Global Winds Global winds are affected by their latitude and the Coriolis Effect. In the tropics winds blow from the east to the west. In more temperate areas, the winds blow from the west to the east. Near the poles the winds blow from the east to the west. Tradewinds Westerlies Polar Easterlies
Oceanic convection Creates: Deep ocean currents: fast moving currents of water. Gyres: a large system of rotating ocean currents caused by wind and the Earth’s rotation. Gulf stream: a powerful, warm, and fast Atlantic ocean current.
DeepOcean Currents Deep Ocean Currents Deep cold currents move water toward the equator. Cold water rises to replace warm water leaving. Warm water travels near the surface toward polar regions. Warm water replaces cold water.
Gyres A circular system of ocean currents rotating clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere; vortex.
Gulf stream A warm ocean current carrying heat north along the Atlantic ocean. Affects the climate of America and both northern and western Europe.
Global Forces Coriolis effect: deflection of wind and ocean currents due to the rotation of the earth. Continental deflection: deflection of wind and ocean currents due to continents (land). Deflection: to bend or turn.
