Interannual variability of the average wind speed in Europe

Interannual variability of the average wind speed is the main factor for erroneous annual wind park production estimates and therefore can cause serious economic problems to wind park promoters from lower income than expected. In this study, the magnitude of interannual variability of the average wind speed is assessed in Europe, based on data sets from NCEP Reanalysis II. The areas with the highest values of i...

Monthly forecasts of the average wind speed in Portugal

Forecasts of the monthly anomaly of the average wind speed can provide useful information for energy management and production. Unlike methods which use state-of-the art highly complex dynamic or statistic models, this study presents a methodology based on analogues. This simple method identifies similar weather patterns using past observations to produce a forecast and relies on the fact that the atmosphere ha...
