You must log in or register to reply here. Changes in the structure of the eye and eyewall can cause changes in the wind speed, which is an indicator of the storm's intensity. However, as the speed increases, an outward-directed force, called the centrifugal force, occurs because the wind's momentum wants to carry the wind in a straight line. Why there are no thunder and lightning during a snowstorm? Daniel J. Kirshbaum, George H. Bryan, Richard Rotunno, and Dale R. Durran (2006). Actually, the storm is only half over with dangerous eyewall winds returning shortly, this time from the opposite direction.
