Continentality & Climate World Climate Patterns World Geo 3200/3202 Unit 2, Chpt 4 December 2010
Outcomes 2.5.1 Define the term temperature range. (k) 2.5.2 Analyze the relationship between range in temperature and distance from the ocean. (a) 2.5.5 Describe the relationship between seasonal level of precipitation and distance from the ocean. (k)
Temperature Range The difference between the highest and the lowest average monthly temperatures of a region. Regions with a large or high temperature range would experience extremes of temperature between hot summers & cold winters Regions with a small or low temperature range would have moderated temperatures with warm summers & cool winters
Continental vs. Maritime Climates We usually find that as the distance from the ocean increases the annual temperature range also increases. Continental climates experience greater extremes of temperature than coastal climates at the same latitude.
Continental vs. Maritime Climates Continental Climate: climate that develops away from the influence of the ocean accompanied by a large temperature range & low precipitation Maritime Climate: climate that is strongly influenced by the closeness to an ocean or other large water body accompanied by small temperature range & high precipitation
Continental Climates The plains region of Saskatchewan, for example, experience a continental climate. The winter temperatures are very cold. The summer temperatures are fairly hot. Large Temp Range..-40 to +40 It is interesting to note that summer temperatures in Central Labrador are often higher than summer temperatures in the island portion of the province.
Maritime Climates Coastal Newfoundland would experience a Maritime climate. Mild winter temperatures Warm but not hot summers High precipitation / Low temp range
Moderating Effect of Water Bodies of water have a moderating effect on land temps Oceans & large lakes heat up & cool down more slowly than the surrounding land In summer, water remains cooler than land surrounding it. Winds from the water cool the surrounding land
Moderating Effect of Water In winter, bodies of water retain their heat & are warmer than the surrounding land Winds blowing off the water warm the surrounding countryside Therefore, maritime locations near a large body of water, have cool summers & milder winters than continental locations far from the water body
You will need to understand climate graphs to analyze climate statistics. The left scale indicates the temperature and it is graphed as a line, blue is common. The right scale is for precipitation and is graphed as a bar graph, red is common.
Climate Graphs Used to help study the temperature & precipitation of a particular place Shows the cycle of temp & precip over a 12 month period Bar graph & line graph
Climate graph Features Precipitation Temperature Months Title Labels
Climate Graphs Bar Graph – On a climate graph, bars are used to show the total amount of precipitation over the course of any given month Precipitation is indicated by mm (millimetres)
