11th of May, 2016 Roberto Porto observed in the Teide National Park (Tenerife, Spain) wunderful fogbows in top of a deeper cloud layer. The moderate climate of Tenerife is controlled to a great extent by the tradewinds, whose humidity is condensed principally over the north and northeast of the island, creating cloud banks that range between 600 and 1,800 metres in height. If moves out of the cloud layer as far as you can see the sun, one has with the sun behind the best observing conditions for a fog bow.
As the name might suggest, a fogbow is the name given to a phenomenon created by the same process of refraction and reflection that creates rainbows, but formed instead by the water droplets in fog, mist or cloud, rather than raindrops.
The timelapse video show 3 different fogbows in the sea of clouds of Volcano Teide. The sun low in the horizon produced the beautiful fogbows.
