Poland Meteorological Service (IMGW) is the national meteorological and hydrological institute of Poland, responsible for weather observation, forecasting, hydrology, and climatology. Established in the aftermath of World War I, the institute serves as the primary provider of meteorological data for civil protection, aviation, agriculture, and marine activities. IMGW operates a network of observatories, research units, and forecasting centers that collaborate with domestic and international organizations.

History

IMGW traces roots to institutions formed during the Second Polish Republic after World War I, reflecting influences from Józef Piłsudski-era reconstruction and interwar science policy. During World War II, operations were affected by the invasions of Nazi Germany and the Soviet Union, with staff and instruments dispersed as in other Polish scientific institutions such as the Polish Academy of Sciences and the Jagiellonian University. In the Communist era, IMGW was reorganized alongside ministries including the Ministry of Transport and Maritime Economy and later aligned with restructuring in the 1990s following the fall of Communist Poland and political reforms headed by leaders like Lech Wałęsa. Post-1990 reforms integrated IMGW with European frameworks such as the European Centre for Medium-Range Weather Forecasts and collaborations with agencies like MeteoFrance and Deutscher Wetterdienst.

Organization and Structure

The institute is headquartered in Warsaw and structured into regional branches, specialized laboratories, and operational centers similar to models used by Met Office and National Weather Service (United States). Governance links to the Ministry of Climate and Environment and oversight involves advisory boards drawing experts from the University of Warsaw, AGH University of Science and Technology, and the Institute of Geophysics Polish Academy of Sciences. Internal departments include synoptic forecasting units, hydrology divisions, climatology research teams, and IT and data management sections modeled on international counterparts such as Copernicus Programme components and the World Meteorological Organization frameworks.

Responsibilities and Services

IMGW provides national weather forecasts, hydrological bulletins, climate monitoring, and warnings for hazards including severe storms, floods, and droughts, supporting sectors like aviation via Warsaw Chopin Airport services and maritime navigation for ports such as Gdańsk and Szczecin. It issues official warnings used by agencies including the Chief Commander of the State Fire Service and the Main Inspectorate of Road Transport. IMGW supplies data to research institutes like the Institute of Meteorology and Water Management (historical predecessors), universities such as Adam Mickiewicz University in Poznań, and international bodies including the European Flood Awareness System.

Observational Network and Facilities

The observational network comprises synoptic stations, automatic weather stations, hydrological gauging stations on rivers like the Vistula and Oder, upper-air sounding sites, and marine buoys in the Baltic Sea. Key facilities include long-term climatological stations in cities such as Kraków, Wrocław, and Łódź, radar sites co-located with aviation installations at airports like Kraków John Paul II International Airport, and research laboratories collaborating with centers such as the Polish Academy of Sciences. Historical observatories influenced by figures associated with Nicolaus Copernicus-linked institutions remain part of the national heritage of meteorological observation.

Forecasting and Research

IMGW runs numerical weather prediction services, ensemble forecasting, and climate impact studies, using models interoperable with outputs from ECMWF, Met Office Unified Model, and regional models employed by CORDEX. Research topics cover extreme weather attribution in partnership with university departments like University of Warsaw Faculty of Physics, hydrological modelling for flood risk with agencies such as State Water Holding Polish Waters (Państwowe Gospodarstwo Wodne Wody Polskie), and climate change assessments contributing to national reports submitted to the United Nations Framework Convention on Climate Change. The institute publishes bulletins, scientific papers, and contributes data to repositories used by projects such as Horizon Europe consortia.

International Cooperation and Memberships

IMGW is a member of the World Meteorological Organization, participates in the European Centre for Medium-Range Weather Forecasts data exchange, and cooperates with EU initiatives including the Copernicus Programme and the European Flood Awareness System (EFAS). It engages bilaterally with neighboring services such as Deutscher Wetterdienst, Czech Hydrometeorological Institute, and Lithuanian Hydrometeorological Service, and contributes to NATO civil-military cooperation frameworks when needed. Participation in global networks includes upper-air data sharing via Global Telecommunication System channels and collaboration with International Civil Aviation Organization standards for aeronautical meteorological services.

Public Communication and Emergency Role

IMGW provides public forecasts, warning systems broadcast through national media outlets like Polsat and TVP, and digital platforms serving users including municipalities such as Warsaw City Hall and emergency services such as the State Fire Service. In flood events along the Vistula or Oder, IMGW supplies real-time river stage forecasts to Mayors of Polish municipalities and national crisis units coordinated with the Ministry of Interior and Administration. The institute’s warnings inform transport authorities managing roads like the A4 motorway and rail operators including Polish State Railways (PKP), and support agricultural advisories for regions such as Podlaskie Voivodeship. Emergency response integration follows protocols similar to those promoted by the European Civil Protection Mechanism.
