Abstract

The interaction of a polar trough with a polar front can lead to a characteristic satellite cloud pattern commonly referred to as an instant occlusion. The AA. refer to it under the name of pseudo-occlusion. A conceptual model of the pseudo-occlusion is developed in which the key elements are (1) a moist, relatively warm, low-level jet associated with the polar trough, and (2) a major upper-level jet streak associated with the polar front. The polar trough conveyor belt and the polar front conveyor belt intersect almost at right angles. They are both generating their own distinct areas of precipitation. (JPB).
