We have examined geographical distributions, and seasonal and annual variations, of occurrences of freezing precipitation (rain and drizzle) and ice pellets, by using Japan Meteorological Agency surface meteorological data for the past 14 winter seasons (November 1989-May 2003). In Japan, these precipitation types have often occurred for the period January to March, and are observed about ten times every winter. Freezing rain falls only a few times each season, mostly from December to January.<BR>Most of the freezing rain and ice pellets occur in the inland ravines in the northern Chubu region, and in plains on the Pacific Ocean side of northern Kanto. The atmospheric condition when the freezing rain and ice pellets were observed in both regions was examined. As a result, it was found that local meteorology and geographical features strongly influence the formation of the cold air layer in which descending raindrops become supercooled in the vicinity of the ground. In inland ravines, a cold air reservoir within each basin plays an important role in the formation of the cold air layer near the ground. In the plains on Pacific Ocean side, in contrast, cold air drainage from inland peculiar to these plains contributed to forming the cold air layer. In addition, advected warm air layer melts snowflakes associated with the synoptic low-pressure system above the cold air layers providing the conditions required for freezing rain or ice pellets to occur.
