This issue, the third one of 2009 contains seven papers on a variety of subjects important to wind engineering in general. The first two papers deal with vertical axis wind turbine (VAWT) technology. The lead paper on this subject is by Wakui and co-authors (Yokoyama and Arase) from Osaka Prefecture University in Japan and investigates the influence of load level on the performance of straight-wind VAWTs. The second paper in this group is by Fiedler and Tullis from McMaster University (Canada) and discusses the effects of blade offset and pitch on the performance of a high solidity VAWT. The next pair of papers deals with the general subject of wind forecasting and resource assessment. The first one of these is by Collins, Parkes, and Tindal from Garrad Hassan and deals with short-term wind forecasting for utility-scale wind farms.
