Wiki User 2017-02-07 02:06:38 Produced when a rotating column of air condenses, funnel clouds are the visible part of tornadoes that extend downward from the parent thunderstorm cloud. B. Cloud Formation. The rising air expands and cools until it reaches it's dewpoint temperature and then, if there are tiny specks of dust in the air to trigger the condensation, droplets will form and you'l have a cloud there. Even in the sky, we can see rare cloud formations and these sights keep us mesmerized, wondering how beautiful nature can be. Standing lenticular clouds are lens shaped clouds, hence their name. They form as air is lifted to saturation over the top of mountains. A long snake-like lenticular cloud above Lake Tahoe at sunset on May 11, 2018. Standing lenticular clouds form in the crests of the mountain wave where the rising updraft of the wave has cooled and moisture has condensed. One of the most feared and easily recognized storm clouds is the funnel cloud. This leads to a stationary cloud even though the air is steadily flowing. They usually form when a layer of air near the surface encounters a topographic barrier, gets pushed upward, and flows over it as a series of atmospheric gravity waves. Weather fronts, where two large masses of air collide at . As air flows around large surface features, wind velocity tends to increase, and in turn pressure and temperature decrease, causing a cloud to form. These clouds are a good indication of the presence of mountain waves but, if the air is dry, there may not be any cloud to see. As damp air flows over mountain peaks, the waves of air carve out a pocket on the downwind side, and if the front side of that downwind . Lenticular Clouds over Plymouth, NH Plymouth State University Meteorology Program Cloud Boutique The Plymouth State Meteorology Program has developed this web page to provide explanations of and access to detailed pictures of some basic cloud forms. Clouds which have extensive vertical dimensions are often classified as: These clouds appear most often in formations of orographic origin, the result of lee waves, in which case they remain nearly stationary with respect to the terrain (standing cloud), but they also occur in regions without marked orography. contrails. So, you need rising air and some sort . Lenticular, or lee wave, clouds form downwind of an obstacle in the path of a strong air current. The rising air expands and cools until it reaches it's dewpoint temperature and then, if there are tiny specks of dust in the air to trigger the condensation, droplets will form and you'l have a cloud there. You would most likely expect a rainshadow on the: east side of the Cascade Mountains in the . Creast of standing mountain waves may be marked by stationary, lens-shaped clouds known as . Lenticular clouds indicate waves in the air flow caused by strong winds blowing across the range. They are most likely to form when the direction they are travelling is at a right angle in comparison to the direction of the wind. According to meteorologists, lenticular clouds are formed when moisture driven by strong winds encounters a topographic barrier, such as a mountain, that forces it to condense into clouds. However, the most dramatic clouds are generated by the largest ranges, such as the Himalayas, Andes, and Rocky Mountains.

Which cloud type is most likely to produce a brief yet intense period of precipitation? If the temperature at the crest of the wave drops below the local dew point, moisture in the air may condense to f. This occurs when stable, moist air flows over a mountain, creating a series of oscillating waves. Standing lenticular clouds form in the crests of the mountain wave where the rising updraft of the wave has cooled and moisture has condensed. 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. The lens-shaped lenticular cloud appears over the ridge and to the lee of mountain ranges. Lenticular clouds. a. cumuloaltus b. stratus . In a deep conditionally unstable or absolutely unstable environment, one may expect clouds to develop with A type of arcus cloud, roll clouds are generally associated with the gust front of a thunderstorm.

POLAR LIGHT (AURORA) All types of clouds are formed by these processes, especially altocumulus, altostratus, cirrocumulus, stratocumulus, or stratus clouds. Like ocean waves, these waves of air bouncing over the mountains are anything but stable. Lenticular clouds are shaped like lenses or almonds or.flying saucers! Clouds also form when air is forced upward at areas of low pressure. Get solutions Get solutions Get solutions done loading Looking for the textbook? Lenticular clouds indicate great instability in that layer of the atmosphere, and form in areas of mountain waves. A - A warm, moist air mass on the windward side of mountains. These formations are frequently caused by wave motions in the atmosphere, and are frequently seen in mountains or hilly areas. Altocumulus Lenticularis can create cumulus clouds. Answer: Stable air flowing over a mountain. Question. Lenticular clouds form when air flows over a topographical feature such as a mountain. But remember, not until the funnel reaches the ground or "touches down" is it called a tornado. Moisture is forced out of the air into the form of a cloud as the air rises over the land feature and then returns back to the vapor form as the air descends down the other side. It makes sense that it would be a "rough ride". steam fog is more likely to form during the ____ and advection fog in early ____ condensation nuclei. Visibility is decreased when stratus clouds are present and fog is likely to form. All types of clouds are formed by these processes, especially altocumulus, altostratus, cirrocumulus, stratocumulus, or stratus clouds. An early sign that the conditions might be right to form afternoon thunderstorms! As the wind blows against the mountains, it is forced upward and moisture condenses, forming a cloud that . Advection fog is most likely to form in coastal areas, with warmer air moving over the cold ground causing fog to form. 5) Lenticular. Click to see full answer.

Mt. provides equal amounts of precipitation on both sides of a mountain range. A lenticular cloud is a good "forecast indicator" as tall mountains accentuate incoming high-level moisture well ahead of an approaching front. Smooth, lens-shaped . B - An air mass moving inland from the coast in winter. 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. In Homeric Greek . ". Smooth, lens-shaped . Altocumulus Lenticularis Clouds can form if stable, moist air collides with a large stationary object, such as a building or a mountain. 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. Cloud streets. The clouds dissipate in the downdrafts of the wave where the air has descended and warmed to the point where the moisture evaporates . A type of arcus cloud, roll clouds are generally associated with the gust front of a thunderstorm. environment, one may expect clouds to develop, but their vertical growth will be limited, and may observe: cumulus humilis (shallow cumulus) stratocumulus In an absolutely stable environment, no clouds will likely form. C. a light breeze blowing colder air out to sea . You're most likely to spot a lenticular cloud near hills or mountains. They need a certain air current to form, and just the right. Roll Clouds can also occur in the rotors below the waves if the air is moist. Cloud formations directly downwind or above large terrain features will be turbulent. Solutions for Chapter 6 Problem 18QR: (a) Why are lenticular clouds also called standing wave clouds? nacreous clouds.

Rainbow clouds tends to happen with altocumulus, cirrocumulus, lenticular and cirrus clouds. . Match the cloud type with the mechanisms or condition that most likely formed it. Wind blows most types of clouds across the sky, but lenticular clouds seem to stay in one place. The clouds dissipate in the downdrafts of the wave where the air has descended and warmed to the point where the moisture evaporates and is no longer visible. Winds meet at the center of the low pressure system and have nowhere to go but up. The funnel cloud is the visible portion of a tornado produced from clouds. The clouds form in the rising current on the upwind side of the wave crest and dissipate in the downward flow on the other side. Unlike arcus clouds, however, roll clouds have a very long, tube-like shape. In the Boulder, Colorado area, the obstacle is the Front Range of the Rocky Mountains, seen at the bottom of the picture.
