Study Notes
Orographic Precipitation
- Occurs when warm air rises over mountainous terrain and encounters cooler air.
- This results in condensation of moisture and precipitation on the windward side of the mountains.
- The leeward side, facing away from the wind, receives less precipitation due to the dry descending air.
Cyclonic Precipitation
- Caused by the convergence of air towards low-pressure areas.
- Air moves from high to low pressure, leading to rising air and subsequent condensation.
- Fronts are boundaries between air masses of different pressures.
- Warm fronts: Warm air advances over colder air, creating light precipitation over a large area
- Cold fronts: Cold air advances under warmer air, leading to heavy, short-duration precipitation over a smaller area
- Tornadoes and typhoons are often associated with cold fronts.
Clouds
- Formed when moist air rises and cools, causing water vapor to condense around dust particles.
- Classified based on shape and altitude:
- High-level clouds: Cirrus, cirrostratus, cirrocumulus (above 6 km, ice crystals)
- Mid-level clouds: Altostratus, altocumulus (2-6 km, water droplets and ice crystals)
- Low-level clouds: Stratus, stratocumulus, nimbostratus, cumulus, cumulonimbus (below 2 km, water droplets and ice crystals)
Precipitation
- Measured as the depth of rainfall that would accumulate on a flat surface.
- Different forms of precipitation:
- Rain: Liquid water
- Drizzle: Very fine rain
- Glaze: Freezing rain that freezes upon contact with surfaces
- Sleet: Rain that freezes before hitting the ground
- Hail: Frozen precipitation in the form of balls or lumps of ice
- Snow: Frozen precipitation in the form of crystalline flakes
Convective Precipitation
- Occurs due to vertical air movement (convection)
- Warm, humid air rises, cools, and condenses to form precipitation
- Often associated with summer thunderstorms.
- Warm surface heats air, causing it to rise and cool (convection)
- When the air cools to its condensation level, moisture condenses, forming clouds and precipitation.
Precipitation Measurement
- Rainfall is measured using rain gauges, which collect and measure the depth of rainfall.
