Mesoscale variability in Denmark Strait: The PV Outflow hypothesis / Michael A. Spall, James F. Price.
Title: | Mesoscale variability in Denmark Strait: The PV Outflow hypothesis / Michael A. Spall, James F. Price. |
Author(s): | Spall, Michael A. Price, James F. |
Date: | 1998. |
Publisher: | Boston, MA: American Meteorological Society |
In: | Journal of Physical Oceanography. (1998.), Vol. 28(8) (1998) |
Abstract: | Outflow is very variable on mesoscale, with continuous formation of cyclones just south of sill, with diameters of 30 km and clear signatures at surface and near bottom. Their core is Arctic Intermediate Water. Authors surmise that they are formed by stretching of high potential vorticity water column flowing out. Light upper layer, East Greenland Current, stays on top of Irminger Sea, while dense overflow water descends continental slope, stretching intermediate waters by more than 100%. Hypothesis was tested by numerical experiments on model. Cyclones produced are roughly consistent with reality. |
