RISFour-Dimensional Variational Data Assimilation for the Canadian Regional Deterministic Prediction System
Publisher: American Meteorological Society
Abstract: s a second step in the development of the Canadian Regional Data Assimilation System following Fillion et al., this study extends the approach to the four-dimensional variational data assimilation (4D-Var) context. Emphasis ...
Implementation of Deterministic Weather Forecasting Systems Based on Ensemble–Variational Data Assimilation at Environment Canada. Part I: The Global System
Publisher: American Meteorological Society
Abstract: major set of changes was made to the Environment Canada global deterministic prediction system during the fall of 2014, including the replacement of four-dimensional variational data assimilation (4DVar) by four-dimensional ...
The Canadian Regional Data Assimilation and Forecasting System
Publisher: American Meteorological Society
Abstract: This paper describes the recent changes to the regional data assimilation and forecasting system at the Canadian Meteorological Center. A major aspect is the replacement of the currently operational global variable resolution ...
