dc.description.abstract | We analyse recent trends and variability of observed near-surface wind speed from 19 stations across Saudi Arabia (SA) for 1978–2013. The raw wind speed data set was subject to a robust homogenization protocol, and the stations were then classified under three categories: (1) coast, (2) inland and (3) mountain stations. The results reveal a statistically significant ( p < 0.05) reduction of wind speed of − 0.058 m s − 1 dec − 1 at annual scale across SA, with decreases in winter ( − 0.100 m s − 1 dec − 1 ) and spring ( − 0.066 m s − 1 dec − 1 ) also detected, being non-significant in summer and autumn. The coast, inland and mountain series showed similar magnitude and significance of the declining trends across all SA series, except for summer when a decoupled variability and opposite trends of wind speed between the coast and inland series (significant declines: − 0.101 m s − 1 dec − 1 and − 0.065 m s − 1 dec − 1 , respectively) and the high-elevation mountain series (significant increase: + 0.041 m s − 1 dec − 1 ) were observed. Even though wind speed declines dominated across much of the country throughout the year, only a small number of stations showed statistically significant negative trends in summer and autumn. Most interestingly, a break in the stilling was observed in the last 12-year (2002–2013) period ( + 0.057 m s − 1 dec − 1 ; not significant) compared to the significant slowdown detected in the previous 24-year (1978–2001) period ( − 0.089 m s − 1 dec − 1 ). This break in the slowdown of winds, even followed by a non-significant recovery trend, occurred in all seasons (and months) except for some winter months. Atmospheric circulation plays a key role in explaining the variability of winds, with the North Atlantic Oscillation positively affecting the annual wind speed, the Southern Oscillation displaying a significant negative relationship with winds in winter, spring and autumn, and the Eastern Atlantic negatively modulating winds in summer. | es_ES |
