1. Continentality & Climate
Understand how continentality affects climate
Ch. 4 P
Continental
Coastal

2. Define the term temperature Range
Temperature range = the difference between the highest and the lowest average monthly temperatures of a region.
Large or high temperature range = extremes of temperature, hot summer cold winter.
Small or low temperature range = moderated temperature, warm summer, cool winter

3. Did You Know?
That Newfoundland’s annual temperature range is 20C. (Environment Canada)
In comparison, Winnipeg's is 38.9 and Vancouver's is 14.8.
Would you classify Newfoundland’s temperature range as extreme (high) or moderate (low)?

4. As distance from the ocean increases, summer temperatures are higher.
Analyze the relationship between range of temperature and distance to the ocean. P. 69
As distance from the ocean increases, summer temperatures are higher.
As distance from the ocean increases winter temperatures are lower
THE RESULT:
As distance from the ocean increases, annual temperature range increases (larger).
Continental climates experience greater extremes of temperature than coastal climates at the same latitude

5. Warm summers & cool winters
Hot summers & colder winters

6. Continentality…for real
The plains region of Saskatchewan, for example, experience a continental climate. The winter temperatures are very cold. The summer temperatures are fairly hot.
Coastal Newfoundland would experience a Maritime climate. The winter temperatures would be very mild. The summer temperatures would be warm but not hot.

7. Climate Graphs

8. Climate Graphs…cont’d
Where would this location be? (Northern Hemisphere, Southern Hemisphere or equator?)

9. Where?
Hemisphere?
Near water?
Seasons?
Summer
Winter
Dry
Wet
Temperatures?
Precipitation?
Dry
Wet

10. Explain the differences in these two climographs
Account for the seasonal changes in precipitation and temperature for a selected location
Explain the differences in these two climographs
Latitude?
Elevation?
Distance from ocean?
Type of rainfall?

11. Define “Monsoon” p. 70 From Arabic for seasonal wind
A sudden wet season in the tropics
Equator
Monsoons

12. Know why winter and summer. monsoons occur. P. 70-71
Know why winter and summer monsoons occur. P India’s Winter monsoon H L
Continental Asia cools (in comparison to….the ocean)
High atmospheric pressure results over the land
Wind blows southward towards the low over Indian ocean
Very little rain; dry wind blowing from the land

13. India’s Summer monsoonL H
Continental Asia heats up (in comparison to….the ocean)
Low atmospheric pressure results over the land
Wind blows northward towards the low over India
Heavy rains; moist wind blowing from warm Indian ocean

14. Distinguish between the terms weather & climate. P. 54
Climate = the average atmospheric conditions of a region.(longer term - ex. trend, monthly seasonal, yearly)
Weather = the state of the atmosphere at any one place or time. (ie. Short term - daily)
Both refer to temperature, rain fall, humidity etc.
Weather is short term Whereas climate is average over long time
