Abstract: This paper describes validation tests of the Canadian Updateable Model Output Statistics (UMOS) system against the perfect prognosis forecast system and forecasts of weather elements from the operational numerical weather ...

Abstract: The use of model output statistics (MOS) in operational weather element prediction has been hindered since the mid-1980s by frequent changes in the operational numerical weather prediction models that supply the predictors ...

Abstract: ince November 2014, the Meteorological Services of Canada (MSC) has been running a real-time numerical weather prediction system that provides deterministic forecasts on a regional domain with a 2.5-km horizontal grid ...
