The descriptor extratropical signifies that this type of cyclone generally occurs outside the tropics and in the middle latitudes of Earth between 30° and 60° latitude. They are termed mid-latitude cyclones if they form within those latitudes, or post-tropical cyclones if a tropical cyclone has intruded into the mid latitudes.
World map with the middle latitudes highlighted in red Extratropical cyclone formation areas. The middle latitudes, also called the mid-latitudes (sometimes spelled midlatitudes) or moderate latitudes, are spatial regions on either hemisphere of Earth, located between the Tropic of Cancer (latitude 23°26′09.8″) and the Arctic Circle (66°33′50.2″) in the northern hemisphere and ...
A dangerous weather phenomenon called a bomb cyclone that occurs in mid-latitudes - between Earth's tropics and the polar regions - can bring strong and damaging winds, torrential rains, heavy ...
Extratropical cyclones, sometimes called mid-latitude cyclones, are a group of cyclones that occur in the middle latitudes of the Earth, and which have neither tropical nor polar characteristics. They are connected with fronts and feature changes in temperature and dew point horizontally, otherwise known as "baroclinic zones".
A bomb cyclone is defined as a mid-latitude cyclone over the Pacific Ocean that drops 24 millibars — a measure of atmospheric pressure — over 24 hours. This particular bomb could drop 50-60 ...
Cyclones have also been seen on extraterrestrial planets, such as Mars, Jupiter, and Neptune. [7] [8] Cyclogenesis is the process of cyclone formation and intensification. [9] Extratropical cyclones begin as waves in large regions of enhanced mid-latitude temperature contrasts called baroclinic zones.
A “dynamic mid-latitude cyclone” is spreading scattered showers and thunderstorms onto the East Coast on Thursday, according to the National Weather Service (NWS). Moderate to heavy snow is ...
The descriptor "extratropical" refers to the fact that this type of cyclone generally occurs outside of the tropics, in the middle latitudes of the planet. These systems may also be described as "mid-latitude cyclones" due to their area of formation, or "post-tropical cyclones" where extratropical transition has occurred, [ 5 ] [ 6 ] but are ...
