Lofted Fog Phenomenon
The Lofted Fog Phenomenon is frequent, seen over sections of the mountains or the urban city. It can cover the entire city or a mountain range at one time or occur in more readily delineated patches as seen here. The fog is undoubtedly a mix of air pollution smoke particles thus creating smog. When moisture or rain is present, the patch takes on a greater content of mist. These patches move as quickly as fast moving clouds, usually appearing then gone in 20 minutes. In the photo above, the patch appeared and was gone in 20 minutes.
