Abstract
The purpose of this paper is to estimate the average wind speed in some parts of Jordan using a standard regional dependence function (SRDF) based on the concept of the point cumulative semivariogram (PCSV). The SRDF method provides weights for different regional sites depending on the distance from the pivot site. The closer the site the larger are the weights of the site, and these weights are used as predicting tools. This method gives reliable results in estimating wind speed in Jordan during most months in the year, except in summer. The method can be used also in determining the borders between different wind regimes. The PCSV and SRDF graphs explain the transition zones between the climatic regions of Jordan.
