Topics related to "anticyclone"

anticyclone
anticyclone region of high atmospheric pressure; anticyclones are commonly referred to as "highs." The pressure gradient, or change between the core of the anticyclone and its surroundings, combined with the Coriolis effect , causes air to circulate about the core in a clockwise direction in t...

isobar
isobar or isobaric line , line drawn on a weather map through points of equal atmospheric pressure. Isobars are used to define cyclones (low-pressure regions) and anticyclones (high-pressure regions). Weather maps are designed to depict the horizontal pressure distribution across an area of land...

Sir Francis Galton
Sir Francis Galton , 1822-1911, English scientist, founder of eugenics; cousin of Charles Darwin . He turned from exploration and meteorology (where he introduced the theory of the anticyclone ) to the study of heredity and eugenics (a term that he coined). Galton devised the correlation coeffic... Read more
horse latitudes
horse latitudes two belts of latitude where winds are light and the weather is hot and dry. They are located mostly over the oceans, at about 30° lat. in each hemisphere, and have a north-south range of about 5° as they follow the seasonal migration of the sun. The horse latitudes are assoc... Read more
cyclone
cyclone atmospheric pressure distribution in which there is a low central pressure relative to the surrounding pressure. The resulting pressure gradient, combined with the Coriolis effect , causes air to circulate about the core of lowest pressure in a counterclockwise direction in the Northern He... Read more
weather
weather state of the atmosphere at a given time and place with regard to temperature, air pressure (see barometer ), wind, humidity, cloudiness, and precipitation. The term weather is restricted to conditions over short periods of time; conditions over long periods, generally at least 30-50 year... Read more
