Clouds And Their Types  The types of clouds are based on what
they look like and how high are they in the sky. Based on this,
we have 4 major divisions. They are :  1. High level: They are
formed in altitudes more than 20,000 feet. Because the
temperatures are very cold at these high elevations, these
clouds are mainly composed of ice crystals. High level clouds
are further divided in to three main parts:   Cirrus
clouds: They are very weak and thin clouds that are blown away
by high winds. They usually mean that the day will have a
pleasant and fair weather. These clouds flow in the direction of
the winds at their altitudes.  cirrus cloud  Cirrostratus : They
are very thin sheets of clouds extending over large parts of the
sky. They are composed of ice crystals and are very difficult to
detect. They sometimes signal the beginning of a warm front.
These clouds do not show any precipitation.  cirrostratus cloud
Cirrocumulus: They look like small cotton puffs in the sky. They
are sometimes known as Mackerel cl
