cutting-off process

A sequence of events by which a warm high or cold low, originally within the westerlies, becomes displaced either poleward (cut-off high) or equatorward (cut-off low) out of the westerly current.

This process is evident at very high levels in the atmosphere; it frequently produces, or is part of the production of, a blocking situation.
