An extratropical cyclone is a synoptic scale low-pressure weather system that has neither tropical nor polar characteristics, being connected with fronts and horizontal gradients in temperature and dew point otherwise known as "baroclinic zones". [5] The descriptor "extratropical" refers to the fact that this type of cyclone generally occurs ...
Extratropical cyclones are classified mainly as baroclinic, because they form along zones of temperature and dewpoint gradient known as frontal zones. They can become barotropic late in their life cycle, when the distribution of heat around the cyclone becomes fairly uniform with its radius.
Comparison between extratropical and tropical cyclones on surface analysis. There are a number of structural characteristics common to all cyclones. A cyclone is a low-pressure area. [18] A cyclone's center (often known in a mature tropical cyclone as the eye), is the area of lowest atmospheric pressure in the region. [18]
For people on the ground, there is little difference between a subtropical and tropical storm. Both bring high winds and potential flooding.
Tropical and subtropical storms share similarities, but there are a few key differences.
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; [20] From an operational standpoint, a tropical cyclone is usually not considered to become a subtropical cyclone during its extratropical transition. [26]
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.
A typhoon is a type of tropical cyclone that occurs in the Northwest Pacific Ocean, specifically between 100°E and 180°E longitude. It is characterized by a well-defined circular structure with ...
