Cap Cloud and Lenticular Cloud Formations
January 12, 2017
Shown above is a striking cap cloud hugging Pico de Teide's summit (12,198 ft or 3,718 m), in the Canary Islands (Spain), as observed from Teide National Park. When moist air is forced up mountain slopes it cools and then condenses, sometimes forming a mushroom shaped cloud over the summit. Note the lenticular cloud on the lee side of Teide's flank (at left center). These impressive clouds take shape in mid-level atmospheric waves, downstream of topographic barriers.
