Unformatted text preview: her Classifications
Other Several other classification systems exist for
climate. These include classification by:
– Bioclimates 7 Ecoregions
Ecoregions Another way to classify a climate zone. Ecoregions focus on
the ecology of a region. This classification looks at:
– Climate There are 867 global Ecoregions Complete classifications is done by:
– Zones – Provinces
8 Example of Classification
Ecozone 15 top of hierarchy subcontinental scale. Large and generalized ecological units characterized by interactive and adjusting abiotic and biotic factors. Ecoprovince 53 characterized by structural or surface forms, faunal realms, and vegetation, hydrology, soil, and macro climate. Ecoregion eg, Newfoundland ecoprovince (no. 6.4) is one of 6 ecoprovinces in Boreal Shield Ecozone.
characterized by regional factors, including climate, physiography, vegetation, soil, water, and fauna. 194 eg, Maritime Barrens ecoregion (no. 114) is one of 9 ecoregions in Newfoundland ecoprovince. Ecodistrict 1021 characterized by assemblages of relief, landforms, geology, soil, vegetation, water bodies and fauna. eg, the Jeddore Lake ecodistrict (no. 473) is one of 5 in Maritime Barrens ecoregion.

11 Bioclimate Profiles
Bioclimate Series of Graphs which describe only temperature and moisture
conditions for a location
conditions Describe climate conditions and predict possible changes over
next 40-80 years. Source: http://www.utoronto.ca/imap/ 12
Climatographs Provide a quantitative breakdown of temperature and precipitation Shows fluctuation seasonally 13
13 Constructing Climatographs
Constructing the letters along the bottom of the graphs identify the months of
the year starting with "J" for January plot the dot in the middle of the bar for all months then join with
a smooth curving line to indicate the temperature conditions
(the scale is given at the left in Celcius)
– Convention: when using colour this line is usually 'red'
Convention: twelve vertical bars which indicate the average monthly amount
of precipitation. Use the millimetre (mm) scale to the right to
measure the amountsmeasure
– Convention: when using colour the bars are usually coloured in 'blue' 14 Group Exercise
Group You are given mean temperature and precipitation data for the following seven Canadian cities: Vancouver, BC
Medicine Hat, AB Each of the above cities belongs to a different climate region in Canada.
Your task is as follows:
Your Using the temperature and precipitation data from Table 1, determine the Köppen climate region that the
data originates from.
data When you have completed the task, match the cities in the table to one of the 7 cities listed above and
create the climatograph for each of the cities.
create Explain the differences that you see among the 7 climate zones. 15 Classifying Climate BACKUP SLIDES
