Variations in Monthly Maximum Gust Speed at St Mary's, Isles of Scilly (UK)
Long-term variations in maximum gust speeds have been analyzed using wind measurements recorded at St Mary's, Isles of Scilly, UK, and possible drivers of recent changes have been investigated. A rigorous homogenization procedure has been applied to the wind records to remove discontinuities ma...

Long-term variations in maximum gust speeds have been analyzed using wind measurements recorded at St Mary's, Isles of Scilly, UK, and possible drivers of recent changes have been investigated.

A significant (p < 0.10) decreasing trend of −0.102 m s −1 /10 years is exhibited by the annual maximum gust speeds over the period 1928–2011, while a non-significant (p > 0.10) positive trend characterizes the entire period 1928–2020 of wind measurements.
