Extratropical cyclones, sometimes called mid-latitude cyclones or wave cyclones, are low-pressure areas which, along with the anticyclones of high-pressure areas, drive the weather over much of the Earth.
Extratropical cyclone, a type of storm system formed in middle or high latitudes, in regions of large horizontal temperature variations called frontal zones. Extratropical cyclones present a contrast to the more violent cyclones or hurricanes of the tropics, which form in regions of relatively.
Extratropical cyclones (cyclones outside of the tropics) are covered here, and include transient mid-latitude cyclones and polar cyclones. Other names for extratropical cyclones are lows or low-pressure centers (see Table 13-1).
13 wrz 2024 · Of the two types of large-scale cyclones, extratropical cyclones are the most abundant and exert influence on the broadest scale; they affect the largest percentage of Earth’s surface.
Extratropical cyclones are among the largest disturbances of atmospheric circulation found on Earth. These giant low-pressure systems of the middle latitudes typically span the entire depth of the troposphere vertically, frequently involve lower stratospheric air, and extend 1000–3000 km in horizontal diameter.
An extra-tropical cyclone is a low-pressure system that primarily gets its energy from the temperature difference in the horizontal direction across the cyclone (known as temperature gradient in meteorology).
Extratropical cyclones are large-scale weather systems that form outside of the tropics, characterized by low-pressure centers and typically associated with fronts. These cyclones play a significant role in the weather patterns of mid-latitude regions, bringing changes in temperature, precipitation, and wind as they move through the atmosphere.
