Learn how mathematical models of the atmosphere and oceans are used to predict the weather and climate based on current conditions and observations. Explore the history, methods, challenges and applications of numerical weather prediction.
GEM is a Canadian weather forecasting and data assimilation system that runs out to 16 days. It has different variants for global, regional and mesoscale applications, and uses a hydrostatic primitive equation with a terrain following pressure coordinate.
WRF stands for Weather Research and Forecasting Model, a software for simulating and predicting the atmosphere with a computer model. WRF has two dynamical cores, a data assimilation system, and a flexible architecture for various meteorological applications.
It comprises a spectral atmospheric model with a terrain-following vertical coordinate system coupled to a 4D-Var data assimilation system.In 1997 the IFS became the first operational forecasting system to use 4D-Var. [2] Both ECMWF and Météo-France use the IFS to make operational weather forecasts, but using a different configuration and resolution (the Météo-France configuration is ...
In weather forecasting, model output statistics (MOS) is a multiple linear regression technique in which predictands, often near-surface quantities (such as two-meter-above-ground-level air temperature, horizontal visibility, and wind direction, speed and gusts), are related statistically to one or more predictors.
The Global Forecast System (GFS) is a U.S. numerical weather prediction system that produces forecasts for up to 16 days in advance. It uses a FV3 model with 13 km resolution and runs four times a day, and is the basis for many private and foreign weather forecasts.
Weather forecasting is the science and technology of predicting the conditions of the atmosphere for a given location and time. Learn about the ancient and modern methods, the use of computer models, the sources of data, and the applications and challenges of weather forecasting.
Learn about the CF conventions for describing Earth sciences data, which enable data sharing and processing. Find out the history, applications, data types, formats, and design principles of CF conventions.
