Stacked lenticular east of the Cascades

When stable air flows over mountain ranges, the flow can oscillate with stacks of lens-shaped clouds forming in the rising areas of the motion. The image below shows a simplified diagram of this.


Note that there’s also turbulent air closer to the surface. These gusty downslope winds are not uncommon in this scenario and in fact, Jerry Tangren, who sent the beautiful lenticular photo posted above, noted that area was under a high wind warning that day. East Wenatchee is located just to the east of the Cascades in Washington State, creating a prime location to view these beautiful wave clouds as stable flow comes in at mid-levels off the Pacific.
