Categorization of minimum error forecasting zones using a geostatistic wind model

Abstract

In this paper a geostatistic wind direction model is applied to trace a wind speed map, based on data from official measurement weather stations distributed within the region of Andalucia-Spain. Each station's performance is assessed by comparing real measurements to those resulting from the linear interpolation of the rest. Once an error is associated to the station, the error is drawn in a map, in which minimum error zones can be delimited. Frequency and wind speed in each direction are the magnitudes of interest to get a first categorization of wind resources associated to the region. The interest of the method relies in the possibility of forecasting everywhere within the region with an error inside the tolerable margins.
