Nested Modeling Studies in the Northwest Atlantic

Studies are underway in a variety of nested regions within the Northwest Atlantic, as shown in Figure 2. The scientific and technical issues addressed in these studies include a better understanding of regional processes (wind-driven upwelling and associated bio-optical response, surface boundary layer dynamics under low wind speed conditions, material transport within buoyancy-driven plumes, etc.) as well as the development of data-assimilative regional prediction systems.
As one component of these ongoing studies on the Northwest Atlantic shelves, we are developing realistic simulations of shelf circulation, mesoscale events, and interannual variability associated with major climate modes such as the North Atlantic Oscillation. This will be achieved by improving the basin-scale embedding procedure to use results from the PARADIGM modeling effort (http://www.gso.uri.edu/paradigm/), and the retrospective North Atlantic eddy-resolving models of the Mercator (www.mercator.com.fr) and HYCOM (hycom.rsmas.miami.edu) groups that assimilate satellite altimetry, sea surface temperature, and Argo float profiles. This will impose observed weekly to interannual time scale variability (predominantly from altimetry) on the physical circulation.
