Current weather conditions over Europe and Eastern Mediterranean are available in the form of thematic maps of the mean sea level pressure, temperature, wind and precipitation.The maps are produced by the assimilation of various types of surface and upper air observations (METAR, SYNOP, RAOBS) and satellite retrievals for the precipitation estimation. The nowcasts have hourly updated rate.
Seasonal prediction’s significance lies on its ability to provide early warnings about oncoming and extreme weather episodes.The provided charts depict a qualitative representation of the atmospheric conditions that are likely to prevail over Europe for the winter 2017 and summer 2017 based on simulations with initial conditions on August 2016. The charts are based on the processed outputs of the ensemble members, a few of them are freely available here.
Data is updated every 30 minutes and the detections of the last 2 hours (120 minutes) are shown on the map with different color. The time unit of the map is referred in UTC. Winter time in Greece is UTC+2 and summer time is UTC+3.
The Atmosphere&Climate Dynamics Group (ACDG) operates a network of surface meteorological stations. The network is still under development and it includes 3 stations in Attiki and Peloponnesus, so far. The network is planning to expand by the end of the year 2014. The stations are installed in cooperation with the Institute of Environmental Research and Sustainable Development of the National Observatory of Athens (http://meteo.gr) and the Institute of Marine Biological Resources and Inland Waters of the Hellenic Centre for Marine Research. The characteristics of the stations are following.
