Eleamates Of Weather Concepts Flashcards
(25 cards)
Any form of water that falls from the atmosphere and reaches the ground as rain, sleet, snow, or hail
Precipitation
The amount of the Sun’s energy that reaches Earth
Insulation
Is a large region of air that has a similar temperature and humidity
Air Mass
A device for measuring air pressure
Barometer
Measures wind speed
Anemometer
Measures the heat of the air
Thermometer
Travel long distances around the world
Blows steadily over long distances in a predictable direction
Global Winds
The force put on a given area by the weight of the air above it.
Air pressure
The atmospheric layer of gases that is closet to Earth’s pressure
Troposphere
Marks the edge of a incoming air mass
Fronts
Is the amount of water vapor in the air
Humidity
What is this? 1. Moves clouds /precipitation 2. Makes sea and land breezes 3. Makes global and local winds 4. Wind speed affects how temperature feels on our skin ( Wind chill) And 5. Caused by pressure systems
Winds
A measurement of the average energy of particles in a object.
Temperature
Is the height above Earth’s sea level
Altitude
This wind flows from east to west at altitudes above 12 kilometers
Jet stream
What is this?
- Dives all weather on earth
- Heats land and water
- Heats earth unevenly because earth is a sphere
Sun
- The closer it is to the equator the hotter it is
- The farther away you are to the equator the colder it is
- Imaginary lines drawn around the earth
What is it?
Latitude
Is a area where oxygen and other gases, clouds, and weather are.
Atmosphere
A map that shows the weather in a specific point in time
Weather maps
Tools used to find what the weather might be at a certain time
Weather Instruments
- These winds don’t travel far
2. Some types of these winds are land breeze, valley breeze, and mountain breeze
Local winds
Dense
Cold front
Has cool dry air and brings cooler, dry, and clear weather
High air pressure
Has warm, humid air and forms clouds with stormy weather and precipitation
Low air pressure
