1 Q Global Wind Anomalies In the final quarter of 2013, winds were generally below normal relative to the long-term fourth quarter average ( ) across western North America, Central America, the Mediterranean and Black Seas, and central portions of Asia and Africa. Winds were above normal across northwest Canada, the Arabian Peninsula, India, and the northern portions of South America, Europe, and Asia. Changes in global atmospheric circulation drove two dominant wind speed anomaly features of the fourth quarter. Persistently high pressure over the North Pacific was associated with below-normal wind speeds along the western coast of North America. Meanwhile, the Arctic Oscillation index transitioned from neutral to strongly positive, indicative of a more northerly European winter storm track. This brought stronger than average winds to northern Europe and depressed winds in the Mediterranean. Elsewhere, strongly positive wind speed anomalies persisted over northern South America and areas of the Middle East. In India, positive wind speed anomalies spread from the southern states to include most of the country. The is a free report that evaluates deviations in global wind conditions from the historical norm on a quarterly basis. The maps contained in this report were derived from the ERA- Interim reanalysis dataset (Dee, D.P., et al, 2011). The anomalies are calculated as a percent deviation from the mean speed at 100m above analyses for your project portfolio, data or subscription options, please contact us at info@.
