METEOROLOGY Demetrius Ivory WTAE I THE SCIENCE OF METEOROLOGY A. Definition: According to the American Meteorological Society, meteorology is the science of the atmosphere. It takes its name from the Greek word "meteoron"- something that happens in the sky. B. History and Timeline 350 BC - Aristotle writes Meteorology . The book is not about the science, as we know it today. Meteorology was more an earth science book that dealt with air and water. A very notable and impressive achievement in Meteorology was his description of the hydrologic cycle. In his own words: " Now the sun, moving as it does, sets up processes of change and becoming and decay, and by its agency the finest and sweetest water is everyday carried up and is dissolved into vapour and rises to the upper region where it is condensed again by the cold and so returns to the earth." 1494 - Christopher Columbus experiences a tropical cyclone. First written European account of a hurricane. 1606 - Galileo Galilei invents the thermometer. 1647 - Blaise Pascal determines that atmospheric pressure decreases with height. 1654 - Ferdinand de Medici finances the first weather observing network in Tuscany, Italy. 1686 - Edmund Halley identifies solar heating as the mechanism which drive atmospheric motions. 1686 - Edmund Halley shows a relationship between barometric pressure and atmospheric sea level. 1714 - Gabriel Fahrenheit creates the reliable temperature measuring scale. 1742 - Anders Celsius, a Swedish astronomer creator the Centigrade temperature scale. 1841- first known weather maps prepared. 1847 - Hermann von Helmholtz publishes a statement on The First Law of Thermodynamics. Also called the law of conservation of energy. 1849 - Smithsonian Institute establishes an observation network with 150 observers who send data via telegraph.

1860 - Robert FitzRoy creates first daily "weather forecast" in England. 1873 - First hurricane warning issued by the U.S. Army Signal Corp. 1902 - Stratosphere is discovered. 1919 - Cyclone Model is introduced. 1941 - Pulsed radar network is introduced during WWII. Operators notice echoes from rain and snow. 1954 - Numerical weather prediction done on a routine basis. 1959 - Vanguard 2, the first weather satellite is launched on Feb 17. 1969 - Saffir-Simpson Hurricane Scale created. 1970 - NOAA becomes the NWS 1975 - First Geostationary Operational Environmental Satellite (GOES) launched into orbit. 1988 - WSR-88D type weather radar implemented in the U.S. C. Technology Since 1959 meteorological satellites have provided an overview of the atmosphere's cloud patterns. Infrared sensors mounted on meteorological satellites now provide observations of the vertical temperatures of the atmosphere, and research efforts continue the development of computer forecasting models. There is a large use of computers for modeling. II
