Climate Graphs
Learning Goal: I can construct, interpret, analyze, and
apply climate graph data to Canada’s regions and
human lifestyles.

ANALYZING CLIMATE GRAPHS
NAME OF FORMULA
Mean Annual
Temperature
(MAT)
Annual Temperature
Range (ATR)
FORMULA
Add monthly temperatures ÷ by 12
*Round answer to 1 decimal place
Take the highest (warmest) monthly temperature and −
(subtract) from it the lowest (coldest) monthly temperature.
*Remember 2 negatives make a positive!
For Example:
20.1°C - (-3.4°C) = 20.1 + 3.4 = 23.5°C
• if the number is larger than 25°C = Continental Climate
• if the number is smaller than 25C = Maritime Climate
Total Annual Precipitation Add (+) all monthly precipitation totals together.
• less than 1000mm = Continental Climate
(TAP)
• greater than 1000mm = Maritime Climate
