Rain‐snow boundaries and freezing precipitation in canadian east coast winter storms

Abstract

Fourteen rain‐snow boundaries and freezing precipitation episodes within Canadian East Coast winter storms are examined. Radar, sounding, and surface observations are used to study the characteristics of these features. Rain‐snow boundaries and freezing precipitation episodes are coupled phenomena. The deepest radar echoes and the heaviest precipitation generally occur in the adjacent snow region, and surface wind shifts typically are associated with the transition to rain. © 1988 Taylor and Francis Group LLC.
