New York Forest.2

Actual Elapsed Time: 2.8 hours (10,000 seconds)

The morning fog lifts as the sun rises on a forest in New York state. The morning fog consists of tiny droplets of water. As the sun warms the air and ground, the small droplets evaporate, becoming invisible water vapor, and the fog disappears. In this clip, sped up 1,000 times, you can also see wind currents moving from the left side of the picture pushing the fog up and away. The movement of shadows marks the passage of the sun across the sky. If you look carefully, you can also see that the color of the sunlight changes from pale yellow to clear blue as the sun rises higher in the sky. This is due to the fact that at sunrise the sunlight must pass through more of the earth's atmosphere. This produces a reddish-yellow cast to the light.
