Stratus Clouds

Stratus clouds are low-lying clouds that form in a uniform layer. They often appear as a gray, featureless sheet that covers the entire sky, and they can bring light drizzle or snow.

Formation

Stratus clouds form when warm, moist air is forced to rise slowly, often as a result of a stable air mass or by the lifting of air over a broad area, such as a warm front. As the air rises, it cools and the water vapor in it condenses into tiny water droplets, forming the cloud layer.

Characteristics

Stratus clouds are typically uniform in appearance and can extend for large distances. They have a smooth, flat base and can block out the sun, creating overcast or cloudy conditions. Stratus clouds are associated with stable atmospheric conditions and are often seen in the absence of strong winds.

Weather Impact

Stratus clouds are generally associated with light precipitation, such as drizzle or light snow. They are also common in the aftermath of frontal passages and may linger for extended periods, creating overcast and gloomy conditions. However, they are less likely to produce severe weather compared to other cloud types.
