WEATHER CONDITIONS ASSOCIATED WITH THE PASSAGE OF PRECIPITATION TYPE TRANSITION REGIONS OVER EASTERN NEWFOUNDLAND

The passage of a winter storm is accompanied by changes in many surfac e and near-surface parameters including temperature, humidity, wind pr essure, precipitation rare and type, cloud base height, visibility and accretion. These parameters were measured in association with the pas sage of precipitation-type transitions over Newfoundland during the Ca nadian Atlantic Storms Program II field experiment. Three simple summa ries of the observed weather events were developed. These summaries de pend on the observed large-scale synoptic conditions, which include wa rm fronts, a cold front and a trough.
