2012 05 22 – Crepuscular Rays and Cloud Shadows
Crepuscular rays are rays of sunlight that appear to radiate from the Sun, forming parallel columns of light that are separated by shadows of clouds or other objects. These rays are made visible by light diffracting and reflecting from particles in the air such as dust or moisture droplets. They are especially beautiful seen through stratocumulus clouds where the cloud shadows appear much darker by comparison and the sky around them is enhanced with beautiful colors of blues and pinks.
The Latin word crepuscular means twilight and the term “crepuscular rays” originates from their occurrences during the dawn and dusk hours.
