Kelvin-Helmholtz Wave Clouds Over B'ham

The Kelvin–Helmholtz instability, after Lord Kelvin and Hermann von Helmholtz, can occur when velocity shear is present within a continuous fluid, or when there is sufficient velocity difference across the interface between two fluids. One example is wind blowing over a water surface, where the wind causes the relative motion between the stratified layers (i.e., water and air). The instability will manifest itself in the form of waves being generated on the water surface. The waves can appear in numerous fluids and have been spotted in clouds, Saturn's bands, waves in the ocean, and in the sun's corona.

A History of the Sky

From these images, I created a mosaic of time-lapse movies, each showing a single day. The days are arranged in chronological order. My intent was to reveal the patterns of light and weather over the course of a year.
