Flow around steep topography
Abstract
Rapid, high-resolution spatial surveys will be made with Seasoar and with R/V Revlle s Doppler sonars, where major low-latitude zonal currents, such as the North Equatorial Current (NEC) and the North Equatorial Countercurrent (NECC), impinge on steep topography in the western Pacific. When the extent of the topography is larger or smaller than the deformation radius, the topographic effects on circulation are different. Going from large to small scales, I will: (1) Assess the incident mean/eddy flow and the WBC at a large island in relation to local or remote forcing; (2) Measure persistent submesoscale features (i.e., island-driven upwelling, turbulent wakes, and locally-generated eddies) around small islands; (3) Observe lee wave generation where a strong current impinges on a tall, steep submarine ridge.
