Cirrus clouds are seen at an altitude of about $10\ km$ or more.
These clouds are made up of minute icy crystals so they appear as white silver in sunlight and colored at sunset.
When Cirrus clouds are spread like scattered feather, they indicate good weather, but if these are arranged in regular belts it suggests bad weather or approaching cyclonic condition.
These clouds do not give any rain.
$2.$ Stratus Clouds:
These clouds are seen within an altitude of $10\ km$ from the surface.
There are layers in this cloud just as the layered salted biscuits.
Due to this peculiar appearance where the layers are seen over one another, these clouds are known as Stratus Clouds.
In the upper layers of the air, if the warm and cool air comes from opposite directions over each other, they form the shape of a stratus cloud.
These clouds forecast the atmospheric disturbances.
Low lying stratus clouds give slow drizzle, but the high altitude stratus clouds which are spread like a bed sheet in the sky do not give any rain.
