Climate graphs and their interpretation By the end of today’s lesson you will: – know how to draw a climate graph; – be able to read a climate table and graph
Learning about Climate Graphs You must be able to describe climate graphs. Precipitation What is the yearly total? Is it wet, dry or seasonal? When is the highest and the lowest precipitation? Temperature Is it generally hot, cold or mild? When is the lowest month and the highest? What is the range of temperature (difference between high and low)? Bars show rainfall precipitation Line graph for temperature

How would you calculate the average annual temperature? How would you calculate the temperature range? The table below shows the climate data for Leeds in UK.

, Once you have drawn a climate graph you need to be able to interpret (read) the graph. The maximum rainfall is 66 mm and the minimum is 41 mm – a range of 25 mm. The driest month is February when an average of 41 mm of rain falls. The wettest month is August when an average of 66 mm of rain falls The maximum temperature is 16°C and the minimum is 3°C – a range of 13°C. The coldest months are January and February with an average monthly temperature of 3°C. The temperature peaks in July and August with an average of 16°C.
Adding the Growing Season Line The growing season lasts as long as the average temperature is above 6 Celsius Growing Season Line
9 Steps to a Perfect Climate Graph 1. Mark the months on the X axis (bottom) 2. Put a temperature scale on the left 3. Put a precipitation scale on the right 4. Label units of measure 5. Add blue bars showing precipitation 6. Connect temperatures with a red line 7. Add a green line at 6°C 8. Shade the Growing Season (above green, below the red line) 9. Add a title
