Air flow in both the northern and southern hemispheres differ depending on the effects that occur. Air has a tendency to move slightly to the right due to the Coriolis effect. So, the air will flow clockwise. The same is true for water. In the ocean, the water may swirl or turn clockwise for the bodies of water located in the northern hemisphere. When the air is being pushed down, it will turn counterclockwise due to the high pressure.
When a hurricane occurs, the water will turn in a counter-clockwise pattern if this is occurring in the northern hemisphere. The low air pressure may cause it to move in a counter clockwise pattern. High pressure and flow will cause the air to move clockwise.
