Document Summary
5 subtropical gyres driven by windbelts centered around 30 degree latitude 1. Gyres: large circular loops of moving water driven by major wind belts. Equatorial: travel westward along equator, moved by trade winds, north and south. Western boundary-(intensified, fast, narrow, deep, warm) western side of the ocean basin, carries warm waters from equatorial regions, flows toward high latitudes due to coriolis and continents. Norhtern or southern boundary: easterly water flow across ocean basin due to westerly winds, northern boundary currents in n hemi, southern boundary currents in s. hemi. Eastern boundary(cold, slow, shallow,wide) on east of ocean basins, carry cool waters to lower latitudes, flows toward low latitude due to coriolis and continents. Moves to right in northern hemi and the left in the southern hemi. Describe the speed and direction of flow of water at various depths. Ekman transport is average movement of surface waters (90 degrees right in n. hemi or left in s. hemi)
