Actinoform Clouds – FYFD

Two flower-like actinoform clouds and two von Karman vortices appear in the cloud cover in this satellite image.

Flower-shaped actinoform clouds, like these seen on the left aspect of this satellite tv for pc picture, had been solely found within the Sixties as soon as satellite tv for pc imagery allowed meteorologists to determine cloud constructions that had been too massive to acknowledge from the bottom. Typically showing over the ocean, these clouds can stretch over lots of of kilometers, bringing drizzling rain.

This explicit set of actinoform clouds have some distinctive neighbors in the best aspect of the picture, the place V-shaped slashes by means of the cloud cowl mark the origins of two von Karman vortex streets. The vortex streets seem downwind of two rocky islands, Alejandro Selkirk Island and Robinson Crusoe Island. (Picture credit score: L. Dauphin; by way of NASA Earth Observatory)
