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.
