Lee waves. These are internal gravity #waves revealed by the #clouds. They are generated as slightly denser air parcels are pushed up (where the air is less dense) as the wind blows over a obstacle like a #mountain. Then, as the air parcel is heavier than its surroundings, it sinks and overshoots. That is how the wave #oscillation is started.
I shot this while in the #Pyrenees last week, a #timelapse condensing 5 minutes into 15 seconds.
