Map of the average temperature over 30 years. Data sets formed from the long-term average of historical weather parameters are sometimes called a "climatology". Various subtopics of climatology study different aspects of climate. There are different categorizations of the sub-topics of climatology.
Meteorology is a branch of the atmospheric sciences (which include atmospheric chemistry and physics) with a major focus on weather forecasting.The study of meteorology dates back millennia, though significant progress in meteorology did not begin until the 18th century.
The interdisciplinary, scientific study of the Earth's atmosphere with the primary focus being to understand, explain, and forecast weather events. Meteorology , is applied to and employed by a wide variety of diverse fields, including the military, energy production, transport, agriculture, and construction.
For the first time, precipitation and the clouds from which precipitation falls are called meteors, which originate from the Greek word meteoros, meaning 'high in the sky'. From that word comes the modern term meteorology, the study of clouds and weather.
Temperature is one of the principal quantities in the study of thermodynamics. Formerly, the magnitude of the kelvin was defined in thermodynamic terms, but nowadays, as mentioned above, it is defined in terms of kinetic theory. The thermodynamic temperature is said to be absolute for two reasons. One is that its formal character is independent ...
Finally, the Bergeron and Spatial Synoptic Classification systems focus on the origin of air masses that define the climate of a region. Paleoclimatology is the study of ancient climates. Paleoclimatologists seek to explain climate variations for all parts of the Earth during any given geologic period, beginning with the time of the Earth's ...
America Online CEO Stephen M. Case, left, and Time Warner CEO Gerald M. Levin listen to senators' opening statements during a hearing before the Senate Judiciary Committee on the merger of the two ...
It studies the periodicity of weather events over years to millennia, as well as changes in long-term average weather patterns, in relation to atmospheric conditions. Climatologists , those who practice climatology, study both the nature of climates – local, regional or global – and the natural or human-induced factors that cause climates ...
