Circumpolar response of Southern Ocean eddy activity to a change in the Southern Annular Mode

Meredith, Michael P; Hogg, Andrew

Description

Analysis of satellite altimeter data reveals anomalously high Eddy Kinetic Energy (EKE) in the Antarctic Circumpolar Current (ACC) during the period 2000-2002. Around 2-3 years earlier (1998), the circumpolar eastward wind stress (as quantified by the Southern Annular Mode; SAM) showed a significant positive peak, and we have shown previously that the ACC peaked around 1998 in response. An eddy-resolving ocean model is used to investigate the delay between wind forcing and the eddy response,...[Show more]
