Wind Trends Bulletin
In the fi nal quarter of 2013, winds
were generally below normal relative
to the long-term fourth quarter
average (1988 – 2012) 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 Pacifi c 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 Wind Trends Bulletin 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 1988 – 2012 mean speed at 100m above ground level for the calendar quarter.
