Days of gale each year


Figure 44 - Days of gale each year for three Scottish stations - Lerwick, Tiree, and Leuchars, 1957 to 2004, with smoothed curves showing a running average.

Regional trends


  • The exposed island sites of Lerwick and Tiree experience a higher number of gale days in a year than Leuchars.
  • The year to year changes are also higher for the island sites but there is no clear trend in any of three records.

Future trends


  • The UKCIP02 scenarios report does not give estimates for this specific measure, but estimates for changes to average wind speeds are small.
  • Confidence in any estimate for this variable is very low.
