A Medicane is a subtropical or tropical cyclonic storm system similar to a hurricane that occurs over the Mediterranean Sea. Medicanes do not usually reach hurricane strength, but may produce substantial damage because of their location near highly populated areas around the Mediterranean.[1] Although the Mediterranean is not an officially designated tropical cyclone basin, cyclones having properties of a tropical cyclone occasionally form in the mid-latitudes and on rare occasions over the Black Sea.[2][3][4] 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[clarification needed]
About once or twice per year,[5][6] usually during fall when the Mediterranean is still warm, a depression takes on the characteristics of a subtropical storm with clouds wrapped around an eye, intense thunderstorm activity, strong surface winds, and warm temperature in the center clouds. In a satellite image such a system can resemble a tropical storm, but without the dimensions or power. One example is a Medicane that threatened France from November 1, 2011 to November 9, 2011 and produced up to 800 mm of rain.[7] Many other storms have been classified as Medicanes.[8][unreliable source?]
Most Medicanes form in the western Mediterranean region, although some form in the Ionian region.[9] In fall there is a steady increase in Medicane formation in the western Mediterranean region and a decrease in January; in the Ionian region it is the reverse - Medicanes are much less frequent in fall than in January or February.[10]
Evolution and life cycle
Medicanes usually have a life cycle between 12 hours and 5 days and travel between ~700 and ~3,000 km.[11] Although similar to tropical cyclones in the Caribbean or the Atlantic, their evolution is different. Unlike hurricanes, which often evolve from a tropical wave, Medicanes often develop from a cold upper-level low.[12] In the first phase there is a baroclinic development. The second phase is much more like a convective tropical air-sea interaction[13] with sea temperatures above 26°C (78.8°F).
