2Climate 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
3Learning about Climate Graphs Line graph for temperatureYou must be able to describe climate graphs.PrecipitationWhat is the yearly total?Is it wet, dry or seasonal?When is the highest and the lowest precipitation?TemperatureIs 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)?Graph shows verhojansk russia, in Siberia. Why don’t we use rainfall? Because sometimes its not rain, its snow.Bars show rainfall precipitation

8The average temperature The table below shows the climate data for Leeds in UK.JanFebMarAprMayJunJulAugSepOctNovDecAverage monthly Rainfall (mm)56414648535166Average monthly Temperature (°C)36711141613104The average temperaturein March is 6°CThe average rainfall inSeptember is 51 mmHow would you calculate the total annual rainfall?How would you calculate the average annual temperature?How would you calculate the temperature range?
9But how do you represent the data above in the form of a graph? JanFebMarAprMayJunJulAugSepOctNovDecAverage monthly Rainfall (mm)56414648535166Average monthly Temperature (°C)36711141613104, UKThe red line is the average temperatureThe blue bars show average rainfall
10Once you have drawn a climate graph you need to be able to interpret (read) the graph. The temperature peaks in July and August with an average of 16°C.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 maximum rainfall is 66 mm and the minimum is 41 mm – a range of 25 mm.The coldest months are January and February with an average monthly temperature of 3°C.The driest month is February when an average of 41 mm of rain falls.
11Adding the Growing Season Line The growing season lasts as long as the average temperature is above 6 CelsiusGrowing Season Line
129 Steps to a Perfect Climate Graph Mark the months on the X axis (bottom)Put a temperature scale on the leftPut a precipitation scale on the rightLabel units of measureAdd blue bars showing precipitationConnect temperatures with a red lineAdd a green line at 6°CShade the Growing Season (above green, below the red line)Add a title
