Two research scientists have created an animated map of wind patterns across the continental U.S. that changes with hourly forecasts. The Web-based map (hint.fm/wind) taps into a National Weather Service database that provides wind forecasts for roughly every two square miles in the U.S. Against a black background that's free of state boundaries or geographic detail, delicate white lines representing wind move across the land—they swirl, collide, cascade, subside. Viewers checking out the map in its first week online could see ominous whorls in Texas; soon after that, tornadoes struck there. The creators of the map work for Google's Big Picture visualization-research group.
