How Do Stratus Clouds Form?

What season do stratus clouds form?
Where do stratus clouds form in the atmosphere?
Stratus clouds are the lowest type found in the troposphere they are often found at ground level as fog or mist.
How are cirrus stratus clouds formed?
The formation of stratus clouds occurs when a sheet of cool air passes under a sheet of moist warm air. At the layer where these two sheets meet the warm upper air is cooled to condensation and forms a stratus cloud. The cloud will extend as far as the overlap between the sheets of air.
What type of weather does a stratus cloud produce?
Stratus clouds have flat layers and uniform bases with no visible clumps or lumps. They produce light precipitation in terms of drizzle and snow. They accompany foggy weather conditions. Stratus clouds can last for about 6 to 12 hours in the atmosphere.

What is an interesting fact about stratus clouds?
Stratus clouds are low altitude gray clouds that make a flat base. The name comes from the Latin word stratus which means to “stretch” or “extend.” You can see stratus clouds as thick cloud blankets near the sea. They are sometimes called “high fogs”.

Why do clouds turn GREY before it rains?
It is the thickness or height of clouds that makes them look gray. … The tiny water droplets and ice crystals in clouds are just the right size to scatter all colors of light compared with the smaller molecules of air that scatter blue light most effectively.
