| Cirrus clouds (meaning "curl")
are very high, thin, wispy clouds made of ice. At this high altitude,
the temperature is always below freezing. They may form feathery strands
called "mares tails" and often indicate an approaching warm
front. |
Stratus clouds (meaning "stretched
out")are unbroken sheets of gray clouds. They look like fog with
the base above the ground.They usually do not bring more than a drizzle
because there is no uplife movement in them. |
Cumulus clouds (meaning "heap") form when
warm air rises, carrying some moisture with it. They are puffy, white
and often bulge out at the top like cauliflower. They usually form
during the day when ground temperatures increase, and disappear at
night. |
