Study Notes
Weather Terminology and Concepts
- Air Pressure: The weight of the air pressing down on the Earth's surface, measured in pounds per square inch.
- Anticyclone: A high-pressure area characterized by descending air, typically leading to clear skies.
- Coriolis Effect: The phenomenon causing moving objects to curve due to the Earth’s rotation, impacting weather patterns.
- Cyclone: A low-pressure area that usually generates stormy weather.
Atmospheric Conditions
- Dew Point: The specific temperature at which air becomes saturated with moisture, resulting in condensation.
- Humidity: Refers to the amount of moisture present in the air, crucial for weather dynamics.
Meteorology Focus
- Meteorology: The scientific study focused on the atmosphere and weather systems, essential for understanding climate and forecasting.
- Precipitation: Any moisture that falls from clouds, including rain, snow, sleet, or hail.
Air Movement and Weather Patterns
- Jet Stream Flow (U.S.): Predominantly flows from west to east, influencing weather patterns across the country.
- Rising Warm Air: Creates low pressure areas, often leading to cloud formation and precipitation.
- Low Pressure Areas: Associated with stormy weather, rotate counterclockwise in the Northern Hemisphere.
Weather Fronts and Systems
- Front Severity: The greater the difference in weather conditions on either side of a front, the more severe the resulting weather.
- Stationary Front: A boundary between air masses where no significant movement occurs, leading to prolonged weather patterns.
Cloud Types and Weather Phenomena
- Cumulus and Cumulonimbus Clouds: Forms typically associated with cold fronts, indicating potential thunderstorms.
- Nimbostratus Clouds: Result from the gentle lifting of warm, moist air over cooler air, often leading to steady precipitation.
- Hail: Generally associated with thunderstorms, can cause significant damage.
Temperature and Atmospheric Layers
- Troposphere: The lowest layer of the atmosphere where nearly all weather events occur, contains the warmest air at the bottom.
- Boiling Point of Water: Occurs at 100 degrees Celsius under standard atmospheric conditions.
Air Mass Characteristics
- Air Mass: A large body of air with uniform temperature and humidity that remains in one area for an extended time.
- Relative Humidity: A comparison of the actual water vapor present in the air to the maximum it can hold, expressed as a percentage.
Severe Weather Systems
- Hurricanes and Typhoons: Large destructive cyclones that lose strength upon making landfall, leading to reduced impact.
- Changes in Barometric Pressure: Rapid shifts indicate significant weather changes, crucial for forecasting.
Atmospheric Stability and Air Movement
- Stable Air Indicators: Characterized by stratus clouds, cold air beneath warm air, and minimal vertical air movement, resulting in fog.
- Air Movement around an Anticyclone: Travels in a clockwise direction, contrasting the counterclockwise rotation of low-pressure systems.
