Underestimation of latent and sensible heat fluxes above the Agulhas Current in NCEP and ECMWF analyses

From: Journal of Climate | Date: February 15, 2003| Author: | Copyright information

ABSTRACT

The Agulhas Current is the major western boundary current of the Southern Hemisphere. South of Africa it retroflects back into the southwest Indian Ocean, transporting relatively warm water into the midlatitudes. Large sensible and latent heat transfers from the Agulhas Current and its retroflection to the atmosphere occur throughout the year, but particularly during winter. This study suggests that the NCEP and ECMWF models tend to underestimate these fluxes because they are unable to adequately represent the air-sea fluxes over the warmest waters in the core of the current. This ...
