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.
As such, the idea of numerical weather prediction is to sample the state of the fluid at a given time and use the equations of fluid dynamics and thermodynamics to estimate the state of the fluid at some time in the future. The process of entering observation data into the model to generate initial conditions is called initialization.
A tropical cyclone forecast model is a computer program that uses meteorological data to forecast aspects of the future state of tropical cyclones. There are three types of models: statistical, dynamical, or combined statistical-dynamic. [1] Dynamical models utilize powerful supercomputers with sophisticated mathematical modeling software and ...
Global Forecast System. 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).
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 Weather Research and Forecasting ( WRF) Model [1] ( / ˈwɔːrf /) is a numerical weather prediction (NWP) system designed to serve both atmospheric research and operational forecasting needs. NWP refers to the simulation and prediction of the atmosphere with a computer model, and WRF is a set of software for this.
The Unified Model is a numerical weather prediction and climate modeling software suite originally developed by the United Kingdom Met Office, [1] [2] and now both used and further developed by many weather-forecasting agencies around the world. [3] The Unified Model gets its name because a single model is used across a range of both timescales ...
In 2023, Dan Collins, meteorologist at the Climate Prediction Center, told the Cape Cod Times that powerful computer models and significant staff hours formulate the outlooks, which are used by ...
