A Medicane is a subtropical or tropical cyclonic storm system similar to a hurricane that occurs in the Mediterranean Sea. Usually these cyclonic storms do not reach hurricane strength, but are still generating a lot of damage due to highly populated areas in the Mediterranean. Even though the Mediterranean is not an official tropical cyclone basin, and thus not under the authority of any Regional Specialized Meteorological Center like the National Hurricane Center, cyclones occasionally form in the mid-latitudes and on very rare occasions in the Black Sea, having properties of a tropical cyclone. A medicane is small, has an axisymmetric cloud structure, generates strong winds, heavy rains and thunderstorms. This phenomenon has often been named Medicane or Tropical-like Mediterranean Storm (T.M.S.).

Origin and local sub futures

At least once or twice every year, usually during fall when the Mediterranean Sea is still warm, a depression takes on the characteristics of a subtropical storm with clouds wrapped around an eye, intense thunderstorm activity, strong winds at surface winds and warm temperature in the center clouds. In a satellite image such a system can look very similar to a tropical storm, but without having the dimensions or the power. An example for such a cyclonic storm is a Medicane that threatened France from November 1 2011 to November 9 2011 and produced up to 800 mm of rain.There are many more storms that were classified as Medicanes.

Most Medicanes form in the western Mediterranean region, and some form in the Ionian region, whereas it is to note that there is a difference between the two regions: In fall there is a steady increase in Medicane formation in the western Mediterranean region whereas it decreases in January, in the Ionian region it is vise versa and Medicanes are much less frequent in fall than in January or February.

Evolution and life cycle

Medicanes usually have a life cycle between 12 hours and 5 days and travel between ~700 and ~3,000 km. These cyclonic storms are similar to tropical cyclones in the caribbean or the atlantic, there are some differences concerning evolution of theses storms. Unlike hurricanes, which often evolve from a tropical wave, Medicanes often have developed from a cold upper-level low. In the first phase there is a baroclinic development, the second phase, however is much more like a convective tropical air-sea interaction with sea temperatures above 26°C (78.8°F)
