A Greenland Sea perspective on the dynamics of postconvective eddies / K.I.C. Oliver, and 3 others.
Title: | A Greenland Sea perspective on the dynamics of postconvective eddies / K.I.C. Oliver, and 3 others. |
Author(s): | Oliver, K. I. C. |
Date: | 2008. |
In: | Journal of Physical Oceanography. (2008.), Vol. 38(12) (2008) |
Abstract: | Investigates key postconvective processes using numerical experiments of increasing sophistication with two goals: to understand how ambient hydrography and topography influence propagation of hetons (dipoles consisting of surface cyclone and weakly stratified subsurface anticyclone); and to provide theoretical context for recent observations of submesoscale coherent vortices in Greenland Sea. Finds that alignment of hetons is controlled by ambient horizontal density gradients and that hetons self-propagate into lighter waters. This provides mechanism for transporting convected water out of cyclonic gyre, but propagation is arrested if heton meets large-amplitude topography. |
