Abstract

Estimation of wind speeds and direction a few days in advance is of importance for optimum use of wind-power. Numerical weather prediction models now have sufficient skill and can be used for making short-term forecasts. A proper assessment of the model skill at specific ground stations is required before their use. Using the Varsha GCM of CSIR-NAL, a study has been carried out comparing the simulations with observed winds at a few ground stations in Karnataka. A quantification of the accuracy of the forecast is made in this paper. We find that the model captures the overall trends in wind during a day well. The correlation with observations is reasonable up to three days in advance.
