I have been fascinated by clouds all my life. Some of my earliest memories involve looking up at clouds, when I was young wondering what they were.

Clouds are described by their height and by their form. I find the height sometimes difficult to judge.

Who can resist a good sunrise or sunset?
And some clouds are just disturbing.
