The Climate Forecast System or coupled forecast system (CFS) is a medium to long range numerical weather prediction and a climate model run by the National Centers for Environmental Prediction (NCEP) to bridge weather and climate timescales. [1] Version 2 became operational as CFSv2 in 2011. [2]
In New York City, for example, the stretch from Sunday to Thursday is likely to be the coldest start to December since 2019, when highs ranged from 36-42 degrees during the Dec. 1-5 timeframe. The ...
The output of forecast models based on atmospheric dynamics is unable to resolve some details of the weather near the Earth's surface. As such, a statistical relationship between the output of a numerical weather model and the ensuing conditions at the ground was developed in the 1970s and 1980s, known as model output statistics (MOS).
The global models are run at varying times into the future. The Met Office's Unified Model is run six days into the future, [55] the European Centre for Medium-Range Weather Forecasts model is run out to 10 days into the future, [56] while the Global Forecast System model run by the Environmental Modeling Center is run 16 days into the future. [57]
"High temperatures the next couple of days will be roughly 10 to as much as 30 degrees below normal," National Weather Service forecaster Mark Miller said in an online forecast. "The cold post ...
During the 2014 January polar vortex, more than 20 people across the country died from the cold as places like Georgia — which rarely see serious cold — dealt with lows under 10 degrees ...
The Model for Prediction Across Scales (MPAS) is an Earth system modeling software that integrates atmospheric, oceanographic, and cryospheric modeling across scales from regional to planetary. It includes climate and weather modeling and simulations that were used initially by researchers in 2013. [ 1 ]
An example of a forecast product from the GFS, in this case a 96-hour forecast of 850 mb geopotential height and temperature. The Global Forecast System (GFS) is a global numerical weather prediction system containing a global computer model and variational analysis run by the United States' National Weather Service (NWS).
