The object, curiously similar to what we fancy ET’s SUV would look like, is a fairly common image in our rainy-season skies.
It’s called a lenticular cloud, and it forms when large standing waves of moist air high in the atmosphere are struck by perpendicular wind, swirled into the shape of a saucer or lens and built up by rising air.
This altocumulus standing lenticularis was captured by Jeanie on the afternoon of Thursday, April 22.
