Precipitation forecasts at the Canadian Meteorological Centre

Operational forecasts of precipitation amount are produced by a numerical scheme which uses the dew point depression as the moisture parameter. The onset of large scale precipitation occurs gradually when the dew point depression decreases below a threshold value. Small scale precipitation is divided into several meteorological components and each of these is parameterized separately. Improvements were recently obtained by reducing the horizontal grid spacing from 381 km to 190.5 km.DOI: 10.1111/j.2153-3490.1973.tb01593.x
