Study Notes

Weather and Climate Overview

This module is for 6th grade science.
Weather and climate are different things.
Weather is the current atmospheric conditions like temperature, rainfall, wind, and humidity.
Climate usually refers to the "average" weather patterns in an area over many years (typically 30 years).
An essential question to consider is how temperature and different heating of land and water affect weather and climate.

Essential Questions

How does temperature affect weather?
How do land and water differ in how they absorb and lose heat?
How does unequal heating of land and water lead to global wind systems?
What are the causes of weather events (tornadoes, hurricanes, thunderstorms)?
How can you relate the amount of moisture evaporation from the ocean to weather patterns and events?

Key Terms

Atmosphere: The mixture of gases that surround Earth.
Air pressure: The weight of air pressing down on an area.
Troposphere: The bottom layer of Earth's atmosphere; where most weather occurs.
Stratosphere: The layer above the troposphere; where ozone is present.
Mesosphere: The layer above the stratosphere, where meteors burn up.
Thermosphere: The outer most layer of the atmosphere.
Radiation: The transfer of energy by electromagnetic waves.
Conduction: The transfer of thermal energy through the collision of particles.
Convection: The transfer of thermal energy through the movement of liquids or gases.
Global warming: The rise in Earth's average temperature since the late 1800s and its predicted continuation.
Greenhouse effect: The process in which gases hold heat in the atmosphere.
Temperature: The average amount of energy of motion in the molecules of a substance; a measure of how hot or cold something is.
Global winds: Winds that continually blow over long distances from specific directions.
Local Winds: Winds that blow over shorter distances.
Coriolis effect: The way Earth's rotation makes winds in the Northern Hemisphere curve to the right and winds in the Southern Hemisphere curve to the left.
Water cycle: The continuous movement of water from Earth's surface to the atmosphere and back again as water vapor, precipitation (rain/snow), and ultimately evaporation.
Jet stream: A high speed, meandering air current.
Humidity: The amount of water vapor in the air.
Relative humidity: A comparison of the actual water vapor to the amount that could exist in the air at a given temperature and pressure.
Evaporation: The process of water changing from a liquid to a gaseous state.
Condensation: The process of water vapor changing from a gas to a liquid state.
Cumulus: Fluffy, rounded clouds often associated with fair weather.
Stratus: Flat, layered clouds.
Cirrus: Wispy, feathery clouds high in the atmosphere.
Barometer: An instrument used to measure air pressure.
Meteorologist: A scientist who studies the atmosphere and weather.
Precipitation: Any form of water that falls from the atmosphere to Earth's surface (e.g., rain, snow, sleet, hail).
Air mass: A large body of air with relatively uniform temperature and humidity properties.
Front: The boundary between two air masses with different characteristics.
Climate: The average, long-term weather conditions of a region.
Tornadoes: Rapidly swirling, violently rotating columns of air.
Hurricanes: Large, swirling tropical storms.
Heat: The transfer of thermal energy.

Atmospheric Layers and Heights

Troposphere: 0 - 18 km, bottom layer
Stratosphere: 18 – 50 km, contains ozone layer
Mesosphere: 50 - 80 km, meteors burn here
Thermosphere: 80 - 690+ km, Aurora Borealis occurs here.
Exosphere: 690+ km, outside layers of atmosphere
