Tendencias de la brisa marina en el este de España, 1961-2019
[EN]: Most studies on wind stilling and its recent reversal have been addressed at global scales, while changes according to the type of wind have not yet been quantified; e.g. westerlies, local winds, sea breezes, among others. Recent studies over the Iberian Peninsula suggest a hypothetical reinforcement of sea breeze speeds in summerautumn. Here, we developed an automated method for the detection of sea breeze episodes on sub-daily wind observations from 16 weather stations across eastern Spain. After identifying 9.312 days of sea breezes, we analyzed trends and multidecadal variability on their speeds, gusts and occurrence for 1961-2019. We found a decoupled variability between the sea breeze speeds and gusts: the speed declined in most time-scales (excepting winter) while gusts strengthened annually and in autumn-winter. We also found an increased winter occurrence of the sea breeze, which variability is partly explained by more frequent anticyclonic conditions. The causes behind the opposing trend in the speed and gusts remain unclear, requiring further investigation. This work fills a gap in the knowledge of the long-term variability of the Mediterranean Sea breezes and the drivers of seasonal changes in surface winds.
