In Boca Raton, Florida, US, Ray Popkin (Member 63,500) likes to rise early to watch the interplay of Sun, storm, and sea that often occurs around sunrise.

This dawn began with a veil of precipitation from a powerful Cumulonimbus capillatus incus cloud. Capillatus refers to the hairlike appearance at the top of the Cumulonimbus, indicating that this mature storm cloud has grown tall enough for its upper region to freeze entirely into ice crystals, which gives it a fibrous look. The incus, or anvil shape, is a result of the cloud spreading outwards at the top. Above the Cumulonimbus, a high layer of ice crystals classified as a Cirrostratus fibratus cloud paints pale streaks across the sky. Around about and off on the horizon, turrets of Stratocumulus castellanus backlit by the rising Sun show where pockets of air are rising from the warm sea surface. There is enough energy in this morning sky to enliven the most sluggish of early risers.
