Basic data about the project

WRF METEOPG is a weather forecasting system, operating and developed since 2018 at the TASK IT Center at the Gdańsk University of Technology, which uses the WRF 4.1 model. The forecasts from the WRF METEOPG are available to the IMWM-PIB under the signed cooperation agreement between the Gdańsk University of Technology and the Institute of Meteorology and Water Management from 2019.

The system uses high-resolution geographic data (including topography, subsoil roughness, land use) and optimized physics parametrisation for Central Europe. The operational model uses three immersed grids with resolutions of 12.5, 2.5 and 0.5 km, respectively. The first grid covers the European continent, the second grid covers Poland, and the third grid covers the Pomeranian Voivodeship. The system can also activate other grids with a resolution of 0.5 km for selected areas of Poland, e.g. the Tatra Mountains and Podhale. For weather forecasting, data from the global GFS (Global Forecast System) model with a resolution of 0.25 °, which includes coupled models of the atmosphere, soil and ocean, are assimilated. Alternatively, the system can assimilate data from the European ICON-EU model with a resolution of 6.6 km. The WRF model during the day is activated for the four main synoptic dates 00, 06, 12 and 18 with a forecast time of 60 hours.

The weather forecasting computing system works on the supercomputer TRYTON, using 24 computing nodes. This model was also used in the weather service of the IMWM-PIB meteo.imgw.pl.
