What causes altocumulus undulatus?

What causes altocumulus undulatus?

They result from wind shear (an abrupt speed or directional shifting in the wind, acutely changing with height). Lines one might see indicate the direction of the shear. In the southern United States, these formations may be the result of tropical or subtropical system outflow in a northern direction.

What causes altostratus undulatus?

It is the way the winds vary with altitude that tends to cause these formations. When blowing at different speeds above and below the cloud layer, the wind can cause the cloud to bunch up into ridges, which curve, join and divide, like the lines on your finger.

What weather does altocumulus clouds bring?

Altocumulus clouds are associated with unstable weather conditions. If you see one of these during the morning, you should expect a thunderstorm in the afternoon. Yet, precipitation is not that common from these clouds, so you may be free of rain if you see an altocumulus cloud.

What do undulatus clouds mean?

Stratocumulus undulatus clouds are puffy, undulating clouds low in altitude. Undulatus clouds are a bit more difficult to pick out in stratiform clouds. Cirrostratus undulatus clouds can be described as thin, high-altitude sheets with subtle wave patterns.

Do altocumulus clouds produce rain?

Mostly found in settled weather, altocumulus clouds are usually composed of droplets, but may also contain ice crystals. Precipitation from these clouds is rare, but even if rain does fall it doesn’t reach the ground.

What weather does altostratus clouds bring?

What weather is associated with altostratus clouds? Altostratus clouds often form ahead of a warm or occluded front. As the front passes, the altostratus layer deepens and bulks out to become nimbostratus, which produces rain or snow. As a result, sighting it can usually indicate a change in the weather is on the way.

How are altocumulus clouds formed?

Altocumulus clouds can form in several ways, such as; Formation through the breakup of altostratus. The lifting of moist air pockets which are cooled by gentle turbulence. Mountainous terrain producing atmospheric waves from which clouds can form.

What level is altocumulus?

Altocumulus generally forms about 2,000 to 6,100 meters (6,600 to 20,000 ft) above ground level, a similar level to altostratus formations, and satellite photography has revealed that the two types of cloud can create formations that can stretch for thousands of square miles.

Are Undulatus Asperatus clouds rare?

Undulatus asperatus (or alternately, asperatus) is a rare, newly recognized cloud formation, that was proposed in 2009 as the first cloud formation added since cirrus intortus in 1951 to the International Cloud Atlas of the World Meteorological Organization.

What weather does a altostratus cloud bring?

What do altocumulus clouds look like?

Altocumulus clouds have several patchy white or gray layers, and seem to be made up of many small rows of fluffy ripples. They are lower than cirrus clouds, but still quite high. They are made of liquid water, but they don’t often produce rain.

What does a altocumulus cloud look like?

Are altocumulus clouds high or low?

Where can altocumulus clouds be found?

Altocumulus clouds are composed primarily of water droplets and are located between 6,500 and 20,000 feet (2,000 to 6,000 meters) above the ground.

What do Undulatus Asperatus clouds mean?

Those are undulatus asperatus (agitated or turbulent wave) clouds, a type of cloud that is starting to get consideration as a wholly new category. From what I can tell, they are formed when there’s rising air that creates wide-spread cloud cover, together with wind shear that blows across the rising air.

Are altocumulus clouds rare?

What weather is associated with altocumulus clouds? Mostly found in settled weather, altocumulus clouds are usually composed of droplets, but may also contain ice crystals. Precipitation from these clouds is rare, but even if rain does fall it doesn’t reach the ground.
