1. Constructing and Analyzing Climate Graphs

2. What is a Climate Graph? A climate graph combines a bar and line graph
It shows the average temperature and precipitation for each month in a given place

3. Creating Climate Graphs
The title of the area is shown at the top of the graph
The months of the year are listed along the bottom, with a single letter
Average monthly temperature is graphed on the left shown as a red line graph
Average monthly precipitation is graphed on the right shown as a series of blue bar graphs

4. Average Annual Temperature
Indicates a warm or cool climate
Ex. Toronto = 8.9ºC Yellowknife = -5.2ºC
To calculate average annual temperature
Add up the average temperature for each month and divide by 12

5. Temperature Range Indicates a Continental or Maritime climate
Continental = more than 25ºC
Maritime = less than 25ºC
To calculate temperature range
Find the number of degrees between the coldest temperature and the warmest temperature.
Warmest # - Coldest #

6. Total Precipitation Indicates a Continental or Maritime climate
Continental = less than 1000 mm
Maritime = more than 1000 mm
To calculate total precipitation
Add up the average precipitation for each month

7. Distribution of Precipitation
Three possibilities:
Summer max. = Continental
Winter max. = Maritime (West Coast)
Even. = Maritime (East Coast)
