New York-based AWS Truepower LLC has released a redesigned and expanded version of its Wind Trends Bulletin – a free quarterly report that examines deviations in global wind conditions from historical norms.
The first-quarter 2013 (Q1'13) bulletin has expanded from Europe, India and North America to include South America, Africa, the Middle East, Asia and Oceania. In addition to including new regions, AWS Truepower says it has updated its methodology in creating the anomaly maps to improve global accuracy.
The AWS report notes the wind speed anomalies in North America during Q1'13: Areas with below-average winds included the coastline of British Columbia and the western U.S., the northern Canadian territories, South Florida, and the Lesser Antilles. Areas with above-average winds include the north slope of Alaska, the Canadian Maritimes, and Mexico, especially Baja California and the Isthmus of Tehuantepec.
Other key Q1'13 findings include the following:
– Winds were generally below normal across the northern latitudes of North America and Eurasia, the west coast of the U.S., the Sahara region of Africa, southern Argentina and Chile, and New Zealand.
– Winds were well above normal across southern Europe and North Africa, as well as in southern Africa, eastern Australia and most of South America.
– The largest wind speed anomalies of the quarter – both positive and negative – were found in Europe and North Africa, a pattern that can be explained in part by the Arctic Oscillation.
