Study Notes

Types of Clouds

  • Cirrus Clouds: Light, feathery clouds composed of ice crystals; form at heights above 10,000 meters.
  • Cumulus Clouds: Big, puffy clouds formed from rising currents of warm air, characterized by flat bases.
  • Stratus Clouds: Sheetlike, layered clouds that typically form at low altitudes.

Cloud Formation

  • Clouds form through the process of condensation in the atmosphere.
  • Many tiny water droplets and ice crystals form around dust and other particles suspended in the air.
  • A cloud's shape is influenced by its method of formation.

Types of Fog

  • Fog is classified as a cloud that forms near the ground, typically in valleys, over rivers, and lakes.
  • Cooling ground temperature at night reduces the air temperature above, leading to condensation and fog formation.
  • Cool air moving over warm water can also contribute to fog development.

Cumulonimbus Clouds

  • Cumulonimbus clouds are an advanced type of cumulus cloud often linked with thunderstorms.
  • Updrafts can elevate these clouds to heights exceeding that of Mt. Everest.
  • As clouds rise, the tops flatten against the tropopause, resembling an anvil, which indicates potential thunderstorms.

Key Comparisons

  • Cumulonimbus clouds share characteristics with cumulus clouds, including formation at great heights and anvil-like tops.
  • Thunderheads are another name for cumulonimbus clouds.

Key Locations of Fog

  • Fog can be observed in various environments like valleys, rivers, and lakes.

Summary of Cloud Components

  • Clouds consist of numerous tiny droplets of water and ice crystals.

Basic Facts

  • The three basic types of clouds: cirrus, cumulus, and stratus.
  • Cumulonimbus clouds can be large and puffy, alongside cumulus clouds.
