Document Summary
But not directly as currents flow at a 45 angle to the wind direction & like wind are deflected by coriolis force to the right or left. This curving increases with depth & at about 100m depth the flow is almost. 180 to that at the surface. this curvature of the ocean current with depth is known as the ekman spiral. * ocean currents will affect land temperatures based on the t of the current: * a warm current will keep the land area a little warmer in winter and a cold current will often keep the land area a little cooler in summer. * they will also influence precipitation amounts and patterns as well. Warm currents usually result in higher precipitation amounts and cold currents usually result in lower amounts, but this can be complex. Upwelling is the vertical movement of water within the ocean from great depths to the surface.
