What are stratus clouds?

Stratus clouds are low -laid uniform clouds that cover the sky. Often they are a dull white to gray color and generally they are a kind of clouds that appear when people talk about a "cloudy day". Stratus clouds are generally not associated with poor weather, although they can be accompanied by drizzle and at higher altitudes may be the indicator that there is rain on the way. They are characterized by horizontal layers with an extremely even bottom. In Latin, "stratus" refers to a layer or blanket, and these terms are very suitable descriptions of classic stratus clouds. Sometimes clouds appear in a fragmented way, as in the case of stratus fractus.H rain and approaching storm. These clouds can also create a halo effect around the moon and stars when they are thinner and more vague. On a very turbid day, they can be completely covered by the sun, or it may occur in the form of blurred bright patches in the cloud coverage.

Sometimes the lighting conditions under the clouds of Stratus can be very interesting. These clouds tend to duplicate light and create a flattened look that filmmakers sometimes use to set a particular mood or tone. Many people consider them boring, because of their uniform gout, although they can be more interesting when they are fragmented under other clouds in the atmosphere. When stratus layers become extremely fragmented under higher clouds, it may be a warning that bad weather is on the way.

Like other clouds, the Stratus variety is formed when water vapor condenses. This is usually caused by the flam flow, the humid air that flows into the block of colder air. As a result, these clouds often appear on very muted days when the air has a high moisture content. In urban areas, low -lying clouds can also capture pollution, so people feel very dirty and sticky as a combined result of moisture and pollutants by the end of the day.
