Basic purpose of this lecture is to present on Wind Direction of Ocean. A wind blowing for 10 hours across the ocean will cause the surface waters to flow at about 2% of the wind speed. Water will pile up in the direction the wind is blowing. Gravity will pull the water down the “hill” or pile of water. But the Coriolis Force causes the water to move to the right (in the northern hemisphere) around the mound of water.
