The clouds appeared in a stack above Egremont
Eerie lenticular clouds were seen in parts of Cumbria at the weekend.
Often mistaken for UFOs, the unusual formations form near mountains when the air is both stable and humid. As air is blown over the mountain, it produces a standing-wave pattern and these clouds form in the crest of the waves. If the airflow is particularly strong, the cloud wave can form into layers, creating impressive stacked lenticulars.
Lenticular clouds appear to hang motionless in the sky even when it's windy. In fact water droplets are racing around the cloud, carried by the wind. It's just the points where they condense and evaporate that are fixed, creating a well-defined stationary cloud.
