Lenticular Clouds Over the Southern Patagonian Ice Field
March 29, 2017
Shown above is a display of lenticular clouds observed on the footpath to Cerro Torre near the Southern Patagonian Ice Field in Santa Cruz, Argentina. When moisture-laden air is forced to rise over topographic barriers atmospheric waves often form. Smooth, lens-shaped clouds will sometimes take shape on the lee side of the barriers, in the crest of the atmospheric wave. Since lenticulars (Altocumulus lenticularis) typically form in stationary air currents within the wave, they may remain in almost the same position for hours before dissipating.
