Clouds
Visible masses of water droplets or ice crystals suspended in the atmosphere, formed through condensation and playing crucial roles in Earth's water cycle, climate regulation, and weather patterns.
Clouds
Clouds are fundamental atmospheric phenomena that form when water vapor condenses around tiny particles in the air. They serve as both visible markers of atmospheric conditions and critical components of Earth's water cycle.
Formation Process
Physical Mechanisms
- Requires cooling of water vapor to its dew point
- Depends on condensation nuclei (dust, salt, or smoke particles)
- Influenced by:
Types of Condensation
- Surface cooling
- Adiabatic cooling through uplift
- Frontal systems mixing
Classification
By Altitude
-
High-level clouds (above 20,000 ft)
- Cirrus
- Cirrostratus
- Cirrocumulus
-
Mid-level clouds (6,500-20,000 ft)
- Altostratus
- Altocumulus
-
Low-level clouds (below 6,500 ft)
- Stratus
- Stratocumulus
- Nimbostratus
By Formation
- Cumulus clouds (vertical development)
- Stratus clouds (horizontal layering)
- Cumulonimbus (thunderstorm clouds)
