Abstract: The Canadian Atlantic Storms Program (CASP) field project was conducted from 15 January to 15 March 1986 over Atlantic Canada in conjunction with the American Genesis of Atlantic Lows Experiment (GALE). The goals of CASP ...

Abstract: Winter storms often produce snow, freezing rain, and ice pellets. The characteristics and formation of these forms of precipitation as well as their location within storms are reviewed. Phenomena such as accretion and fog ...

Abstract: The NCEP?NCAR reanalysis data were used to calculate the atmospheric moisture fluxes into and out of the Saskatchewan River basin for the period 1948?2001. Although bias exists in the estimated moisture flux divergence, ...

Abstract: The mesoscale storm structure and the evolution of precipitation type are examined during freezing precipitation episodes over southern Ontario. Precipitation bands linked to both warm and cold fronts were mainly responsible ...

Abstract: Rain?snow boundaries in two southern Ontario storms are examined. Radar and satellite information were used to illustrate the nature and extent of the associated precipitation and cloud regions. The deepest radar echoes ...

Abstract: The effects of particle fallspeeds on the downwind spread of initially vertical columns or curtains are examined in environments with wind shear. Sets of equations describing the column width as a function of time and ...

Abstract: The microphysical consequences of seeding stratiform clouds near the Sierra Nevada Mountains are examined. Airborne seeding was conducted with droppable AgI flares released every 250 m and with dry ice pellets released at ...

Abstract: Several types of precipitation, such as freezing rain, ice pellets, and wet snow, are commonly observed during winter storms. The objective of this study is to better understand the formation of these winter precipitation ...

Abstract: A frontal system passed over the Storm Transfer and Response Experiment project area on 17 November 1980. As revealed by ship-born rawinsonde, surface, and radar information, this northeast Pacific storm exhibited three ...

Abstract: On 1?2 February 1992 a major storm produced a prolonged period (6 h) of ice pellets over St. John's, Newfoundland. At least two key features contributed to the prolonged duration. First, a subsaturated region within an ...
