“…While consistent results between DPWG trends and mean near‐surface wind speed trends are reported for the IP several other studies performed in different geographic regions detected differences in the reported trends by analyzing mean wind speed and wind speed maxima [ Klink , ; Vautard et al ., ]. Our IP specific results agree with Cabalar‐Fuentes [] for the northwestern part of the IP. These findings (i.e., agreement of trends for the IP versus contradictory trends reported elsewhere [ Klink , ; Vautard et al ., ] the latter having a focus on the entire northern hemisphere) demonstrate that local‐to‐regional weather systems and teleconnections with synoptic features (e.g., NAOI) are important to understanding wind dynamics for a study site the area of the IP.…”

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 À1.49 d decade À1 (p < 0.05) annually. This showed marked seasonal differences: decreasing in winter (À0.75 d decade À1 ; p < 0.05) and increasing in summer (+0.18 d decade À1 ; p > 0.10). A negligible trend was calculated for the annual magnitude of DPWG (À0.005 m s À1 decade À1 ; p > 0.10), with distinct seasonality: declining in winter (À0.168 m s À1 decade À1 ; p < 0.10) and increasing in summer (+0.130 m s À1 decade À1 ; p < 0.05). Combined, these results reveal less frequent and declining DPWG during the cold semester (November-April) and more frequent and increasing DPWG during the warm semester (May-October). Large-scale atmospheric changes such as the North Atlantic Oscillation Index (negative correlations~À0.4-À0.6; p < 0.05) and the Jenkinson and Collison scheme (positive correlations mainly with Westerly regime:~+0.5-0.6; p < 0.05) partly account for the decadal fluctuations of both frequency and magnitude of DPWG, particularly in winter. However, the North Atlantic Oscillation index-DPWG relationships are smaller in spring, summer, and autumn (~À0.1-À0.2; p > 0.10), especially for the frequency, suggesting the role of local-to-mesoscale drivers.In view of (i) the minimal number of studies reporting long-term changes from observed DPWG over land; (ii) the overall inconclusive nature DPWG trends observed from anemometers; and (iii) the substantial societal and environmental impact of this natural hazard (e.g., for human safety, maritime and aviation activities, engineering and insurance applications, and energy production), additional trend assessments, and studies that assess these trends from a large-scale atmospheric circulation perspective are needed to increase our understanding of wind extremes [Vose et al., 2014]. The principal objective of this study is to determine, for AZORIN-MOLINA ET AL.

“…The fronts arriving at the coastline are uplifted due to the sharp topography of the coastal regions. This generates adverse weather events with intense rainfalls characterized by a high spatial and temporal variability (Cabalar-Fuentes, 2005). This behaviour is also observed in other regions, such as the U.S. Pacific Coast, given the similar latitude and orography (Eiras-Barca, Brands, & Miguez-Macho, 2016).…”

This paper analyses the effect of rain data uncertainty on the performance of two hydrological models with different spatial structures: a semidistributed and a fully distributed model. The study is performed on a small catchment of 19.6 km2 located in the north‐west of Spain, where the arrival of low pressure fronts from the Atlantic Ocean causes highly variable rainfall events. The rainfall fields in this catchment during a series of storm events are estimated using rainfall point measurements. The uncertainty of the estimated fields is quantified using a conditional simulation technique. Discharge and rain data, including the uncertainty of the estimated rainfall fields, are then used to calibrate and validate both hydrological models following the generalized likelihood uncertainty estimation (GLUE) methodology. In the storm events analysed, the two models show similar performance. In all cases, results show that the calibrated distribution of the input parameters narrows when the rain uncertainty is included in the analysis. Otherwise, when rain uncertainty is not considered, the calibration of the input parameters must account for all uncertainty in the rainfall–runoff transformation process. Also, in both models, the uncertainty of the predicted discharges increase in similar magnitude when the uncertainty of rainfall input increase.

“…The main campus area of the University of A Coruña is located in the coastal area of Galicia (NW Spain), a region characterized by a temperate oceanic climate with frequent intense rainfall events and strong winds (Cabalar Fuentes, 2005), where land-use is dominated by a mosaic of intensive agro-ecosystems (agricultural and forest plantations) (Corbelle-Rico and Tubío Sánchez, 2017). The campus is located in the peri-urban zone of the city (29 T 4797271, 547962).…”

Purpose Invasive species are under the spotlight because of their detrimental effects on biodiversity. However, management of invasions presents multiple dimensions frequently difficult to disentangle. This complex topic has been tackled through a service-learning project on an invasive insect (Vespa velutina), a bee-eating species invading Europe. Specifically, this paper aims to assess the educational needs and motivations detected in a local population for the control of V. velutina, and evaluate the educational achievements of students participating in the project. Design/methodology/approach The paper illustrates how students prepared the service activity, which consisted in a quiz and interviews to public in a honey festival located in an area that has invested heavily in the control of the hornet. They informed visitors on its biology and impacts, and collected information on visitors’ knowledge and attitudes towards the hornet. This information was taken back to the class and discussed in an open debate. Findings The service activity uncovered important knowledge gaps of the local population and revealed the attachment to controversial control methods. Students acknowledged that the project met a real community need and valued the contact with the public, and the presentation of the project in the Faculty favored a debate on invasions management and biodiversity protection under the framework of campus sustainability. Originality/value While students are familiar with actions on campus sustainability, they are seldom confronted with the evaluation of management decisions on complex topics involving multiple dimensions. This service-learning project showed a good potential for fostering in-depth debates and promoting student engagement in campus sustainable initiatives.
