We consider the motion of a sporadic E layer initially located at the top of the E region near the node of the north-south component of the tidal wind. We find that, as the layer descends to follow the phase progression of the winds, the relative enhancement of the importance of the cast-west wind component can erode the layer trapping mechanisms til at some instant it fails, and the layer is freed. Thereupon it moves with a much greater vertical velocity than it did formerly until it reaches a new trapping location. (auth)
