Halleys Comet Halleys comet can be seen every 75-76 years, which last appeared in the inner Solar System in 1986, and will next appear in mid 2061. Halley published a map of the trade winds in 1686, after a voyage to the southern hemisphere. Francis Galton Sir Francis Galton F.R.S. (February 16, 1822 January 17, 1911), half-cousin of Charles Darwin, was an English Victorian polymath, anthropologist, eugenicist, tropical explorer, geographer, inventor, meteorologist, proto- geneticist, psychometrician, and statistician. Francis Galton invented the term anticyclone As the initiator of scientific meteorology: he invented the weather map, proposed a theory of anticyclones and was the first to establish a complete record of short-term climatic phenomena on a European scale. The Kppen world climate map It is based on the concept that native vegetation is the best expression of climate, thus climate zone boundaries have been selected with vegetation distribution in mind. It combines average annual and monthly temperatures and precipitation, and the seasonality of precipitation. Wladimir Peter Kppen (September 25, 1846 in Saint Petersburg, Russia June 22, 1940 in Graz, Austria) was a German meteorologist, climatologist and botanist. He elaborated the Kppen climate classification system, which is still commonly used today to group climates into similar types (albeit with modifications). Helmut Landsberg Helmut Erich Landsberg was born in Frankfurt, Germany, in February 1906. Died in 1985. While in Germany, he went to college at the University of Frankfurt and received his Ph.D. in 1930 with his dissertation focusing on seismographic records. During his early career, he focused his research on earthquakes. He became a director of the Taunus Observatory of Geophysics and Meteorology at the University of Frankfurt, Germany. Physical Climatology (1941). Urban Climate (1981). Weather and Health: An Introduction to Biometeorology (1969). Weather Climate and Human Settlements (1976). He began to raise the status of climatology from one of geographic classification to a well-developed applied physical science. His book, Physical Climatology, stressed for the first time in English, the use of statistical analysis in climatology. He produced strategic summaries of the climatological conditions for much of Europe Hubert Lamb Hubert Horace Lamb (1913 - 1997) was an English climatologist who founded the Climatic Research Unit at the University of East Anglia. Books: Climate, History and the Modern World Climate Present Past and Future Most of his scientific life Lamb spent at the Meteorological Office, UK, where he started as a Technical Officer by special merit promotion. His responsibilities were in the fields of long range weather forecasting, world climatology and climate change. In this capacity he spent some years in Antarctica and in Malta and North Africa and became a Member of the WMO Working Group on Climate Fluctuations and the First Director of the Climate Research unit, University of East Anglia, UK. Milutin Milankovi Milutin Milankovi (also known as Milankovitch) (May 28, 1879, Dalj near Osijek, (Austria- Hungary) December 12, 1958, Belgrade) was a Serbian geophysicist, best known for his theory of ice ages, relating variations of the Earths orbit and long-term climate change, now known as Milankovitch cycles.
