The speed of the storm combines with the wind speed to create a net force, as the diagram below shows: The eye and rain bands of a hurricane are formed by rising and sinking motion within the dynamic motion of the storm. Half a century ago. Sea breeze front thunderstorm lines can become strong enough to mask the location of an approaching cold front by evening. The sharper the curvature, and/or the faster the rotation, the stronger is the centrifugal force. Such warming encourages the air to expand, setting up large pressure variations across the feeder band and encouraging the denser, rain-cooled surrounding air to rush in, helping produce the phenomenal winds of the hurricane. One way of looking at this is watching figure skaters spin. [9] Southwest of extratropical cyclones, curved flow bringing cold air across the relatively warm Great Lakes can lead to narrow lake-effect snow bands which bring significant localized snowfall.
