What weather do cirrus clouds bring?
Cirrus clouds – thin, wispy clouds strewn across the sky in high winds. A few cirrus clouds may indicate fair weather, but increasing cover indicates a change of weather (an approaching warm front) will occur within 24 hours. These are the most abundant of all high-level clouds.
What do smooth clouds mean?

Why are cirrus clouds so thin?
Cirrus clouds are delicate, feathery clouds that are made mostly of ice crystals. Their wispy shape comes from wind currents which twist and spread the ice crystals into strands. Weather prediction: A change is on its way! Cirrostratus clouds are thin, white clouds that cover the whole sky like a veil.
Can clouds predict weather?
Here are some hints for predicting weather by reading clouds. Isolated, wispy, or very high clouds are an indication of fair weather. Crowded, dense, dark, and towering clouds indicate changing or worsening weather. If cloud color, shape, and size change, so will the weather.

At what height are cirrus clouds formed?
Ice clouds, also called cirrus clouds, are made up of ice crystals and start to form at altitudes of 5.5 km in temperate regions and of 6.5 km in tropical regions, making them the highest clouds in the troposphere.
How do clouds predict rain?
If it is rows of low, dark, lumpy clouds, then the weather is otherwise okay, but watch for further developments. If there is a low, dark, grey sheet, then it’s probably raining.

What is the most dangerous type of cloud Why?
Cumulonimbus (from Latin cumulus, “heaped” and nimbus, “rainstorm”) is a dense, towering vertical cloud, forming from water vapor carried by powerful upward air currents. These clouds are capable of producing lightning and other dangerous severe weather, such as tornadoes and hailstones.
How do you tell if a cloud is a rain cloud?
Do clouds have names?
Clouds are given different names based on their shape and their height in the sky. Some clouds are puffy like cotton while others are grey and uniform. Some clouds are near the ground, while others are near the top of the troposphere.
