ON THE SUPERCOOLED DRIZZLE OBSERVED AT INUVIK IN THE MID-WINTER SEASON (WANTS-ARCTIC; CANADA)

Supercooled drizzle was observed at Inuvik, N. W. T., Canada (68°22′N, 133°42′W) on December 20,21 and 27,1995. Meteorological conditions in which the supercooled drizzle could form under low temperatures in the mid-winter season of Arctic Canada were examined from the sounding data and data measure...

Description
Summary:Supercooled drizzle was observed at Inuvik, N. W. T., Canada (68°22′N, 133°42′W) on December 20,21 and 27,1995. Meteorological conditions in which the supercooled drizzle could form under low temperatures in the mid-winter season of Arctic Canada were examined from the sounding data and data measured by a passive microwave radiometer at ground level. The following results were obtained : 1) Supercooled drizzle fell to the ground with ice pellets and frozen drops on snow crystals. 2) The maximum size of supercooled drizzle particles increased as the depth of cloud layer saturated with respect to water increased. 3) Because a layer of air temperature higher than 0℃ was not detected from the sounding data at Inuvik, melting of snow particles was impossible. It was concluded, therefore, that supercooled drizzle was formed by the collision-coalescence process below freezing temperature.
