Since global reanalysis datasets first appeared in the 1990s, they have become an essential tool to understand the climate of the past. The wind power industry uses those products extensively for wind resource assessment, while several climate services for energy rely on them as well. Nowadays various datasets coexist, which complicates the selection of the most suitable source for each purpose. In an effort to identify the products that best represent the wind speed features at turbine hub heights, five state‐of‐the‐art global reanalyses have been analysed: ERA5, ERA‐Interim, the Japanese 55‐year Reanalysis (JRA55), the Modern Era Retrospective Analysis for Research and Applications‐2 (MERRA2), and the National Centers for Environmental Prediction (NCEP)/National Center for Atmospheric Research (NCAR) Reanalysis 1 (R1). A multi‐reanalysis ensemble approach is used to explore the main differences amongst these datasets in terms of surface wind characteristics. Then, the quality of the surface and near‐surface winds is evaluated with a set of 77 instrumented tall towers. Results reveal that important discrepancies exist in terms of boreal winter seasonal means, interannual variability (IAV), and decadal linear trends. The differences in the computation of these parameters, which are mainly concentrated inland, reach up to the order of magnitude of the parameters themselves. Comparison with in situ observations shows that the ERA5 surface winds offer the best agreement, correlating and reproducing the observed variability better than a multi‐reanalysis mean in 35.1% of the tall tower sites on a daily time‐scale. However, none of the reanalyses stands out from the others when comparing seasonal mean winds. Regarding the IAV, near‐surface winds from ERA5 offer the values closest to the observed IAV.

El presente artículo forma parte de un estudio más amplio llevado a cabo en la Isla de Mallorca, encaminado a determinar las causas principales de obesidad y sobrepeso en adolescentes, así como también establecer diferentes tipos de análisis con la finalidad de comprender y poder promover intervenciones para aumentar los niveles de actividad física en esta población, ya que tanto el sedentarismo como una mala alimentación son las causas principales de sobrepeso. El caso concreto que se expone se centra en analizar los siguientes aspectos: la relación entre el nivel de estudios de los padres/madres y la obesidad de sus hijos/as, el nivel socioeconómico de las familias y su incidencia en el sobrepeso/obesidad de los hijos/as y, finalmente, la relación entre el tipo de deporte practicado por los hijos/as (federado/no federado) y el sobrepeso/obesidad. Para ello se encuestaron a 4135 niños y niñas de Mallorca. La muestra se obtuvo a partir de un muestreo polietápico. El instrumento utilizado fue un cuestionario de elaboración propia. Los resultados muestran como el nivel de estudios y socioeconómico de los padres, así como el tipo de deporte practicado por sus hijos son variables que favorecen la aparición del sobrepeso y la obesidad en la adolescencia. Palabra clave: Adolescencia, sedentarismo, obesidad, actividad física, nivel socioeconómico, nivel de estudios, deporte.Abstract: This article is part of a larger study carry out in the island of Majorca, which aims to identify the major causes of obesity and overweight in adolescents, as well as to establish different types of analysis in order to understand and to promote interventions to increase physical activity levels in this population, as both a poor diet and sedentary lifestyle are the main causes of overweight. In this case we focus on the following aspects: the relationship between educational level of parents/mothers and their children’s obesity, socioeconomic status of families and its impact on overweight/obesity children and, finally, the relationship between type of sport practiced by the children (competitive sport/ non-competitive sport) and overweight/obesity. To this end surveyed 4135 boys and girls from Majorca. The sample was obtained from a multistage sampling. The instrument used was a specifically designed questionnaire. The results show that educational level and socioeconomic status of parents as well as the type of sport practiced by their children are variables that favor the development of overweight and obesity in adolescence.Key words: Adolescence, sedentary lifestyle, obesity, physical activity, socioeconomic status, level of education, sport.

A dataset containing quality-controlled wind observations from 222 tall towers has been created. Wind speed and wind direction measurements covering the 1984-2017 period have been collected from existing tall towers around the world in an effort to boost the utilization of these non-standard atmospheric datasets, especially within the wind energy and research fields. Observations taken at several heights greater than 10 m above ground level have been retrieved from various sparse datasets and compiled in a unique collection with a common format, access, documentation and quality control. For the last, a total of 18 quality control checks have been considered to ensure the high quality of the wind records. Non-quality-controlled temperature, relative humidity and barometric pressure data from the towers have also been obtained and included in the dataset. The Tall Tower Dataset (Ramon and Lledó, 2019a) is published in the repository EUDAT and made available at https://doi.org/10.23728/b2share.136ecdeee31a45a7906a773095656ddb. J.

El presente trabajo retoma y actualiza las relaciones entre sexo y ansiedad en los deportes de competición. Se analizan las relaciones existentes entre el sexo, la ansiedad competitiva y el tipo de deporte practicado. Se han estudiado 126 deportistas federados de ambos sexos (43 nadadores y 83 baloncestistas), con una edad media de 14.85 años (DE= 2.41), durante la temporada 2013-14, a los cuales se les administró la versión adaptada al español de la Escala de Ansiedad Competitiva (SAS-2). Los resultados muestran que existe un nivel mayor de ansiedad competitiva en las mujeres que en los varones, de forma similar a hallazgos anteriores, aunque los resultados también indican diferencias entre deportes individuales y colectivos, así como diferencias entre los valores de los tres componentes de la ansiedad competitiva: somática, promotora de desconcentración y de preocupación por el rendimiento. Así, las mujeres muestran una mayor preocupación por el rendimiento y ansiedad somática que los hombres. Finalmente, se discuten los resultados en función de otros hallazgos y del concepto multidimensional de la ansiedad competitiva.Abstract. The relationship between gender and anxiety in competitive sports has been taken up and updated by this research. In fact, we analyzed the relation between gender, anxiety, and sports modalities. The study sample was composed by 126 federated female and male athletes (43 swimmers and 83 basketball players), with a mean age of 14.85 years (SD=2.41), during the season 2013-14. Athletes were administered the Spanish adapted version of Sport Anxiety Scale-2 (SAS-2). In line with previous findings, our results show that female athletes have higher competitive anxiety than their male colleagues. In addition, differences were found between individual and team sports, as well as comparing the values of the three components of competitive anxiety: somatic, lack of concentration, and concerns about performance. Women show greater concern about their performance, as well as higher somatic anxiety than men. Finally, the results are discussed and compared with other findings and with the multidimensional concept of competitive anxiety.
