Climate—Boundary Current Interactions: Stories from East and West

  • Room 112, O&M Building (map)

Abstract

There is growing evidence that the large-scale climate affects character of oceanic boundary currents and by extension their ecosystems.  In this talk, I will present results from climate model integrations with a multi-scale ocean component capable of locally enhancing resolution.    The model is based on the NCAR Community Earth System Model (CESM), in which the ocean component contains a high-resolution ROMS nest. I will show results from implementations in the California Current System, the Benguela and the northwest Atlantic.  Results from the latest century-long integrations indicate that the better representation of coastal currents has both regional and global ramifications to the climate system.   Furthermore, I will show how the ocean-atmosphere coupled response differs from the one-way forced dynamics, which has implications to both the physics and ecosystems of coastal regions.
