Iridescent Skies at Dusk

 Iridescent Skies at Dusk 

A rare burst of color unfurls across the evening sky as high-altitude clouds scatter sunlight into flowing ribbons of gold, teal, and violet. This phenomenon—known as cloud iridescence—occurs when sunlight diffracts through tiny, uniform ice crystals, separating light into smooth, painterly bands rather than a sharp rainbow.

Strong wind shear stretches the clouds into sweeping curves, turning invisible atmospheric motion into visible structure. light, ice, and turbulence briefly aligned.
