Trends of daily peak wind gusts in Spain and Portugal, 1961–2014

Given the inconsistencies of wind gust trends under the widespread decline in near‐surface wind speed (stilling), our study aimed to assess trends of observed daily peak wind gusts (DPWG) across Spain and Portugal for 1961–2014 by analyzing trends of (i) the frequency (90th percentile) and (ii) the...

Zusammenfassung:Given the inconsistencies of wind gust trends under the widespread decline in near‐surface wind speed (stilling), our study aimed to assess trends of observed daily peak wind gusts (DPWG) across Spain and Portugal for 1961–2014 by analyzing trends of (i) the frequency (90th percentile) and (ii) the magnitude (wind speed maxima) of DPWG. Wind gust series were homogenized on a daily basis, using MM5‐simulated series as reference, resulting in 80 suitable station‐based data sets. The average DPWG 90th percentile frequency declined by −1.49 d decade−1 (p  0.10), with distinct seasonality: declining in winter (−0.168 m s−1 decade−1; p
