Flashcards in Climate Deck (28):
1

Describe relief/orographic precipitation.

- Warm air rises up windward size of mountain
- Air CCFAR
- As air descends on leeward side of mountain, it is compressed and heated

2

What is chinock?

The warm, dry air that is associated with the Western Cordillera and the Interior Plains

3

Describe cyclonic/frontal precipitation

- Warm + cold air meets
- Warm air rises and CCFAR

4

Where does cyclonic precipitation occur?

Ontario, Quebec, Maritimes, Prairies

5

Where does relief precipitation occur?

Western Cordillera. Interior Plains

6

Where does convectional precipitation occur?

Interior Plains, South Ontario, Quebec

7

Describe convectional precipitation.

- Ground heated by sun
- Air above warm ground rises due to convection
- Air CCFAR

8

What is the length of growing season?

# of months when average temperature is 6 or more degrees Celsius

9

What is the length of snowing season?

# of months when average temperature is 0 or less degrees Celsius

10

What are the factors affecting climate?

Latitude, Ocean currents, Wind + air masses, Elevation, Relief, Nearness to water

11

Is the Labrador ocean current cold or warm?

Cold

12

Is the Mexican ocean current cold or warm?

Warm

13

Is the Alaskan ocean current cold or warm?

Warm

14

What is a jet stream?

West to east movement of air flowing at speeds of 200 km/h at an altitude of 8000-15 000 m

15

What is a polar front?

Stormy boundary between cold, dry polar air and warm, moist tropical

16

What is climate?

Patterns of weather which have occurred over a long period of time (seasons)

17

It is a ___________ climate if it rains more than 1000 mm each each year and has an average temperature of less than 25 degrees C.

Maritime

18

What is weather?

Day to day condition of the atmosphere (temperature, humidity, precipitation, wind speed, cloud cover, air pressure)

19

What is an air mass?

A large volume of air with the climate conditions of the area where it originates

20

What are prevailing winds?

Winds that are most commonly found in an area. In Canada, they are the Westerlies, which blow from west to east

21

What is condensation?

Process whereby water vapour is cooled and changes from an invisible gas to liquid water. Condensed water vapour is what forms clouds

22

What are the climate regions?

Taiga, Arctic, Boreal, Southeastern, Cordilleran, Atlantic, Pacific, Prairie

23

What is Canada's coldest climate region?

Arctic

24

The temperature and precipitation of ________ climate region varies due to differences in latitude and elevation

Cordilleran

25

The mountains of BC are responsible for the little amount of rain in __________ climate region

Prairie

26

_________ climate region experiences cold winters for at least 6 months each year

Taiga

27

_____ climate region receives the least amount of precipitation in Canada

Arctic

28

Clouds that are associated with thunder storms are known as ___________

cumulo-nimbus clouds
