Study Notes

Weather Instruments

Thermometers measure air temperature.
Rain gauges collect and measure precipitation.
Air masses are large bodies of air with consistent temperature and humidity.

Fronts

Cold Front: Cold air mass colliding with a warm air mass can cause strong storms, thunderstorms, and snowstorms.
Warm Front: Warm air mass rising over cold air mass creates gray clouds and rain.
Stationary Front: Two air masses meet and remain stationary.

Weather Concepts

Weather: Atmospheric conditions at a specific time and place.
Atmosphere: Layers of air surrounding Earth.
Evaporation: Liquid water turning into gas.
Condensation: Water vapor turning into liquid.
Precipitation: Water falling from clouds as rain, snow, sleet, or hail.
Runoff: Precipitation flowing downhill on Earth's surface.
Weather Conditions: Temperature, wind, and air pressure.
Air Pressure: Weight of air pressing on Earth's surface.
Humidity: Amount of water vapor in the air.

Weather and Climate Study Guide

Key Concepts:
- Define and describe weather and climate.
- Identify high and low pressure, precipitation, fronts, and cloud types on maps.
- Understand the water cycle.
- Read and interpret climate graphs and weather forecasts.

Cloud Classification

Classified by height and shape.

Severe Storms

Conditions for severe storms:
- High moisture content.
- Unstable air.
- Large temperature differences.
- Solar energy.

Hurricane Development

5 conditions for hurricane formation:
- Counter-clockwise rotation of winds in the Northern Hemisphere.
- Wind speeds exceeding 74 mph.
- Hurricanes can be upgraded based on conditions meeting the requirements.
- The eye of the storm is calm.

Hurricane Naming Convention

Hurricanes are named alphabetically using alternating boy and girl names.
Names of hurricanes causing significant damage are retired.

Tornado Watches and Warnings

Tornado Watch: Favorable conditions for tornado formation.
Tornado Warning: Tornado has been spotted on the ground.
A funnel cloud is not considered a tornado without ground contact.
Thunderstorms are often caused by collisions between cold and warm air.

Meteorologist Predictions

Predictions help people:
- Choose appropriate clothing.
- Plan their day.
- Stay safe during storms.

Weather Symbol Descriptions

High: Fair weather
Low: Rainy
