Specifically, I read: “Lenticular clouds indicate great instability in that layer of the atmosphere, and form in areas of mountain waves. These clouds are reported in the remarks section of hourly sequence reports as ACSL (altocumulus standing lenticular) or CCSL (cirrocumulus standing lenticular). Fair weather cumulus clouds often indicate bumpy turbulence beneath and in the clouds but good visibility. You will usually find standing lenticular clouds near the tops of mountains, however, you can find them many miles downwind from the mountain peaks as well. turbulence. It makes sense that it would be a "rough ride". These clouds also occur in regions lacking mountainous terrain, in areas of turbulence, but are less common. The presence of standing lenticular altocumulus clouds is a good indication of. Definition. In short, energy is produced by air moving over the summit which is then transmitted upward through … Hence, they are known as standing lenticular. If the temperature at the crest of the wave drops to the dew point, moisture in the air may condense to form lenticular clouds.

An almond or lens-shaped cloud which appears stationary, but which may contain winds of 50 knots or more, is referred to as 1. a lenticular cloud. A series of lenticular or standing wave clouds can occur a hundred miles or more downstream. This deflection creates a gravity wave downwind of the topographic barrier not unlike a wave you might generate by throwing a pebble into a pond. When sufficient moisture is present above mountain-top level, ACSL clouds develop within the crest of these mountain waves where the air is rising. AC 00-6A: Term. At the lower levels, moisture may condense on its ascent, blanketing the ridgeline with a cap cloud. (…) It makes sense that it would be a ‘rough ride’. Flying into or around these types of clouds can be very turbulent. 123 Standing lenticular clouds, in mountainous areas, indicate An inversion. Ice pellets encountred during flight normally are evidence that A warm front has passed. In the Boulder area, the obstacle is the Front Range of the Rocky Mountains.
