The model is common development of consortium of 15 national meteorological services. This is a spectral model for regional forecasting of meteorological fields. Initial and boundary conditions are provided from the global model ARPEGE, which is a result of the common development between ECMWF and Meteo-France. The two models are close related. CMDR-COE 8 31May - 2 June 2016 ALADIN model. Region & Orography CMDR-COE 9 31May - 2 June 2016 Wave models output Products from the numerical wave models: • Significant wave height; • Mean direction of wave propagation; • Mean period; • Swell wave height; • Mean Swell direction; • Mean Swell period • Other parameters if needed by the end user CMDR-COE 10 May 31- 2 June 2016 Wave forecast (WW3) CMDR-COE 11 May 31- 2 June 2016 SWAN – high resolution coastal zone wave model CMDR-COE 12 May 31- 2 June 2016 Operational Wave forecast • The wave models (WW3 and SWAN) run in forecast mode, twice daily, based on 06:00 UTC and 18:00 UTC. • Wave products are available via INTERNET to the Regional meteorological center in Varna and Executive Agency MARITIME ADMINISTRATION-Maritime Rescue Co-ordination Centre - Varna; • The NIMH-BAS marine forecasting system issues “warnings of danger” in case of storm situations in the Black Sea; • The wave models results are archived and can be used for the statistical investigations of the sea state parameters in the Black Sea CMDR-COE 13 May 31- 2 June 2016 NIMH – METEOALARM WARNINGS Meteoalarm, a web-based service to warn people in Europe of severe weather Meteoalarm is developed by EUMETNET, the network of public European weather services who are members of the World Meteorological Organization (WMO). NIMH provides with atmospheric and marine operational numerical forecasts the coastal hazard Early Warning System and meteorological vigilance map EUROPEAN METEOALARM CMDR-COE 14 31May - 2 June 2016 NIMH – METEOALARM WARNINGS Meteoalarm, a web-based service to warn people in Europe of severe weather Meteoalarm is developed by EUMETNET, the network of public European weather services who are members of the World Meteorological Organization (WMO). NIMH provides with atmospheric and marine operational numerical forecasts the coastal hazard Early Warning System and meteorological vigilance map EUROPEAN METEOALARM CMDR-COE 15 31May - 2 June 2016 NIMH – METEOALARM WARNINGS Meteoalarm, a web-based service to warn people in Europe of severe weather . CMDR-COE 16 31May - 2 June 2016 NIMH – Floating pollutants drift forecast • Tanker transportation is the source of potential risks of the oil pollution in the Black Sea; The operational oil spill drift forecasting model of Meteo-France (MOTHY) was adopted for the Black Sea; CMDR-COE 17 May 31- 2 June 2016 Simulation of the oil slick CMDR-COE 18 31May 31- 2 June 2016 Simulation of the oil slick CMDR-COE 19 May 31- 2 June 2016 Oil spill simmulation CMDR-COE 20 May 31- 2 June 2016 Computer resources The numerical models have been implemented on a PC with two Intel processors, operating under LINUX operational system. Graphics software The Grid Analysis and Display System (GrADS) The Generic Mapping Tools (GMT) CMDR-COE 21 May 31- 2 June 2016 Conclusions The marine system is designed to: • Describe and forecast the Black Sea surface state; • Mitigate damage from natural hazards and pollution; • Protect life and property on coasts and at sea; • Enable scientific research; The system is a platform for regional cooperation and operational activities. The system is the component of the current National hydro- meteorological information system and a major component of the future Multi-Hazard Early Warning System.
