[edit] Summary

Description

Contrail that looked strangely strangely similar to the tsunami warning sign, which is seen at w:street light below, San Francisco, California. This contrail is example of w:Crow instability. w:Crow instability is an inviscid line-w:vortex instability, named after its discoverer S. C. Crow. It is observed when the vortices caused by aircraft are being whirled from being otherwise straight contrails into spirals then donut-shaped rings.
