The "Bergen School of Meteorology" is a school of thought which is the basis for much of modern weather forecasting.Founded by the meteorologist Prof. Vilhelm Bjerknes and his younger colleagues in 19...
Rainband
A rainband is a cloud and precipitation structure associated with an area of rainfall which is significantly elongated. Rainbands can be stratiform or convective, and are generated by differences in ...

Subtropical Storm Andrea (2007)
Subtropical Storm Andrea was the first named storm and first subtropical cyclone of the 2007 Atlantic hurricane season. It developed out of a non-tropical low on May 9 about 150 miles (240 k...

Mesocyclone
A mesocyclone is a vortex of air within a convective storm.It is air that rises and rotates around a vertical axis, usually in the same direction as low pressure systems in a given hemisphere. They ar...

Mesoscale convective system
A mesoscale convective system (MCS) is a complex of thunderstorms that becomes organized on a scale larger than the individual thunderstorms but smaller than extratropical cyclones, and normally persi...
Atmospheric tide
Atmospheric tides are global-scale periodic oscillations of the atmosphere. In many ways they are analogous to ocean tides. Atmospheric tides can be excited by:
The largest-amplitude atmospheric t...

Tornadogenesis
Tornadogenesis is the process by which a tornado forms. There are many types of tornadoes, and each type of tornado can have several different methods of formation. Scientific study is ongoing, as som...

Yolanda (storm)
Yolanda was a weak, but devastating non-tropical cyclone which caused widespread flooding in eastern Europe.
Yolanda was first identified on 14 May over the southern Mediterranean Sea near Al...
Polar front
In meteorology, the polar front is the boundary between the polar cell and the Ferrel cell in each hemisphere. At this boundary a sharp gradient in temperature occurs between these two air masses, eac...
Weather map
A weather map displays various meteorological features across a particular area at a particular point in time and has various symbols which all have specific meanings. Such maps have been in use sinc...

Kona low
Kona storms (also called Kona lows) are a type of seasonal cyclone in the Hawaiian Islands, usually formed in the winter from winds coming from the westerly "kona" (normally leeward) direction. They...

1982 Florida subtropical storm
The 1982 Florida subtropical storm, officially known as Subtropical Storm One, was the only subtropical cyclone of the inactive 1982 Atlantic hurricane season. The storm originated from two different ...

Mesoscale convective vortex
A mesoscale convective vortex (MCV) is a low-pressure center within an mesoscale convective system (MCS) that pulls winds into a circling pattern, or vortex. With a core only 30 to 60 miles (97 ...

Stationary front
A stationary front is a collection of air masses, neither of which is strong enough to replace the other. On a weather map, this is shown by an inter-playing series of blue spikes pointing one directi...

Storm track
Storm tracks are the relatively narrow zones in seas and oceans where storms travel driven by the prevailing winds. The Atlantic and Pacific have storm tracks along which most Atlantic or Pacific ext...
Occluded front
An occluded front is formed during the process of cyclogenesis when a cold front overtakes a warm front. When this occurs, the warm air is separated (occluded) from the cyclone center at the Earth's s...
