- Storm Ciara has caused extensive damage in Europe.
- After first sweeping across Ireland and the UK on 9th February, the storm thrashed the north coast of mainland Europe.
- Belgium, Britain, France, Germany, and Poland
- Storm Ciara is notable because of the very strong and widespread winds(~150 kph).
Why multiple names ?
- The storm has multiple names because there isn’t yet a pan-European system in place for labelling weather systems.
- Sabine in Germany
- Ciara in UK
- Elsa by Norway
What kind of storm?
- Storm Ciara is an active extratropical
- Temperate cyclones are also known as Extra-tropical
- “Extra-tropical” signifies that this type of cyclone generally occurs outside the tropics with a latitude range between 30° and 60°.
Extra tropical Cyclones
- Extra-tropical cyclones are also known as mid-latitude storms or baroclinic storms.
- In the Northern hemisphere, cold air blows from the north of the front and warm air blows from the south.
- When the pressure descents along the front, the cold air move towards the south and the warm air moves northwards setting in motion an anticlockwise cyclonic circulation.
- The cyclonic circulation results in a well-built extratropical cyclone, with a cold front and a warm front.
- The storm developed over the Atlantic Ocean “in interaction with a strong” jet stream, which consisted of winds running at about 249 miles per hour.
- The jet stream behaves like a giant vacuum cleaner which can sometimes dig deep areas of low pressure, until creating storm depressions
- Transport shut down – Flights, trains, roads
- Ferry services stopped
- Schools were forced to close across Northern Europe
- Extensive damage to buildings and infra in coastal areas
- Storm surge and Flooding
- The powerful gusts of wind did bring one unexpected benefit in Germany.
- Wind turbines there produced a record amount of electricity, reportedly equivalent to 44 nuclear power plants.
- A passenger plane travelling from New York to London made the trip in four hours and 56 minutes by riding a jet stream that was accelerated by the storm.
