2.5 Distance from the Oceans

Understand how distance from the oceans affects climate

2

2.5.1 Define Temperature RangeThe range between the highest and

the lowest average annual (monthly) temperatures of a region.

3

2.5.1 Define Temperature RangeLarge or high temperature range =

extremes of temperature, hot summer cold winter.

Small or low temperature range = moderated temperature, warm summer, cool winter

4

2.5.2 Relationship between range of temperature and distance from ocean As distance form the ocean

increases, annual temperature range increases.

Continental climates experience greater extremes of temperature than coastal climates at the same latitude

2.5.2 Relationship between range of temperature and distance from ocean

Warm summers & cool winters

Hot summers & cold winter

2.5.2 practiceCity Low & high temp. Dist. From ocean Km Temp. range

St. Johns -4 to +15 0

Regina -17 to +19 1350

Ottawa -11 to +21 700

Quebec city -11 to +20 350

Cities considered in this exercise are all between 44o & 50o

2.5.3 Define MonsoonFrom Arabic for seasonal windA sudden wet season followed by dry season

in the tropics

Monsoon Regions

2.5.4 Explain why winter and summer monsoons occur

Continental Asia cools

High atm. pressure results

Wind southward towards the low over Indian ocean

Very little rain; wind blowing over dry land

2.5.5 Relationship between amount of precipitation and distance from ocean

As distance from the ocean increases, seasonal precipitation decreases.

Continental climates experience lesser amounts of precipitation than coastal climates
