Portugal

In Portugal, 2012 was an atypical year in Portugal with regards to energy. Due to the efficiency measures implemented in recent years, but also due to the economic recession, electricity consumption in Portugal dropped 3.6% to 49.1 TWh. This represents a reduction of 6% of electricity demand in the last two years (1). It was also an extremely dry year, the fifth driest hydro year of the past 80 years (63% below...

Validation of an offshore wind atlas using the satellite data available at the ...

In this study a validation methodology for regional mesoscale model simulations when ingested with surface wind data inferred from satellite sources around Continental Portugal is evaluated. Observational wind data from a “quasi” offshore anemometric mast located in the Berlenga Island – near Peniche region – was used for the validation study. Satellite sources of wind data under assessment are the ones being u...

Uma Complicação Grave da Embolização das Artérias Uterinas

Uterine artery embolisation has been used as a therapeutic alternative for symptomatic uterine myomas. It is considered a safe and effective procedure, with very few cases published involving complications. The authors present a case of a 35-year-old nulliparous woman with an intramural myoma with 161x143x85mm, submitted to an uterine artery embolisation complicated by uterine necrosis. A hysterectomy was perfo...

Using data assimilation in mesoscale numerical modeling to map offshore wind re...

data from GHRSST Level 4 analysis have been ingested to an atmospheric mesoscale numerical model using a Newtonian relaxation assimilation technique. The mesoscale model WRF was used to map the wind resource at 90 m a.g.l. for the North Sea area. A model domain with a spatial resolution of 20x20 km was used to simulate a winter and a summer month, November 2008 and July 2009. The modeled wind results have been ...

Impact of weather conditions on the windows of opportunity for operation of off...

The deployment of offshore wind parks face several challenges. Among them are the difficulties introduced by the atmospheric and sea conditions in accessing those wind parks. A window of opportunity is a timeframe when weather and sea conditions are acceptable and enable to perform specific tasks in the installation and operation/maintenance of the offshore wind park. This study identifies typical time period...

Portugal

During 2011, Portugal experienced a strong reduction of electricity demand. With a decrease of 2.3%, the total consumption was 50.5 TWh (1). Due to a mild winter season, the most relevant renewable generation facilities (hydro and wind) experienced a strong production reduction in comparison with 2010. In 2011, Portuguese wind farms produced 21 GWh less than the previous year. It is only because of the decrease...
