From a forecast perspective they indicate a strong flow of wind aloft, and will typically bring a downsloping wind to the Front Range and a big temperature boost. This is not to say that it cannot move vertically; rather, if it is disturbed by some outside force, and displaced vertically, it will not continue to move upward of its own accord.

Cold air turns into liquid water after a certain point. Warm, moist air over low, flatland areas on clear, calm nights. Then, if the temperature at the crest of the wave drops to the dew point, moisture in the air may condense to form lenticular clouds. Sometimes they can be elongated and stretched across the ridgeline of a mountain range. As a result, as the moist air moves back down into the trough of the wave, the cloud may evaporate back into vapor. When unstable air is obstructed by a mountain, it intensifies the turbulence it produces on the windward side and along the crest. Apartments under $800 in delaware / innsbrook golf course dress code / standing lenticular clouds, in mountainous areas, indicate. Since mountain peaks are at higher altitudes, it allows air to become colder.

Similar Answers: Similar Questions: 2-Lenticular clouds in mountainous areas indicate: 050 15025 Clouds and Fog light variable winds. [3], Pilots of powered aircraft tend to avoid flying near lenticular clouds because of the turbulence and sinking air of the rotor generated at the trailing edge of these clouds, but glider pilots actively seek them out in order to climb in the upward moving air at the leading edge. 144 What is an important characteristic of wind shear? When this happens, a series of large-scale standing waves may form on the mountains downwind side. Press Esc to cancel. Lenticular clouds are also known as orographic clouds, which is a fancy word for mountain. This sounding was taken the day that an impressive ACSL cloud was captured on film (below) just north of Gallup and is typical of days when ACSL clouds are present. Sufficient moisture, an unstable lapse rate, and a lifting action. The most telling clue that a mountain wave exists is the presence of ACSL clouds.
