Stratus Clouds

Stratus clouds are low-level clouds that typically form in layers with a uniform gray color. They are often associated with overcast or foggy conditions. These clouds are composed of water droplets and are usually found below 6,500 feet (2,000 meters) in the atmosphere.

Formation of Stratus Clouds

Stratus clouds form when warm, moist air is forced to rise and cool, causing the water vapor in the air to condense into tiny water droplets. This process occurs when a mass of warm air rises over a cooler air mass, or when air is forced to rise over a barrier such as a mountain range. As the air rises and cools, the water vapor condenses to form the stratus cloud layer.

Characteristics of Stratus Clouds

• Low-level clouds
• Appear as a uniform gray layer covering the sky
• Can lead to overcast or foggy conditions
• Do not usually produce precipitation, but can result in drizzle or light rain
• Can be observed from the ground or from an airplane
