"WebA coastal downwelling is the opposite of a coastal upwelling. Warm surface water can be blown towards the shore by Ekman transport. This warm water mass pushes cold water down and away from the shore. Another kind of downwelling occurs when there is a buildup of the water in the center of a hurricane or in other low-pressure centers. " - How does an upwelling and a downwelling form
