In this contribution, we calibrate the meteorological model weather and research forecasting (WRF) for operational forecasting in the Port of Huelva managed by the Authority Port of Huelva. Meteorological forecasting will allow reducing the impact of the meteorological phenomena over weather sensitive activities in the region. Concretely, the meteorological modeling developed will be used to analyze meteorological hazard impacts and to improve the management of the local air quality. To achieve these goals, numerous sensitive analyses corresponding to different model options have been developed. These analyses consider different physical and dynamical options, the coupling of very high resolution physiographic database (topography and land uses), and data assimilation. Comparing experiments, results with observational measures provide us by the Spanish National Meteorology Agency (AEMET). During a representative period, the optimum WRF configuration for the region is obtained. Calibration has been focused on wind due to this is the main risk factor in the region. When the model is satisfactorily calibrated, WRF is evaluated using whole modeling years 2012 and 2013, working with very high horizontal resolution, up to 0.333 km of horizontal grid resolution. Results obtained from the evaluation indicate that the numerical weather prediction system developed has a confidence level of 70% for the temperature, 81% and 66% for the wind speed and wind direction respectively, and 90% for the relative humidity. Methodology designed defines the quality control assurance of high-accuracy forecasting services of Meteosim S.L.

Atmospheric and Climate Sciences 2016年第3期6卷 445-474页

作者： Josep Maria Solé Raúl Arasa.miquel Picanyol Mª Ángeles González Anna Domingo-Dalmau Marta Masdeu Ignasi Porras Bernat Codina Technical Department Meteosim S.L. Barcelona Spain Department of Astronomy and Meteorology University of Barcelona Barcelona Spain

The present study has generated and analyzed Climate Change projections in Nicaragua for the period 2010-2040. The obtained results are to be used for evaluating and planning more resilient transport infrastructures in the next decades. This study has focused its efforts to pay attention into the effect of Climate Change on precipitation and temperature from a mean and extreme event perspective. Dynamical Downscaling approach on a 4 km resolution grid has been chosen as the most appropriate methodology for the estimation of the projected climate, being able to account for local-scale factors like complex topography or local land uses properly. We selected MPI-ESM-MR as the global climate model with the best skill scores in terms of precipitation and temperature in Nicaragua. MPI-ESM-MR was coupled to a mesoscale model. We chose WRF mesoescale model as the most appropriate regional model and we optimized their physical and dynamical options in order to minimize the model uncertainty in Nicaragua. For this, model output against the available in-situ measurements from the national meteorological station network and satellite data were compared. Climate change signal was estimated by comparing the different climate statistics calculated from a model run over an historical period, 1980-2009, with a model run over a projected period, 2010-2040. The obtained results from the projected climate show an increase of the mean temperature between 0.6°C and 0.8°C and an increase of the number of days per year with maximum daily temperatures higher than 35°C. Regarding precipitation, annual projected amounts do not change remarkably with respect to the historical period. However, significant changes in the distribution of the precipitation within the wet period (May-October) were observed. Moreover, an increment between 5% and 10% of the number of days without precipitation is expected. Finally, Intensity-Duration-Frequency (IDF) projected curves show an increment of the rainfall

“Jaleo”是西班牙单词，意为热闹、欢快、喧哗、嘈杂，但这里表达的是一种积极、喜庆、祥和的氛围，这也正是本案餐厅室内设计所要营造的效果。此外，Jaleo这个单词首字母“J”颇为巧合地与餐厅所有者Jose Andres名字的首字母相同，因此此餐厅的设计更富有意义及个性。新Jaleo餐厅的设计灵感源于西班牙传统小吃餐前点心。早在18世纪，当时小酒馆的守门人通常喜欢拿一块面包盖住酒壶壶口，以防止灰尘和飞虫落入，

空间-时间替代的概念被广泛应用，但在地貌学领域还未得到彻底检验。本研究的目的是为了验证空间．时间替代原理对被动进积陆缘的海底峡谷-水道体系演化的重建是否有效。我们利用在南埃布罗陆缘采集的多波束回声探测及原位测量数据，根据递增的河谷谷道长度，分析了一系列的海底峡谷地貌和地形。通过分析，我们提出的海底峡谷演化模型同文献中给出的模型非常相近，由此我们认为在对南埃布罗陆缘海底峡谷．水道体系演化进行重建时，可以运用空间替代时间。根据从空间-时间替代模型应用资料中提取的地形信息，我们识别了被动进积陆缘中海底峡谷演化过程中的一系列地貌类型。这些类型考虑了峡谷平面形态的相似性、峡谷排水效率的增加以及侧面边坡破坏的影响，以及峡谷形态与不发生净侵蚀或沉积作用的附加和悬移质水载荷之间的均衡演化。我们还发现峡谷向下坡的延伸更多，而且峡谷早期经历了同陆相河流的“侵蚀变窄”过程相似的快速下切阶段。我们证明了该研究结论不仅适用南埃布罗陆缘的海底峡谷，也适用于世界上的其它陆缘。

Purpose: Adenosine stress CMR is commonly used to assess myocardial ischaemia. Obtaining high quality images requires maximising signal to noise ratio (SNR) over a large double-oblique field of view (FOV) whilst minimising artefacts. A 32-channel surface coil may provide a higher SNR over a larger FOV compared to standard coils, possibly leading to improved image quality. Materials and Methods: 50 adenosine perfusion CMR scans were performed on a Philips Achieva CV 1.5T, with either a 5 or 32-channel coil (25 patients each) using standardised acquisition protocols. 3 short axis slices were acquired per cardiac cycle and the resulting cine images were scored by two blinded CMR specialists on a quality scale of 1 to 5. Phantom studies were performed using similar acquisition parameters and the SNR was calculated and compared across a range of acceleration factors. Results: The mean patient age was 62 ± 11 years and 50% of patients were male. The image quality scores were higher using the 32-channel coil (mean 3.8 ± 0.7 vs 3.2 ± 0.9 p = 0.002). The average phantom SNR was greater for the 32-element coil across the range of acceleration factors measured (103 vs 86 p = <0.001). Conclusions: The 32-channel coil produces significantly higher quality images and a higher SNR than the 5-channel coil in routine perfusion CMR.

作为一个追求最终产品标准化的行业,生猪在屠宰时的体重变异度目前仍然是养猪业的一个重大课题。生产者经常讨论＂平均体重＂,好像整批猪就只有1头。因此,整批猪会在平均体重达到最优屠宰体重时进行销售。
