Study Notes
Cloud Formation and Types
- Clouds form when warm air rises, cools, and condenses around tiny particles (dust, pollen, sea salt).
- Condensation of water vapor creates liquid water droplets or ice crystals.
- Cloud types vary in altitude, shape, and characteristics.
Cloud Types and Characteristics
- Cirrus: High, thin, wispy, ice crystals, fair weather, possible weather change.
- Cumulus: Fluffy, white, flat bases, low altitude, can become storm clouds.
- Stratus: Gray, covers sky like a blanket, low altitude, light rain or drizzle.
- Nimbus: Dark, thick, heavy precipitation, often combined with other cloud types (e.g., cumulonimbus for thunderstorms).
Precipitation Types and Formation
- Relief Precipitation (Orographic): Moist air forced upward over mountains, cools and condenses on windward side, creates "rain shadow" on leeward side, common in mountainous regions.
- Frontal Precipitation: Warm air mass meets cold air mass, warm air rises, cools, condenses, forms clouds, leads to rain, common in temperate zones where fronts meet.
- Convectional Precipitation: Earth's surface heats air, warm air rises rapidly, cools, condenses, forms clouds, common in tropical areas, can lead to thunderstorms.
Types of Rainfall and Locations
- Relief Rainfall: Most common in mountainous regions, heavy on the windward slopes, little to no rain on the leeward side.
- Frontal Rainfall: Occurs where warm and cold fronts meet, can bring extended periods of steady rain, typical of temperate climates.
- Convectional Rainfall: Most common in tropical areas; short, intense bursts of rain, often associated with thunderstorms.
Weather Fronts
- A weather front is a boundary separating air masses with different temperatures and densities.
- Cold Front: Cold air mass pushes into warm air, often causing heavy rain or thunderstorms.
- Warm Front: Warm air mass moves over cold air, typically bringing light rain or drizzle.
- Stationary Front: Cold and warm air masses meet but don't move, leading to prolonged periods of cloudy, wet weather.
- Occluded Front: Occurs when a cold front catches up with and overtakes a warm front.
Cloud Heights and Types
- High-Level Clouds (above 5km): Only ice crystals, cirro- prefix, fair weather.
- Mid-Level Clouds (2km-5km): Mixture of water and ice crystals, alto- prefix, often produce rain or snow.
- Low-Level Clouds (below 2km): Primarily water droplets with some ice crystals, stratus, cumulus, and nimbostratus associated, nimbostratus most likely to have heavy rain.
- Cumulonimbus (low, mid, & high): Huge, towering, produce violent weather (hail, thunder, heavy rain), potentially tornadoes.
Types of Precipitation (Detailed)
- Frontal: Precipitation occurring at a weather front where the contact between warm and cold air masses causes the less dense, warmer air to rise, leading to condensation, cloud formation, and precipitation.
- Relief: Precipitation arising due to air being forced to rise over physical barriers like mountains, cooling and condensing as it rises leading to precipitation on the windward slopes.
- Convectional: Warm air rising due to lower density because of surface heating, cooling and condensation resulting in the formation of precipitation—typically thunderstorms.
