Rotation Air is pulled inward by the low pressure. The Earth's rotation deflects wind to the right, causing the storm to rotate counterclockwise. Winds pick up Surface wind accelerates near the storm's center and is warmed by contact with the sea. The storm begins feeding on itself, using the evaporated warm water as additional energy. This causes pressure to drop at the surface, pulling in more air and strengthening the storm.
Some air sinks back into the center, warming it and creating the nearly cloud-free eye.
