Definition. Standing lenticular clouds B. Mammatocumulus clouds C. Roll clouds Radar weather reports are of special interest to pilots because they indicate A. 12 . Lenticular clouds unique to the mountain environment Smooth, lens-shaped clouds above peaks and ridges Indicate strong winds flowing up and through that area There may bean area of severe to extreme turbulence beneath a lenticular cloud. Since air cools as it rises and warms as it falls, lenticular clouds are most likely to form at the peak of a standing wave, where moisture condenses in the cooled air. Figure 81 further illustrates clouds often associated with a mountain wave. very strong turbulence. Cumulonimbus clouds are associated with the greatest turbulence. Lenticular clouds are saucer-shaped clouds that are often witnessed over mountains and mountain ranges. When you suspect any mountain wave activity you should use extreme caution. Fair weather cumulus clouds often indicate. These formations are frequently caused by wave motions in the atmosphere, and are frequently seen in mountains or hilly areas. If enough moisture is present, standing lenticular clouds can form to give a visual indication of the wave action. The lenticular clouds take forms on the top of the mountains; when strong winds hit the mountain, these lens-shaped clouds are forced upward to the atmospheric levels. B 125 Ice pellets encountred during flight normally are evidence that A warm front has passed. when is an airplane most likely to be struck by lightning leave the area of precipitation, if able, or fly Lenticular clouds, technically known as altocumulus standing lenticularis, are stationary lens-shaped clouds that form at high altitudes, normally aligned at right-angles to the wind direction. They are also referred to as lennies in the weather community. Lenticular clouds indicate great instability in that layer of the atmosphere, and form in areas of mountain waves. The cloud base on the leeward side is higher than on the windward side, because precipitation on the windward side removes water from the air. turbulence at and below the cloud level . When you timelapse a lenticular cloud it Winds Through Passes Winds flowing through the narrow restriction Which family of clouds is least likely to contribute to structural icing on an aircraft? The wind on the windward side is pushed up and then pulled back down on the downwind side. 78 Which cloud types would indicate convective turbulence? 123.Standing lenticular clouds, in mountainous areas, indicate A. Standing lenticular clouds, in mountainous areas, indicate? 4132. Mountain waves are the most common form of a gravity wave. very strong turbulence. Very strong turbulence. The waves downwind from the mountain are the "standing wave" or "lee wave." Where stable moist air flows over a mountain or a range of mountains, a series of large-scale standing waves may form on the downwind side. b. Unstable air. What do lenticular clouds predict? B very strong turbulence. C) unstable air. The presence of standing lenticular altocumulus clouds is a good indication of: Definition. In the Boulder, Colorado area, the obstacle is the Front Range of the Rocky Mountains, seen at the bottom of the picture. In mountainous areas, clouds may form lines at an angle to the wind. Nimbus clouds are associated with rain. They are stationary clouds that form at high altitudes. An inversion. Lenticular clouds are also known as orographic clouds, which is a fancy word for mountain. Question: 1 Every physical process of weather is accompanied by or is the result of A. a heat exchange. The crest of the mountain wave is often marked with altocumulus standing lenticular clouds, provided theres sufficient moisture. The lenticular clouds take forms on the top of the mountains; when strong winds hit the mountain, these lens-shaped clouds are forced upward to the atmospheric levels. [Source: Wikipedia] Lenticular clouds indicate great instability in that layer of the atmosphere, and form in areas of mountain waves. These clouds, known as lenticular clouds form above a mountain when a breeze creates a number of standing waves on the downwind side of the mountain. Standing lenticular clouds in mountainous areas indicate turbulence. If the temperature at the crest of the wave drops below the local dew point, moisture in When strong upper winds carry stable but moist air over a mountains, a series of large-scale standing waves forms on the downwind side. In the Boulder area, the obstacle is the Front Range of the Rocky Mountains. C turbulence. 78 Which cloud types would indicate convective turbulence? Clouds resembling long bands of stratocumulus sometimes mark the area of overturning air. These clouds are also an indication of moderate to severe turbulence. Pixabay Standing lenticular clouds over a mountain ridge. 87 The conditions most favorable to wave formation over mountainous areas are a layer of 123 Standing lenticular clouds, in mountainous areas, indicate An inversion. Standing lenticular clouds, in mountainous areas, indicate, Fog is usually prevalent in industrial areas because of, an abundance of condensation nuclei from combustion products, Warm, moist air over low, flatland areas on clear calm nights. Large areas of low ceilings and fog B. when is an airplane most likely to be struck by lightning leave the area of precipitation, if able, or fly Lenticular Clouds. Sometimes lenticular clouds are epic and dominate the skies over Tehachapi. B. The waves or clouds downwind from the mountain are the mountain are the "standing wave" or "lee wave." Cap clouds, rotor clouds, and standing lenticular clouds may form if the air has enough moisture. cumulus wave clouds by a mountain. Heavy icing conditions. The clouds would be parallel to the mountains from The most intense turbulence is usually located at low-levels, leeward of the mountains in or near the rotor cloud, if present; Mountain waves may be denoted by mountain wave clouds - Cirrocumulus Standing Lenticular (CCSL) - Altocumulus Standing Lenticular (ACSL) - Rotor clouds (often associated with the most intense turbulence) 2. Lenticular Clouds Page 001. Lenticular clouds (Latin: Lenticularis lentil-shaped, from lenticula lentil) are stationary clouds that form mostly in the troposphere, typically in parallel alignment to the wind direction. forecasters have a daunting task to provide accurate weather reports for pilots. A foehn wall cloud may exist at the lee side of the mountains, however this is not a reliable indication of the presence of lee waves. But theyre actually the result of normal scientific processes that happen right here on Earth! A localized low-pressure system often builds on the leeward side of the mountain. Turbulence The suffix 'nimbus' used in naming clouds, means a Rain cloud The presence of standing lenticular altocumulus clouds is a good indication of? This process results in a slight drop in pressure on the downwind side of the mountain. C heavy icing conditions. 124 The presence of standing lenticular altocumulus clouds is a good indication of. However, these waves can be present beyond the clouds, and may exist even when no Lenticulars form as part of atmospheric waves generated by air flowing over terrain obstacles such as mountains. A. turbulence at and below the cloud level. Its helpful to think of them as lens-ticular clouds to remember their characteristic lens shape. Standing lenticular clouds, in mountainous areas, indicate; Which weather condition can be expected when moist air flows from a relatively warm surface to a colder surface? Lenticular Clouds (lens shaped clouds) can form in the crest of the mountain waves if the air is moist. Crest of standing mountain waves may be marked by stationary, lens-shaped clouds known as: A. It makes sense that it would be a "rough ride". Like ocean waves, these waves of air bouncing over the mountains are anything but stable. A. a heat exchange . Known as Altocumulus Standing Lenticular (ACSL) or Altocumulus Standing Lenticularis clouds, they are associated with waves in the atmosphere that develop when relatively stable, fast moving air is forced up and over a topographic barrier that is oriented more or less perpendicular to the direction from which the upper-level wind is blowing. In order for mountain waves to form, they require a stable layer to exist above the ridge lines. Lenticular, or lee wave, clouds form downwind of an obstacle in the path of a strong air current. They are often comparable in appearance to a lens or saucer. C. Turbulence. 5. C) unstable air. Seeing these types of clouds along with the moon and sun provide a great glimpse of nature and all its power IKR . This occurs as the convection forces a wave or lenticular wave cloud into the more stable air above. They form in the updraft and dissipate in the downdraft, so they do not move as the wind blows through them. Pilots of powered aircraft tend to avoid flying near lenticular clouds because of the turbulence of the rotor systems that accompany them, but glider pilots actively seek them out. The precise location of the rising air mass is fairly easy to predict from the orientation of the clouds. Cirrus clouds. Wind blows most types of clouds across the sky, but lenticular clouds seem to stay in one place. They form in the updraft and dissipate in the downdraft, so they do not move as the wind blows through them. 123 Standing lenticular clouds, in mountainous areas, indicate An inversion. Standing lenticular clouds form in the crests of the mountain wave where the rising updraft of the wave has cooled and moisture has condensed. It makes sense that it would be a rough ride. 13) Crests of standing mountain waves may be marked by stationary, lens-shaped clouds known as: A. Cumulonimbus clouds. Pilots have come to accept all of these names for wave activity, regardless of position of the lenticular clouds. B) an inversion. 122.Which clouds have the greatest turbulence?

Large areas of low ceilings and fog B. Unstable air. By Karsten Shein Comm-Inst. Lenticular Clouds Lenticular clouds form due to the wind blowing across the top of a mountain at a pretty good speed. Lenticular clouds may contain winds of Unstable air. They are often called "wave clouds". This look very much like lenticular clouds. Standing lenticular clouds. Roll Clouds can also occur in the rotors below the waves if the air is moist. High-altitude cirrocumulus lenticularis clouds are the least seen of the three and take on a more polished, layer-like form. How are lenticular clouds formed? Saucer shaped lenticular cloud spotted over Patagonia, Argentina. which family of clouds is least likely to contribute to structural icing on an aircraft? Fair weather cumulus clouds often indicate Turbulence at and below the cloud level. C. Poor visibility. C. Clouds with extensive vertical development. Lenticular clouds can form at heights between 6,500 and 16,500 ft, and are called lenticular because of their lens shape. An inversion. C.

Standing lenticular clouds on the lee side of the Rocky Mountains indicate the presence of the Mountain Wave. Winds flowing through the narrow restriction of These clouds are also an indication of moderate to severe turbulence. A pileus or cap cloud, similar to a lenticular cloud, may form above the mountain or cumulus cloud generating the wave. Lenticular clouds form on the downwind side of mountains and are lens-shaped. Nimbostratus clouds. The presence of standing lenticular altocumulus clouds is a good indication of. Lenticular clouds, seen here in locations including Japan and Alaska, are saucer-shaped weather formations which gather over mountain peaks, and Jon Hammond. The greatest icing potential in cumulus clouds is found in the lower third. 4132 The presence of standing lenticular altocumulus clouds is a good indication of A- jet stream B- very strong turbulence C- heavy icing conditions Lenticular clouds are a visible sign of mountain waves in the air.

Crests of the standing waves may be marked by stationary, lens-shaped clouds known as standing lenticular clouds. The upward wind curls above the mountain, forming the lenticular cloud on the leeward side of the mountain crest. a. With this exception, the formation of ice attached to the external surface of an aircraft or to the surfaces within its engine air intakes, requires that liquid water drops impact the surface involved. Lenticular Clouds Page 001. The standing lenticular cloud is a stationary cloud that forms on top of mountains. These stunning lenticular clouds are often mistaken for an unidentified flying object (UFO) and for a good reason, as they seem to hover over It is possible that simple convection from mountain summits can also form wave clouds. Small areas of light snow or ice on the upper surface of the wing pose little or no threat to loss of lift. Lenticular Clouds. Nacreous clouds that form in the lower stratosphere sometimes have lenticular shapes. These rotor clouds appear to remain stationary, parallel the range, and stand a few miles leeward of the mountains. Standing lenticular clouds, in mountainous areas, indicate A) turbulence.

Crest of standing mountain waves may be marked by stationary, lens-shaped clouds known as: A. While Tehachapi is rightfully known as the Land of Four Seasons, it could also be known as the Land of Lenticulars, since the formation of these distinctive, sometimes amazing looking clouds is a common occurrence in the Tehachapi Mountains. The name Lenticular comes from the fact that this particular form of cloud looks like or at least is shaped similar to a lens. Heavy icing conditions. Lenticular and lee wave clouds form downwind of an obstacle in the path of a strong air current. present, lenticular clouds can form to give a visual indication of the wave action. Answer (1 of 2): When moist, stable air flows over a larger eddie, such as those caused by mountains, a series of large-scale standing waves form on the leeward side of the mountain.
