You can see surface winds—the stuff you feel, standing there on the surface of the Earth as the mere mortal you are—in white. The bright white circles you see over the Atlantic Ocean and the East China Sea are cyclones. Meanwhile, the colored streaks represent upper-level winds at an elevation about 33,000 feet above the surface of the Earth. The upper-level winds' colors represent their speeds, which range from 0 to 175 meters per second (a little more than 390 miles per hour). The red winds are the fastest.
