Study Notes
Key Terms
- Atmosphere: The layer of gases surrounding the Earth.
- Air pressure: The force exerted by the air.
- Troposphere: The lowest layer of the atmosphere, where weather occurs.
- Stratosphere: The layer above the troposphere, containing the ozone layer.
- Mesosphere: The layer above the stratosphere, where meteors burn up.
- Thermosphere: The upper layer of the atmosphere, known for its high temperature.
- Radiation: The transfer of energy through electromagnetic waves.
- Conduction: The transfer of energy through direct contact.
- Thermal energy: Heat energy.
- Convection: The transfer of energy through the movement of fluids (liquids or gases).
- Global warming: The increase in Earth's average temperature.
- Greenhouse effect: The natural process where gases trap heat in the atmosphere.
- Temperature: A measure of the average kinetic energy of the particles in a substance.
- Global winds: Large-scale winds that consistently blow in one direction over a large area.
- Local winds: Winds that change direction more frequently, often influenced by local factors.
- Coriolis effect: The effect of Earth's rotation on the direction of winds.
- Water cycle: The continuous movement of water between the Earth's surface and the atmosphere.
- Jet stream: A high-altitude, fast-flowing air current.
- Humidity: A measure of the amount of water vapor in the air.
- Relative humidity: The amount of water vapor in the air relative to the maximum amount the air can hold at that temperature.
- Evaporation: The process of a liquid changing to a gas.
- Condensation: The process of a gas changing to a liquid.
- Cumulus: Puffy clouds.
- Stratus: Layered clouds.
- Cirrus: Wispy clouds.
- Barometer: A tool used to measure atmospheric pressure.
- Meteorologist: A scientist who studies weather.
- Precipitation: Any form of water that falls from the atmosphere to the ground (rain, snow, sleet, hail).
- Air mass: A large body of air with relatively uniform temperature and humidity.
- Front: The boundary between two different air masses.
- Climate: The average weather conditions in a region over a long period.
- Anemometer: A tool to measure wind speed.
- Thunderstorm: A storm with thunder and lightning.
- Tornado: A violently rotating column of air extending from a thunderstorm to the ground.
- Hurricane: A severe tropical cyclone with high winds and heavy rainfall.
Atmospheric Layers
- Layers of the atmosphere are differentiated by temperature changes, and composition.
Weather and Climate
- Weather - Short-term atmospheric conditions
- Climate - Long-term average conditions over decades or more.
Factors Affecting Climate
- Distance from the sea - proximity to ocean bodies, moderates temperature.
- Ocean currents - redistribute heat around the globe.
- Prevailing winds - directional air flow affects regional humidity and temperature.
- Landform shape - mountains and valleys affect local weather patterns.
- El Niño - climate pattern affecting weather globally.
Winds
- Winds are air moving from high-pressure areas to low-pressure areas.
- Convection currents in the atmosphere drive wind patterns.
- Earth's rotation causes the Coriolis Effect.
Clouds
- Clouds form from condensation of water vapor.
- Different types of clouds are based on height and appearance, and are further classified
- Air movement affects cloud shape.
Air Masses and Fronts
- Air masses are large volumes of relatively uniform air.
- Fronts are boundaries between air masses and are associated with weather changes.
Precipitation
- Different types of precipitation exist (rain, snow, sleet, hail).
- Each precipitation type has special properties and forms.
- Precipitation is influenced by the interaction of air masses and weather patterns.
Severe Weather
- Thunderstorms, tornadoes, hurricanes, and snowstorms are examples of severe weather.
Measuring Weather
- Tools like a barometer, anemometer, and rain gauges are used to collect weather data.
Weather Patterns
Examples of weather patterns include thunderstorms, tornadoes, hurricanes etc.
