Transcript of Clouds!!!

CLOUDS!!! By: Mikalynn Lowry
Whitney Gibson Fog..... Stratus Stratocumulus Nimbostratus Cumulonimbus Cumulus Altocumulus Fog usually floats around at ground level Stratus clouds are found below 6,000 ft Cumulus clouds are those white and puffy, cotton-like clouds. Cumulonimbus clouds range from 6,500 to 60,000 ft, making them the largest clouds Altocumulus clouds can be anywhere from 6,500 to 20,000 ft Fog forms when the difference between temperature and dew point is generally less than 4 degrees F Fog greatly reduces visibility at times.... Fog can be a hazard for
people who are driving,
and can cause them to
either speed up or slow
down while driving The term stratos is used to describe flat, hazy, featureless clouds. Stratos clouds are of very low altitude and vary in color.... from grey.... to white! Stratocumulus clouds are usually below 8,000 ft Stratocumulus clouds are the main type of cloud that can produce beautiful crepuscular rays..... Even though these types of clouds don't usually have precipitation, they are usually the leading front for thunderstorms. The base of a cumulus cloud is usually found below 6,500 ft, but the height can vary depending on the weather conditions. Glider pilots use cumulus as indicators of rising air drafts or thermals underneath of them. Nimbo comes from the word nimbus, which denotes precipitation This means that nimbostratus clouds are a sign of steady moderate to heavy precipitation Cumulonimbus clouds are the ones that are responsible for thunderstorms! A type of altocumulus cloud can oftentimes be mistaken for flying saucers, or UFOs for short! Towering altocumulus signifies a thunderstorm! If precipitation from an altostratus cloud increases enough, it could turn into a nimbostratus! Altostratus Altostratus clouds can be found between 6,500 and 20,000 ft You can usually see the sun shining trhough these clouds... Cirrus clouds range from 330 to 26,000 ft Cirrus Cirrus clouds vary in temperature, being anywhere from -4 degrees F to -22 degrees F. Thats freezing!!! Cirrus clouds are the reason we have tropical storms, or hurricanes! Cirrocumulus clouds are one of the main high-altitude clouds... Cirrocumulus They are found above 20,00 ft Cirrocumulus clouds usually only form in patches, but if they are formed with patches with cirrus or cirrostratus clouds, it usually means 8-10 hours of rain! Cirrostratus clouds are also found above 20,000 ft Cirrostratus Cirrostratus clouds are sometimes a signal of the beginning of a warm front coming in The term "hazy sunshine" refers to haze or light mist, usually from the milkey look of the sky when a cirrostratus cloud is present Lenticular clouds have a lenses type shape, hence the name lenticular. Lenticular They usually form between 20,000 to 40,000 ft Most pilots avoid these clouds because of the turbulence of the rotor systems that accompany the clouds Glider pilots, however, seek them out; the wave lift from the clouds enables gliders to soar to incredible heights. Contrails aren't naturally forming clouds; they are artificial clouds that form behind jets Contrails These clouds usually can be found above 16,500 ft Distrails are the opposite of a contrail; when a plane passes through a cloud, it can clear a path, which creates a distrail. Contrails have been researched to show that the temperature was about 1.8 degrees F higher than with contrails in the sky; the research was performed after 9/11 A single lobe of mammatus can last 10 minutes, but a whole cluster can last from 15 minutues to a few hours. Mammatus Mammatus clouds are probably some of the rarest clouds... Mammatus clouds often extend from under cumulonimbus, but they can also extend from altocumulus, altostratus, stratocumulus, cirrus, and volcanic ash clouds. These clouds are usually made up of ice, and due to their ominous appearance, are usually indicators of a severe thunderstorm. Nimbostratus clouds are found below 10,000 ft These clouds can also cause very heavy rain and flash floods!
