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.
Hurricanes help to maintain the global heat balance by moving warm, moist tropical air to the mid-latitudes and polar regions [5] and also by influencing ocean heat transport. [6] Were it not for the movement of heat poleward (through other means as well as hurricanes), the tropical regions would be unbearably hot.
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 ...
An extratropical cyclone is a storm that derives energy from horizontal temperature differences, which are typical in higher latitudes. A tropical cyclone can become extratropical as it moves toward higher latitudes if its energy source changes from heat released by condensation to differences in temperature between air masses.
Typhoon Parma (left) and Melor (right) interacting with each other in the Philippine Sea on October 6, 2009.. The Fujiwhara effect, sometimes referred to as the Fujiwara effect, Fujiw(h)ara interaction or binary interaction, is a phenomenon that occurs when two nearby cyclonic vortices move around each other and close the distance between the circulations of their corresponding low-pressure areas.
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.
The cyclone slammed the area with robust winds throughout much of the day and caused signifi. Portions of southern Brazil and Uruguay were buffeted by strong winds, heavy rain and rough seas ...
The now mid-latitude cyclone then moved eastwards, bringing blizzard conditions to the Rocky Mountains and Great Plains on January 7. Six states recorded whiteout conditions during this time. Six states recorded whiteout conditions during this time.
