Sting Jets

The presentation will discuss the strong winds that are sometimes found in the southwest quadrant of a cyclone and which on occasion can cause damaging winds at the surface. A conceptual model will be presented showing how these winds are related to air streams in the cyclone. Evidence for a distinct airflow known as a \'sting jet\' will be presented - this is a descending jet of air reaching the top of the boundary layer a little behind the cold front. Reference will be made to results from recent experimental field campaigns to study this phenomenon.
