weather and climate
100
  • a large body of air throughout which temperature and moisture are similar.

air mass

100

Day to day conditions of the atmosphere

weather

100
  • the average, general weather conditions over a large area.



What is climate

100
  • large-scale wind patterns that result from the uneven heating of Earth's surface by the sun.

Windbelts

100
  • Water _______________ the temperature.

    So you have cooler summers and warmer winters.

water

200
  • Air moves from areas of _____ ______ to areas of _________ ________.

areas of high pressure to areas of low pressure.

200

a measure of how much the molecules in the air are moving around

temperature

200

Five factors that affect climate

attitude, mountains, proximity to large bodies of water, elevation

200
  • There are three primary wind belts: 

 the trade winds, the westerlies, and the polar easterlies.

300

what does cP mean and the type of weather?

continental polar, Cold and dry

300

how much force air  applies to whatever  is below it

air pressure

300
  • angular distance of a location north or south of the equator and plays a significant role in determining climate patterns.

Lattitude

300
  • The _________ winds blow from the subtropical high-pressure belts toward the equator

trade

300

As latitude ____________, the average annual temperature _____________.

Increases, decreases

400

What do the following mean:

mP

mT

cT

maritime polar

maritime tropical

continental tropical

400

air moving from areas of high pressure to areas of low pressure

wind

400

receive more direct sunlight and experience warmer temperatures year-round

the equator

400
  •  the _______ blow from the subtropical high-pressure belts toward the poles.

westerlies

400
  • High latitudes

  • Cooler due to the low angle of sun – the rays are more spread out.

Drier because cooler air does not hold as much water

= North and South Pole

Why Learn About Air Masses?

  • helps us make sense of our daily weather.

  • Knowledge of air masses equips us to anticipate and prepare for extreme weather events. 


    • Farmers rely on weather patterns influenced by air masses. Knowing when to expect rain, frost, or heat is crucial for planning crops and ensuring food production.

500

the amount of water vapor in the air

humidity

500

receive less direct sunlight and have colder temperatures.

poles

500
  • The ________ _________ blow from the polar high-pressure belts toward the mid-latitudes.

polar easterlies

500
  • Low latitudes 

  • Hotter due to direct sunlight – more intense heat.
    • More humid due to rising air, which creates clouds.
