1º - Unit 5 Climate graphs

Climate graphs
Climate graphs are a combination of a bar graph and a line graph.
Temperature is shown on a line graph, with the figures being shown on the right side of the graph.

Rainfall is shown by a bar graph, with the figures being shown down the left side of the graph.
Interpreting climate graphs
In the exam you may be asked to look at the information in a graph and describe the area's climate.
  1. Look for patterns in the temperature data:
    • Is the temperature the same all year round? If it is different, how many seasons does the location experience?
    • Which season is the warmest? Is it warm (10 - 20°C), hot (20 - 30°C) or very hot (above 30°C)?
    • Which season is the coolest? Is it mild (0 -10°C), cold (-10 - 0°C) or very cold (below -10°C)?
    • What is the range of temperature? (Subtract the minimum temperature from the maximum temperature).
  2. Look for patterns in the rainfall data
    • Does the rainfall occur all year round?
    • What is the pattern of the rainfall? Check which season(s) is/are drier or wetter than others.
    • What is the total annual rainfall? Add each month's total together to get the annual total.
    • Then put the rainfall and temperature information together - what does it tell you about this area?
3. Describe the patterns in temperature and rainfall, including how they relate to each other.
You now have a description of the climate.

Now look at the climate graph below. What can you deduce about the climate?
