Squarely in Wellington
On Being Absolutely Positive...There are some days when I think I'm going to die from an overdose of satisfaction. - Salvador Dali
Cloud by Salvador DaliMy son, Wolfy, took these pictures. The bottom picture he used to enter the "Postcards from Wellington" contest and won more than $100 in gift certificates from the Camera House. He used them to buy more disposable cameras. I discover that the unusual cloud shown above is a lenticular cloud. Lenticular clouds are typically formed by high winds over rugged terrain and are particularly apparent when few other clouds are in the sky. They can take on particularly strange, layered shapes. Here are three others...

Actually, pictured above are several clouds all stacked up into one striking lenticular cloud. Normally, air moves much more horizontally than it does vertically. Sometimes, however, such as when wind comes off of a mountain or a hill, relatively strong vertical oscillations take place as the air stabilizes. The dry air at the top of an oscillation may be quite stratified in moisture content, and hence forms clouds at each layer where the air saturates with moisture. The result can be a lenticular cloud with a strongly layered appearance. The above picture was taken in 1999 over Plymouth, New Hampshire, USA.

Lenticular clouds can be shaped like a saucer, and can fly in the sense that, like most clouds, they are composed of small water droplets that float on air. Above, a couple stopped their car near Yellowstone National Park in Wyoming, USA to photograph this lenticular cloud behind picturesque windmills.
