Back-Bent Occlusion

Published: 01 January 2005

The concept Back Bent Occlusion refers to a part of a warm occluded front that changes its direction of motion and turns into a Cold Front. This back bending is due to remarkable cold air advection at the rear side. The bending back of an occluded front can be seen from the curvature of TFP field around the Occlusion.The surface pressure gradient is relatively weak near the centre of the low, and often elongated in the direction of the occluded front.
