The main purpose of this paper to to propose a standard regional dependence function (SRDF) based on the concepts of semivariogram and especially cumulative semivariogram. In fact, SRDF is a function of regional dependence which decreases with distance. These functions present quantitatively the regional dependence of the wind phenomenon recorded at irregularly scattered sites over an area. The SRDF provides a unique opportunity for the establishment of a regional objective prediction method whereby the wind velocity and/or energy can be predicted by use of the weighted averages. The weightings are obtained through the SRDF provided that the distance between two sites is known. The implementation of the proposed methodology is presented for some wind velocity measurement stations in Turkey. For the application the experimental SRDF forms are first obtained from the available data and then these are employed directly in the regional estimation procedure. The reliability of the methodology is measured through the cross validation procedure and it is observed that the procedure is valid with less than 15% error. The same procedure can be used in any part of the world.
