Unit 2: Patterns in Weather & Climate
WEATHER AND CLIMATEChapter 4
Temperature Range (Defined)• Temperature range is the difference between the
highest and the lowest average monthly temperatures of a region.
• High temperature range equals extremes of temperature, hence hot summers cold winters.
• Low temperature range equals moderate temperature, hence warm summers, cool winters.
Continentality
Continental vs. Maritime Climates • Continental climates experience extremes of
temperature. Summers are hot and dry, winters are very cold and dry.
• Maritime climate experience warm (not hot) and humid summers, and mild and humid winters.
• Continental climates experience greater extremes of temperature than coastal climates at the same latitude!
• As distance from the ocean increases, annual temperature range increases!
• For example, the plains region of Saskatchewan, experiences a continental climate. The winter temperatures are very cold and the summer temperatures are fairly hot.
• For example, summer temperatures in Central Labrador are often higher than summer temperatures in the island portion of the province.
• Coastal Newfoundland would experience a Maritime climate. The winter temperatures would be very mild. The summer temperatures would be warm but not hot.
Monsoon• From Arabic for 'seasonal wind';
India’s Winter Monsoon• Continental Asia cools • Wind blows southward towards the low over Indian
ocean (as a result of the higher atmospheric pressure); • Very little rain, or dry season results, because the wind
is blowing over dry land and does not pick up moisture.
Monsoons
India’s Summer monsoon• Continental Asia heats up & low atmospheric
pressure results; • Wind blows northward towards the low over
India; • Tremendous rains result because the wind is
blowing over the warm Indian Ocean.
