When I told my father that I would like to jump out of the plane and land in the clouds when I was little, he said, "If you really want to be in a cloud, go outside the next time we have a foggy morning, and you will be walking in a cloud!" Fog is simply a cloud that touches the ground. This photo was taken as we flew along the central coast of California in June 2006. Fog is a nearly daily event along the California coast during the summer because of the warm air inland and the cold, moisture-laden air over the ocean. The fog usually "burns off" around 10 AM then returns late in the afternoon.
