Description

This article is from the sci.fractals FAQ, by Michael C. Taylor and Jean-Pierre Louvet with numerous contributions by others.

36 What are plasma clouds?

They are a Fractint fractal and are similar to fractal
mountains. Instead of a 2-d table of heights, the result is a 2-d
table of intensities. They are formed by repeatedly subdividing
squares.

Robert Cahalan has fractal information about Earth's Clouds including
how they differ from plasma clouds.

Also some plasma-based fractals clouds by John Walker are available.

The Center for the Computation and Visualization of Geometric
Structures also has some fractal clouds.

Two articles about the fractal nature of Earth's clouds:

1. "Fractal statistics of cloud fields," R. F. Cahalan and J. H.
Joseph, "Mon. Wea.Rev." 117, 261-272, 1989
2. "The albedo of fractal stratocumulus clouds," R. F. Cahalan, W.
Ridgway, W. J. Wiscombe, T. L. Bell and J. B. Snider, "J. Atmos.
Sci." 51, 2434-2455, 1994
