January 27, 2015 in RMNP at 1:57 PM. Moraine Park… looking west towards Stone's Peak. Amazingly beautiful horsetail clouds and near 70º. It was breathtakingly beautiful, calm and peaceful. Canon 5Dmk3, Canon EF 24-105mm f/4L IS USM, f/16, ISO 100, 1/125s, lens focal length 65mm.
Cirrus uncinus is a type of cirrus cloud. The name cirrus uncinus is derived from Latin, meaning “curly hooks”. Also known as mares’ tails, these clouds are generally sparse in the sky, and very thin.
The clouds occur at very high altitudes, at a temperature of about minus 40-50 degrees Celsius. They are generally seen when a warm or occluded front is approaching. They are very high in the troposphere, and generally mean that precipitation, usually rain, is approaching.
