Wind stilling over the continents of the Northern Hemisphere
A study published on 17 October 2010 in the journal Nature Geoscience shows that over the past three decades, surface wind speeds seem to have noticeably decreased in several regions of the world, such as the United States, China, Australia, and in several European countries. Given the often inadequate quality and heterogeneity of wind data measured by anemometers, no long-term study of the evolution of wind speeds on a global scale had been carried out so far.
