3TIER has released a wind performance map for the fourth quarter of 2010. The map illustrates that wind speeds were above their seasonal average for large areas across the US. This increase is largely due to the La Niña phenomena.

The actual variance map shows that wind speeds were 5%-30% above their long-term averages across the western and northeastern US and the Great Lakes and eastern provinces of Canada. Most of the Texas wind corridor also saw wind speeds that were about 5% above normal. Meanwhile, much of the upper Midwest and central Canada experienced wind speeds that were 5%-15% below normal.
