The Global Environmental Multiscale Model ( GEM ), often known as the CMC model in North America, is an integrated forecasting and data assimilation system developed in the Recherche en Prévision Numérique (RPN), Meteorological Research Branch (MRB), and the Canadian Meteorological Centre (CMC). Along with the NWS 's Global Forecast System ...
The Canadian Meteorological Centre ( CMC; French: Centre météorologique canadien ), located in Dorval, Quebec, is the branch of Environment Canada 's Meteorological Service of Canada that is tasked with providing forecast guidance to national and regional prediction centres, and is responsible for running the Global Environmental Multiscale ...
The Canadian Centre for Climate Modelling and Analysis ( CCCma) is part of the Climate Research Division of Environment Canada and is located at the University of Victoria, Victoria, British Columbia. Its purpose is to develop and apply climate models to improve understanding of climate change and make quantitative projections of future climate ...
Integrated Forecast System. The Integrated Forecasting System ( IFS) is a global numerical weather prediction system jointly developed and maintained by the European Centre for Medium-Range Weather Forecasts (ECMWF) based in Reading, England, and Météo-France based in Toulouse. [1] The version of the IFS run at ECMWF is often referred to as ...
The North American Ensemble Forecast System ( NAEFS) is a joint project involving the Meteorological Service of Canada (MSC) in Canada, the National Weather Service (NWS) in the United States, and the National Meteorological Service of Mexico (NMSM) in Mexico providing numerical weather prediction ensemble guidance for the 1- to 16-day forecast ...
FORECAST is a management-oriented, stand-level, forest-growth and ecosystem-dynamics model. The model was designed to accommodate a wide variety of silvicultural and harvesting systems and natural disturbance events (e.g., fire, wind, insect epidemics) in order to compare and contrast their effect on forest productivity, stand dynamics, and a series of biophysical indicators of non-timber values.
The use of model ensemble forecasts since the 1990s helps to define the forecast uncertainty and extend weather forecasting farther into the future than otherwise possible. Background [ edit ] Until the end of the 19th century, weather prediction was entirely subjective and based on empirical rules, with only limited understanding of the ...
The global models are run at varying times into the future. The Met Office's Unified Model is run six days into the future, the European Centre for Medium-Range Weather Forecasts model is run out to 10 days into the future, while the Global Forecast System model run by the Environmental Modeling Center is run 16 days into the future.
