Continentality

1
Continentality Climate

• Understand how continentality affects climate
• Ch. 4 P. 69-73

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 Newfoundlands annual temperature range is
  20C. (Environment Canada)
• In comparison, Winnipeg's is 38.9 and Vancouver's
  is 14.8.
• Would you classify Newfoundlands temperature
  range as extreme (high) or moderate (low)?

4
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
Continentalityfor 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.

Climate Graphscontd
Where would this location be? (Northern
Hemisphere, Southern Hemisphere or equator?)

• Where?
• Hemisphere?
• Near water?

• Seasons?
• Summer
• Winter
• Dry
• Wet

Temperatures?

• Precipitation?
• Dry
• Wet

10
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

12
Know why winter and summer monsoons occur. P.
70-71 Indias 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
Indias Summer monsoon
L
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

• HOMEWORK/LAB
• Create scatter-graph p. 69 33
• Draw a line of best fit
• Statement describing relationship between
  distance from the ocean and temperature range
