AWS Truepower's first annual report for "Global Wind Speed Anomalies"

AWS Truepower, LLC, announces the release of its first Annual Wind Trends Bulletin, which shows departures in the wind energy resource from the historical norm for 2012 for every region of the world. Such departures, or anomalies, are linked to variations in the output of wind energy projects, and can be a key indicator of the financial performance of these projects. 

The 2012 bulletin shows that winds were unusually good in some areas of the world, including southwestern China, eastern Russia, northern Brazil and Papua New Guinea, whereas in others, such as northern Canada, central Russia, Southeast Asia, and East African Rift region, 2012 was a down year. The historical baseline is 1988-2012, and the source of the data is the ECMWF ERA-Interim reanalysis data set. AWS Truepower has analyzed the data and interpolated them to 100 m above ground height (a common height of modern large wind turbines).

The annual Wind Trends Bulletin is a companion to AWS Truepower's quarterly bulletin, which presents deviations in wind resources for the trailing quarter. Monthly data, and data for specific sites and regions, are available from AWST.
