Medium Range Weather Forecast (10 Days Forecast)

Model Products Description

The ICOsahedral Nonhydrostatic model (ICON) is the new global numerical weather prediction model by DWD. It became operational on 2015-01-20, replacing the previous operational global model, GME. The ICON modelling system as a whole is developed jointly by DWD and the Max-Planck Institute for Meteorology, Hamburg, Germany (MPI-M).The model is run at spatial resolution of 13Km for a period of 72 hours.


The Global Forecast System (GFS) is a global numerical weather prediction model run by NOAA. It produces a short-medium range weather forecast for 3-7 days. GFS operates daily at 00UTC on a horizontal resolution of 25km.


The US Air Force’s 557th Weather Wing creates the Global Ensemble Prediction Suite (GEPS) twice per day by ingesting 63 global forecast model runs produced by three operational numerical modeling centers and creating tailored statistical ensemble forecasts. Products include probabilities for precipitation and snowfall, and means/standard deviations of temperature, wind, pressure, height, and relative humidity. 7 Days forecast at one-degree gridded output is produced at the intervals of 6 hours.


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). The numerical model outputs are available at a horizontal resolution of 1o for 7 days.


ECMWF introuduced a new model cycle of the Integrated Forecasting System (IFS) into operations in 2016. Cycle 41r2 represents a significant step forward in accuracy and resolution and, at a grid spacing of 9 km, it is currently the highest-resolution global forcasting system in the world. In combination with several other scientific and technical changes, this has led to a significant increase in forecast accuracy and computational efficiency
