Sometimes amazing atmospheric phenomena can be observed over the mountains near my home in Pissonas, Greece. This eye-catching lenticular cloud formation could be seen over Mount Dirfys (5,719 ft or 1,743 m), at left center, and Mount Xirovouni, at right center, during the late afternoon of February 13, 2018. Lenticular clouds (Altocumulus lenticularis) form over elevated terrain, usually in stationary lee waves. As shown above, if the air flow is vigorous and water vapor abundant, layers will begin to build and stack upon one another at the crests of the wave.
