Study Notes

Weather and Climate Module Overview

This module is for 6th-grade MS Science.
It covers weather and climate topics.
The Sicily Isles and Newfoundland are geographically different despite comparable latitude, with different temperature and climate patterns.
Heat transport by the Gulf Stream affects climate variation.
Climate is a term used to describe the average weather for an area. The National Weather Service uses thirty years of data, including temperature, precipitation, and other statistics, to determine average weather patterns for a given region.
Weather is the current state of the atmosphere concerning temperature, precipitation, wind, and humidity.

Essential Questions

How does temperature influence weather?
How does heat absorption differ between land and water?
The interaction between land and water surfaces creates global wind systems.
What causes weather events like tornadoes, hurricanes, and thunderstorms?
How can moisture evaporation influence weather patterns?

Key Terms

Atmosphere: Gaseous layer surrounding Earth.
Air Pressure: Weight of air pressing on area, decreasing with higher altitude.
Troposphere: Bottommost layer of atmosphere.
Stratosphere: Layer above troposphere with ozone layer.
Mesosphere: Layer above stratosphere where meteors burn.
Thermosphere: The outermost atmosphere layer.
Radiation: Energy transfer via electromagnetic waves.
Conduction: Energy transfer through molecular collisions.
Convection: Energy transfer through movement of fluids (liquids and gases).
Global Warming: Rising average global temperature and ocean temperatures, starting in the latter half of the 19th century.
Greenhouse effect: The process by which gases trap heat in Earth's atmosphere.
Greenhouse effect: The process by which gases trap heat in Earth's atmosphere.
Temperature: Average kinetic energy of molecules; a measure of how hot or cold something is.
Global Winds: Winds blowing persistently over long distances.
Local Winds: Winds blowing over short distances.
Coriolis Effect: Impact of Earth's rotation on wind direction (to the right in the Northern Hemisphere; to the left in the Southern Hemisphere).
Water Cycle: Water's natural sequence from vapor to precipitation and back to vapor.
Jet Stream: High-speed current of air in the atmosphere.
Humidity: Amount of water vapor in the air.
Relative Humidity: Ratio of actual water vapor to the maximum amount possible at a given temperature and pressure.
Evaporation: Process of liquid turning into a gas (water vapor).
Condensation: Process of gas turning into a liquid (water from vapor).

Cloud Types

Cumulus: Fluffy, rounded clouds (like cotton balls).
Stratus: Flat, layered clouds.
Cirrus: Wispy, feathery clouds made of ice crystals.
Nimbus: Dark, rain clouds.

High-, Mid-, and Low-Level Clouds

High-level clouds include cirrus and cirrostratus.
Mid-level clouds include altocumulus and altostratus.
Low-level clouds include nimbostratus and stratocumulus.
Clouds with vertical development are fair-weather cumulus and cumulonimbus.

Other Cloud Types

Cloud types include contrails, billow clouds, mammatus, orographic, or pileus clouds.

Air Masses and Fronts

Air mass: Large body of air with similar temperature, pressure, and humidity throughout.
Front: Border where two air masses collide.
Humidity: Amount of water vapor in the air; the amount of moisture in the air.

Types of Precipitation

Rain: Liquid water droplets.
Sleet: Mixture of ice and rain.
Freezing rain: Rain that freezes on contact with very cold surfaces.
Hail: Balls of ice formed in thunderstorms.
Snow: Ice crystals.

Weather Patterns & Events

Thunderstorms: Usually form where warm, humid air rises and collides with a cold front.
Tornadoes: Rapidly spinning funnel-shaped clouds.
Hurricanes: Tropical storms, distinguished by high winds, deriving energy from warm ocean waters.

Safety Rules

Thunderstorms: Get inside a safe structure, avoid metal objects; go to designated shelters inside schools, hospitals, etc.
Tornadoes: Seek underground shelter (basements if available), avoid windows.
Hurricanes: Evacuate or move to interior rooms of sturdy buildings, away from windows.
