Question

Quizplus · Accepted Answer

Geostrophic circulation within a gyre is driven by gravity and the Coriolis effect. As water moves away from the center of the gyre due to the action of the wind, the resulting pressure gradient causes water to move back towards the center of the gyre, creating a circular flow. This circular flow is then affected by the Coriolis effect, which causes water to move to the right in the Northern Hemisphere and to the left in the Southern Hemisphere, resulting in a clockwise rotation in the Northern Hemisphere and counterclockwise rotation in the Southern Hemisphere. Density, temperature, pressure, and salinity may affect ocean circulation, but they are not the primary drivers of geostrophic circulation within a gyre.
