Klaus Fraedrich (* 1945 ) is a German meteorologist.

Life

Fraedrich studied at the University of Cologne , the University of Bonn and in Berlin. In 1970 he received his doctorate and was then a post-doctoral student at Colorado State University (Department of Atmospheric Sciences). In 1973 he received his habilitation and from 1975 was an adjunct professor at the University of Bonn and from 1975 to 1992 professor for meteorology at the Free University of Berlin . In 1979 he was visiting professor at the University of Wisconsin – Madison , in 1982/83 at the Australian Numerical Meteorology Research Center in Melbourne as Distinguished Oversea Scientist and in 1985 at the Joint Institute for the Study of the Atmosphere and Ocean at the University of Washington . From 1986 to 1988 he was a senior scientist at the Bureau of Meteorology Research Center in Melbourne. Since 1994 he has been visiting professor at the University of New South Wales in Sydney. He is a professor at the Meteorological Institute of the University of Hamburg , where he heads the Theoretical Meteorology working group .

In the 1970s, he dealt with regional climate problems (such as the local circulation over Lake Victoria) and the parameterization of cloud formation (for example cumulus clouds and cooling tower clouds). In the 1980s and 1990s he applied concepts of non-linear systems analysis to weather data and weather forecast (such as Markov chains, 1 / f noise, maximum entropy production). He dealt in particular with weather phenomena in China and Australia. In the 2000s he also developed simplified, freely accessible climate computer models such as SAM (Shallow Atmosphere Model), PUMA (Portable University Model of the Atmosphere) and PlaSim (Planet Simulator).

In 1994 he received the Max Planck Research Prize , in 2010 the Alfred Wegener Medal and the Lewis Fry Richardson Medal and in 2003 the Gay Lussac Humboldt Prize . He is a member of the Academy of Sciences in Hamburg and a "Fellow" of the Max Planck Society at the Max Planck Institute for Meteorology. From 1994 to 1996 he was President of the Nonlinear Dynamics Department of the European Geophysical Society. Since 1996 he has been a member of the Advisory Board on Global Change in the Federal Republic of Germany. Since 1993 he has been on the Scientific Advisory Board of the German Weather Service. From 1994 to 1996 he was Vice President of the Nonlinear Dynamics Working Group of the European Geophysical Society.
