The export of these water masses varies across models, with most overestimating the total transport. Correlation coefficients between the air-sea fluxes and exports are consistent with theoretical ... thomas ppa hubWebFig.2 The Ekman transport is directed perpendicular to the applied stress (to the right if Ω > 0, to the left if Ω < 0) driving (left) convergent flow if the stress is anticyclonic and (right) divergent flow if the stress is cyclonic. … uil 300 batteryWebIt was moving consistently to the right of the wind direction. This phenomenon would later become known as Ekman transport. As wind blows across the ocean, it moves water because of friction at the ocean surface. Because the Earth rotates, surface water moves to the right of the wind direction in the Northern Hemisphere and to the left of the ... ui know howWebIn (a) there is a divergence at the surface which depresses the surface of the ocean and raises water from beneath the thermocline towards the surface (upwelling).
