Masi Nubi iridescenti 2

Summary Author: Alessandra Masi

The iridescent clouds shown above painted the late day sky spectacularly over the peaks of the Dolomites. When sunlight interacts with tiny water droplets in thin clouds (most often mid-level clouds), diffraction processes may result in iridescence. In essence, interference of sunlight around the outside of similar-sized droplets causes overlapping orders of colors, creating the pastel hues. Photo taken on January 15, 2024, at 4:30 p.m. local time.
