RISBias Correction and Multiensemble in the NAEFS Context or How to Get a “Free Calibration” through a Multiensemble Approach
Publisher: American Meteorological Society
Abstract: Previous studies have shown that the raw combination (i.e., the combination of the direct output model without any postprocessing procedure) of the National Centers for Environmental Prediction (NCEP) and Meteorological ...
Toward Random Sampling of Model Error in the Canadian Ensemble Prediction System
Publisher: American Meteorological Society
Abstract: An updated global ensemble prediction system became operational at the Meteorological Service of Canada in July 2007. The new elements of the system include the use of 20 members instead of 16, a single dynamical core [the ...
Higher Resolution in an Operational Ensemble Kalman Filter
Publisher: American Meteorological Society
Abstract: ecently, the computing facilities available to the Meteorological Service of Canada were significantly upgraded. This provided an opportunity to improve the resolution of the global ensemble Kalman filter (EnKF) and the ...
GEPS-Based Monthly Prediction at the Canadian Meteorological Centre
Publisher: American Meteorological Society
Abstract: ynamical monthly prediction at the Canadian Meteorological Centre (CMC) was produced as part of the seasonal forecasting system over the past two decades. A new monthly forecasting system, which has been in operation since ...
Impact of Surface Parameter Uncertainties within the Canadian Regional Ensemble Prediction System
Publisher: American Meteorological Society
Abstract: he aim of this study is to assess the impact of uncertainties in surface parameter and initial conditions on numerical prediction with the Canadian Regional Ensemble Prediction System (REPS). As part of this study, the ...
