The Storm

  • 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.
  1. Sabine in Germany
  2. Ciara in UK
  3. 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.
  1. Direction
  2. Duration
  3. Intensity
  • 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

Damage

  • 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

Unexpected benefits

  • 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.
