Born 1940 in Kiel, Germany 1962-1967 study for a degree in meteorology in Kiel, Germany 1973 PhD in Kiel 1967-1975 Scientist at the Institut für Meereskunde in Kiel, Germany 1976-1991 Senior scientist at the European Centre for Medium-range Weather Forecast (ECMWF) in Reading, England (head of diagnostic section). 1991-2000 Senior scientist at Max-Planck-Institut für Meteorologie in Hamburg, Germany 2000 retired 2000-now some contracts with Max-Planck-Institut für Meteorologie to continue working on different projects. Mostly working on the Caspian Sea level. Activities: Main interests are the hydrological cycle of the atmosphere, diagnostic studies of atmospheric processes using observational and model data. At ECMWF the main work consisted in investigating the quality of the operational medium range forecasts, including their daily initial (analysis) data, leading later to the involvement in the ECMWF reanalysis project. Special interest was focused on the quality of precipitation estimates (consultancy at the Global Precipitation Climate Project). At the Max-Planck-Institute for Meteorology the diagnostic work shifted towards climate research. Recent interests were the Caspian Sea level variability in the past and future. Occasional teaching in the master program on “Climate change, impact and sustainability” at Brunel University, London. Peer reviewed publications: 53 of which there are 12 about the Caspian Sea
