Climate/weather Flashcards
What is LOWERN
Latitude Ocean currents Winds and air masses Elevation Relief Near water
Why does precipitation occur
When air containing water vapour cools to the point where condensation is greater than the evaporation of the vapour.
Air cools when it rises
The type of precipitation that occurs is determined by
An areas location
Physical features
What are the three types of precipitation
Relief
Conventional
Cyclonic
Explain relief precipitation
Pressure on the air decreases, causing it to expand and cool causing condensation and precipitation
2.pressure on the air increases causing it to become compact, warmer and drier
Where is relief precipitation common in
The western cordillera
Explain conventional precipitation
Warm air rises
- condensation takes place
- condensation continues and the clouds develop vertically
What is conventional precipitation most common in
Summer
Locations such as the prairie provinces, Ontario and Quebec
Match the types of precipitation to the following
1: summer
2: winter
3: storm
1: relief
2: convectional
3: cyclonic
Explain cyclonic precipitation
Large low pressure system that forms when a warm air mass and a cold air mass collide.
