STS045-85-024 and STS045-77-078: Low-level Polar Atmospheric
Phenomena STS045-85-024 shows a combination of von Karman eddies
and Kelvin waves. The von Karman eddies are three small circular
features created by boundary layer winds flowing past obstacles
(in this case some of the Aleutian Islands). Capping by a strong
inversion and a saturated atmosphere are requirements for the
development of visible von Karman eddies. Kelvin waves (fish-
wake feature in corner of frame) are curved, more linear features
than the circular von Karman eddies. They indicate regions where
the capping inversion is less strong.
