clouds with vertical growth
cumulus
cumulonimbus
special clouds
mammatus
lenticular
fog
contrails
most common of the high clouds. composed of ice and are thin, wispy clouds blown in high winds into long streamers.
cirrus clouds
when you see this cloud, it usually indicates that a change in the weather will occur within 24 hours
cirrus clouds
thin, sheetlike high clouds that often cover the entire sky. usually come 12-24 hours before a rain or snow storm
cirrostratus clouds
appear as small, rounded white puffs that appear in long rows. the small ripples in the cirrocumulus clouds sometime resemble the scales of a fish
cirrocumulus clouds
in tropical regions, they may indicate an approaching hurricane
cirrocumulus clouds
gray or blue-gray mid level clouds composed of ice crystals and water droplets. often form ahead of storms with continuous rain or snow
altostratus
mid level clouds that are made of water droplets and appear as gray puffy masses. if you see this on a warm sticky morning, be prepared to see thunderstorms late in the afternoon
altocumulus clouds
uniform grayish clouds that often cover the entire sky. they resemble fog that doesn’t reach the ground
stratus
low, puffy, and gray. most form in rows with blue sky visible in between them. rain rarely occurs with this kind of clouds however, they can turn into nimbostratus clouds
stratocumulus clouds
form a dark gray, wet looking cloudy layer associated with continuously falling rain or snow. they often produce precipitation that is usually light to moderate
nimbostratus clouds
white, puffy clouds that look like pieces of floating cotton. often called FAIR-WEATHER CLOUDS. the base is flat and the top of each cloud has rounded towers.
cumulus clouds
thunderstorm clouds. high winds can flatten the top into an anvil-like shape. associated with heavy rain
cumulonimbus clouds
low hanging bulges that droop from cumulonimbus clouds. usually associated with severe weather
mammatus
caused by a wave wind pattern created by the mountains. look like discs or flying saucers that form near mountains
lenticular clouds
cloud on the ground. composed of billion of tiny water droplets floating in the air.
fog
condensation trails left behind jet aircrafts
contrails
often associated with sever weather. it is thought to have something to do with having a high amount of liquid water drops and hail inside the clouds
green clouds
small, ragged clouds fragments that are usually found under an ambient cloud base. they form or have broken off from a larger clouds, and are generally sheared by strong winds, giving them a jagged appearance
fractus clouds
