What is the Fohn Effect?
Tuesday 28th February saw some exceptionally mild weather along eastern coasts of Scotland and northern England, and it's all thanks to a weather phenomenon known as the Fohn Effect.
Dyce in Aberdeenshire reached 17.2C, only just missing breaking the all time February record for Scotland of 17.9C in Aberdeen back in 1897.
One record was broken however, as Durham reached 17.4C, making it the mildest February temperature for the city since records began in 1880.
BBC Weather's Chris Fawkes explains what the Fohn Effect is and how it's helped to produce such unusually high February temperatures.
