Cloudy

What does it mean when the weather is cloudy?

When the weather is described as "cloudy," it means that the sky is covered with clouds, and the amount of visible sunlight is reduced. Cloudy weather often occurs when there is a layer of clouds that block the direct view of the sun and can make the sky appear gray or overcast.

How are clouds formed?

Clouds are formed when water vapor in the air condenses into tiny water droplets or ice crystals. This process occurs when the air cools and reaches its dew point, causing the water vapor to change from an invisible gas to visible cloud particles.

Types of clouds:

• Cumulus clouds: These are puffy, white clouds often associated with fair weather.
• Stratus clouds: These are low, gray clouds that can cover the entire sky and are often associated with overcast, gloomy weather.
• Cirrus clouds: These are high, wispy clouds that are made of ice crystals and are often indicators of fair weather.

Effects of cloudy weather:

Cloudy weather can affect the temperature by trapping heat near the earth's surface, leading to milder temperatures. It can also reduce visibility and impact outdoor activities like stargazing and sunbathing.
