Wind Map of the United States: Data Visualization

 Two technology artists, Fernanda Viegas and Martin Wattenberg, who head Google's "Big Picture" visualization research group have created a time-lapse animation of wind speeds across the U.S. The surface wind data is from the National Digital Forecast Database, which is downloaded once an hour. 

"An invisible, ancient source of energy surrounds us--energy that powered the first explorations of the world, and that may be a key to the future," the artists have written. "This map shows you the delicate tracery of wind flowing over the US right now."

The black map, simply named "Wind Map," displays white streaks that show varying wind speeds from 1 to 30 miles per hour. The stronger the winds, the more dense the white streaks. As the wind courses across the county, certain patterns emerge, such as swirls around the Rockies and powerful blasts coming off the Great Lakes.
