Record #177014:

Sea surface temperature variability along the path of the Antarctic Circumpolar Current / Ariane Verdy, John Marshall, Arnaud Czaja.

Title: Sea surface temperature variability along the path of the Antarctic Circumpolar Current / Ariane Verdy, John Marshall, Arnaud Czaja.
Author(s): Verdy, Ariane.

Date: 2006.
In: Journal of Physical Oceanography. (2006.), Vol. 36(7) (2006)
Abstract: Investigates spatial and temporal distributions of sea surface temperature (SST) anomalies in Antarctic Circumpolar Current (ACC) using monthly data from NCEP-NCAR reanalysis for period 1980-2004, and assesses role of ocean dynamics and atmospheric forcing with particular reference to El Niño Southern Oscillation (ENSO) and Southern Annular Mode (SAM). Identifies patterns of atmospheric forcing in observations of sea level pressure and air-sea heat fluxes, and shows that significant fraction of SST variability in ACC can be understood as linear response to surface forcing by SAM and remote forcing by ENSO. Simple model suggests that surface heat fluxes and Ekman heat advection are equally important in driving observed SST variability, with further diagnostics indicating that SST anomalies generated mainly upstream of Drake Passage are subsequently advected by ACC and damped after a couple of years. Results suggest that SST variability along path of ACC is largely passive response of oceanic mixed layer to atmospheric forcing.
