On a windy and exhilarating hike, Heather witnessed the development of this cap cloud, which forms as a stable airstream rises to pass over a peak, cooling as it does so. It is a particular variation of a lenticularis cloud, in which the cloud lies over the mountaintop, rather than downwind from it. This classic example was spotted from the Mount Fremont lookout at Mt. Rainier National Park, Seattle, Washington, US.

A classic example of a cap cloud, a particular example of an altocumulus lenticularis, forms as a stable airstream rises to pass over a peak, cooling as it does so. Deborah's son, Peter, spotted this unique cloud formation over what appears to be Mt. Adams as he was on a plane coming in to land at Portland, Oregon, US

These lens-shaped orographic wave clouds, known as altocumulus lenticularis, form when the air is stable and winds blow across hills and mountains from the same or similar direction at different heights through the troposphere. If there is enough moisture in the air, the rising motion of the wave will cause water vapour to condense, forming the unique appearance of lenticular clouds. This classic example was spotted near Narbonne, France.
