Tornado and Rainbow Over Kansas - A white tornado cloud descends from a dark storm cloud. The Sun is peeking through a clear patch of sky to the left. Sunlight reflects off raindrops to form a rainbow. In an amazing spectacle, the tornado appears to end right over the rainbow. Streaks in the image are hail being swept about by the high swirling winds. – på lmage Credit: Eric Nguyen/Oklahoma U./NASA ('04).
