Study Notes

Cloud Classification

  • Clouds are classified based on height and shape.
  • Four basic types of clouds based on shape:
    • Stratus: Featureless sheets of clouds.
    • Cumulus: Puffy, lumpy clouds.
    • Cirrus: Wispy, stringy clouds.
    • Nimbus: Low, gray rain clouds.

Cloud Heights

  • Four levels of cloud heights:
    • Cirro: Bases start above 6000 m.
    • Alto: Bases between 2000-6000 m.
    • Strato: Below 2000 m.
    • Nimbo: Low elevation, dark and water-saturated.

Types of Clouds by Height

  • Common cloud types include:
    • Cirrus
    • Cirrocumulus
    • Cirrostratus
    • Altocumulus
    • Altostratus
    • Cumulonimbus
    • Stratus
    • Cumulus

Cloud Nomenclature

  • Cloud names like cumulonimbus and cirrostratus describe their characteristics.
    • Cumulonimbus: Associated with thunderstorms, can reach nearly 15,000 m, linked to extreme weather (lightning, thunder).
    • Cirrostratus: Thin, sheetlike clouds that form ahead of storms.

Formation of Clouds

  • Clouds form when warm air rises and cools, leading to water vapor condensing into tiny droplets.

Factors Influencing Cloud Characteristics

  • Cloud shape and height vary with temperature, pressure, and atmospheric water vapor.

Characteristics of Specific Clouds

  • Stratus: Smooth sheets at low altitudes.
  • Cumulus: Puffy, often with flat bases.
  • Cirrus: High, thin, feathery clouds made of ice crystals.

Precipitation

  • Precipitation occurs when water droplets in clouds grow large enough to fall to Earth.
  • Types of precipitation (rain, snow, sleet, freezing rain) are determined by air temperature.

Characteristics of Wind and Air Movement

  • Wind is air movement in a specific direction, caused by temperature differences and atmospheric pressure.
  • Cooler air is denser and sinks, resulting in high pressure; warmer air expands, rises, and creates low pressure.

Humidity

  • Humidity measures the amount of water vapor in the air; warmer air holds more water vapor.
  • Relative humidity compares the current amount of water vapor in the air to the maximum it can hold at a specific temperature.

Dewpoint

  • Dewpoint is the temperature at which air is saturated and moisture condenses into liquid or forms ice crystals.
