In meteorology, an air mass is a volume of air defined by its temperature and water vapor content

The Westerlies, anti-trades, or Prevailing Westerlies, are prevailing winds from the west toward the east in the middle latitudes between 30 and 60 degrees latitude

In meteorology, the polar front is the boundary between the polar cell and the Ferrel cell in each hemisphere

air mass
In meteorology, an air mass is a volume of air defined by its temperature and water vapor content
cold front
A cold front is defined as the leading edge of a cooler mass of air, replacing at ground level a warmer mass of air, which lies within a fairly sharp surface trough of low pressure
occluded front
An occluded front is formed during the process of cyclogenesis when a cold front overtakes a warm front
stationary front
A stationary front is a pair of air masses, neither of which is strong enough to replace the other
A tornado is a violently rotating column of air that rotates while in contact with both the surface of the Earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud
Cyclone
In meteorology, a cyclone is a large scale air mass that rotates around a strong center of low atmospheric pressure
mesocyclone
A mesocyclone is a vortex of air within a convective storm
floods
A flood is an overflow of water that submerges land which is usually dry
weather forecast
Weather forecasting is the application of science and technology to predict the state of the atmosphere for a given location
