Abstract

The sea surface imprint of atmospheric vortex streets (AVS) observed on a RADARSAT SAR image of the Aleutian Islands in the western Gulf of Alaska acquired on December 22, 1999, is analyzed. The AVS is interpreted as the atmosphere analog of classic Von Kluman vortex streets. The AVS length is about 220 km. There are several pairs of vortices within the AVS. The vortex shedding period is estimated to be about 36 minutes. The vortex tangential velocity and the energy dissipated during the vortex lifetime are estimated using the Von Karman vortex streets theory.
