanced interactive visualization tools to explore and analyze the space-time variability of the assimilation products and their ensemble-based estimated distributions and uncertainties. This talk will first present our recent findings on the role of the Indian Monsoon in regulating the physical-biological variability in the Red Sea, and then present our assimilation and visualization systems.
