Cloud Formation and Types

• A cloud is a visible condensation of water that is suspended in the air.

Cloud Formation

• Clouds form as warm air rises in the atmosphere and then cools down.
• Clouds are formed within specific layers of the atmosphere, primarily the troposphere.
• The troposphere is the lowest layer where weather phenomena occur.
• The sun heats water, which causes it to evaporate into the air.
• Warmer air rises, and cooler air sinks.
• As warmer air containing water vapor rises, it is cooled.
• Water vapor cools and condenses into water droplets in the air.
• As more air cools, more droplets form, creating different visible clouds.
• Different types of clouds form at different altitudes within the troposphere.
• Cloud formation depends on factors such as temperature, humidity, and air currents.

Cloud Types

• Cloud types are split into three groups according to the height of their base above mean sea level.
• Cloud types may also be categorized by a combination of characteristics.
• Alto means medium.
• Cirro means high.
• Cumulus means heaped or in a pile.
• Stratus means in a sheet or layer.
• Cirrus means thread-like, hairy, or curled.
• Nimbus means a rain bearer.
