About the European Windstorm Centre Edit
The EWC was set up in September 2009 to issue advisory's on windstorms in the North Atlantic Ocean. To go to the main site click the link above to Google Sites.
EWC Area of Responsibility (AoR) Edit
The EWC Area of Responsibility (AoR) covers the North Atlantic Ocean and the majority of Continental Europe along with the North, Baltic, Celtic and Norwegian Seas. The Mediterranean Basin covers the Alboran, Balearic, Ionian, Liguarian, Mediterranean, Tyrrhenian, Adriatic, Aegean and Black seas, the EWC issues advisories on the Tropical like cyclones that form over the sea and make landfall over France, Italy and Greece. The EWC is not a Regional Specialized Meteorological Center. Below is the Basin boundaries on a map of Europe.
North Atlantic Windstorm Basin Edit
This region includes the North Atlantic Ocean and the majority of Continental Europe along with the North, Baltic, Celtic and Norwegian Seas. Windstorm formation here varies widely form season to season, ranging from nice to over forty per season. Most European windstorms form between 1st September and 30th March. On average 25 named storms (of European cyclone strength or higher) occur each season.
Atlantic, Arctic and Scandinavian Europe are directly affected by Windstorms tracking North East from the eastern seaboard of The United States and Canada. Because Windstorms do not weaken rapidly upon landfall, unlike their tropical counterparts, windstorms can maintain intensity over a long period after landfall, therefore central and eastern Europe can still see the effects of European windstorms.
In more unusual events, windstorms can sometimes make landfall over Spain and Portugal, Morocco and Western Sahara.
Many of the more intense European windstorms have a Newfoundland track, originating as subtropical low pressure systems and nor'easter. Where they pass under or near the jet stream the strengthen, deep north easterly winds carry the storms up past the British Isles, Norway and Iceland. Examples of such windstorms are Windstorm Tina (2012-2013 Season), Windstorm Ike (2013-2014 Season) and Windstorm Karl (2014-2015 Season).
European Windstorm Scale Edit
Before 2011 the European Windstorm Centre used the Beaufort Scale as the method to measure windstorm intensity. After the 2011-12 season the European Windstorm Scale was introduced. A systems intensity is worked out by using the storms highest recorded wind gust. It is split into the generic 5 categories of Category 1 to Category 5 and one more, European Cyclone, the cyclone classification is rarely used, naming starts as European Cyclone intensity when the maximum gusts recorded reaches 40 mph.
Mediterranean Sea and Black Sea Tropical Cyclone Basin Edit
This region covers the Alboran, Balearic, Ionian, Liguarian, Mediterranean, Tyrrhenian, Adriatic, Aegean and Black seas, the EWC issues advisories on the Tropical like cyclones that form over the area and make landfall over France, Italy and Greece. These systems are supposedly rare phenomena, but over the years they have been increasingly common. In 2013 the European Windstorm Centre decided to extend its basin to include the Mediterranean and Black Seas. These storms tend to form between August and November but If conditions are right can form at any time of the year.
Mediterranean Tropical Cyclone Intensity Scale Edit
In the 2013 the EWC used the Saffir-Simpson Hurricane Scale to measure the intensity of tropical cyclone in the Mediterranean, but this proved unreliable because the categories where to large. In the same year the EWC introduced a second scale Mediterranean Tropical Cyclone Intensity Scale. Tropical Deppression to a Category 2 Tropical Cyclone are split by 10 mph after this to Category 5 Very Severe Tropical Cyclone are split by 5 mph.
