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.
Extratropical cyclone – a low-pressure weather system occurring in the middle latitudes of the Earth having neither tropical nor polar characteristics; Weather front – a boundary separating two masses of air of different densities; the principal cause of meteorological phenomena
A weather front is a boundary separating air masses for which several characteristics differ, such as air density, wind, temperature, and humidity.Disturbed and unstable weather due to these differences often arises along the boundary.
A weather front is a boundary separating two masses of air of different densities, and is the principal cause of meteorological phenomena. In surface weather analyses , fronts are depicted using various colored lines and symbols, depending on the type of front.
The first daily weather forecasts were published in The Times in 1861. [16] In the following year a system was introduced of hoisting storm warning cones at the principal ports when a gale was expected. [18] The "Weather Book" which FitzRoy published in 1863 was far in advance of the scientific opinion of the time.
Also actiniform. Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...
A weather station is a facility with instruments and equipment to make observations of atmospheric conditions in order to provide information to make weather forecasts and to study the weather and climate. The measurements taken include temperature, barometric pressure, humidity, wind speed, wind direction, and precipitation amounts.
Atmospheric thermodynamics is the study of heat-to-work transformations (and their reverse) that take place in the Earth's atmosphere and manifest as weather or climate. . Atmospheric thermodynamics use the laws of classical thermodynamics, to describe and explain such phenomena as the properties of moist air, the formation of clouds, atmospheric convection, boundary layer meteorology, and ...
