Early emergency response by means of dispersion forecasting – emergency management of the Deutscher Wetterdienst in the context of national and international agreements
-
T. Steinkopff
Abstract
Based on results of the numerical weather forecast models; the DWD (Deutscher Wetterdienst, German Meteorological Service) is immediately able to calculate dispersion forecasts in the case of an emergency with an emission of radioactive inventory. This information is essential for the management of further countermeasures. There are legal agreements between the federal states of Germany and the Federal Government regulating the mutual aid. For the emergency preparedness system RODOS (Real Time Online Decision Support) the results of the numerical weather forecasts are provided and complemented by medium-range dispersion forecasts. In the framework of the German computer network IMIS (Integrated Measurement and Information System for the Surveillance of Radioactivity in the Environment) the results of trajectory calculations are presented graphically within 10 minutes, those from the LPDM (Lagrangian Particle Dispersion Model) forecasts within 30 minutes. In case of a nuclear emergency, global distribution of information via the WMO (World Meteorological Organization) communication system GTS is part of international agreements between IAEA (International Atomic Energy Agency) and WMO, thus giving the DWD a key role. The commitments of the DWD in managing nuclear emergencies in the framework of national and international agreements are presented, as well as internal emergency arrangements.
Kurzfassung
Basierend auf den Ergebnissen der numerischen Wettervorhersage wurden Verfahren entwickelt, durch die der Deutsche Wetterdienst bei Unfallereignissen mit Freisetzung von radioaktivem Inventar jederzeit in der Lage ist, meteorologische Daten und Ergebnisse von Ausbreitungsprognoserechnungen bereitzustellen. Diese Informationen sind für alle weiteren Planungen im Unfallmanagement von entscheidender Bedeutung. Im Rahmen der Katastrophenschutzgesetze der Bundesländer gibt es Vereinbarungen zur schnellen Hilfeleistung. Für das Entscheidungshilfesystem RODOS werden bei Bedarf sofort die dazu erforderlichen Ergebnisdaten aus der numerischen Wettervorhersage versandt sowie, falls notwendig, die großräumigen Ausbreitungsprognosen ergänzt. Im Rahmen von IMIS werden die Ergebnisse von Trajektorienrechnungen und LPDM-Ausbreitungsprognosen innerhalb von 10 Minuten bzw. 30 Minuten graphisch präsentiert. Auch im Rahmen der Vereinbarungen zwischen der IAEA und der WMO nimmt der Deutsche Wetterdienst eine wichtige Schlüsselposition zur weltweiten Verteilung von Informationen im Ereignisfall ein.
Die Verpflichtungen des DWD im Rahmen des nationalen und internationalen Warnmanagements bei kerntechnischen Ereignissen werden im einzelnen dargestellt und die internen Prozessabläufe im Fall einer Alarmierung beschrieben.
