3202 / 3200 / 3260 Climate Graphs WORLD GEOGRAPHY 3202 / 3200 / 3260 Climate Graphs Mr. Oliver H. Penney

How to draw a climate graph By the end of today’s lesson you should:  know how to draw a climate graph.  be able to read a climate table and graph.

JanFebMarAprMayJunJulAugSepOctNovDec Average monthly Rainfall (mm) Average monthly Temperature (°C) The average temperature in March is 6°C The average rainfall in September is 51 mm How would you calculate the total annual rainfall? How would you calculate the average annual temperature? How would you calculate the temperature range? The table below shows the climate data for Leeds.

Climate Graphs  Each climate graph is made up of 2 major parts. –A line graph for temperature.  Always represented by a red line. –A bar graph for precipitation.  Always represented by blue bars.

Climate Graphs  Line Graphs. –Temperature is easier seen with a line graph than by statistics. –The horizontal axis is used to show the time period (months), and the vertical axis is used to show the temperature (degrees Celsius). –The first step is finding the average temperature for each month and then plotting it on the graph. –Once you have done this you can connect the dots with a flowing line.  You should not see the dots when you are finished.

Climate Graphs  Bar Graphs. –They are similar to a line graph and easy to interpret. –The horizontal axis shows the time period (months), and the vertical axis shows the precipitation quantities (mm). –Bars are joined together to show a continuity from one month to the next. –You need to have the average precipitation for each month to construct the bar graph.

Climate Graphs  It is when the temperature line graph and precipitation bar graph are put together that you get a climate graph.  From a climate graph you can determine: –Temperature and temperature ranges for a particular place. –Rainfall and the seasonal distributions of rain. –Approximate latitude and elevation. –Northern or southern hemisphere.  You can identify climate types by carefully looking at the temperatures, the temperature range, the rainfall amount and the pattern of rainfall.

Climate Graphs

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.

Northern or Southern Hemisphere? Latitude/Longitude = 49.1 o N; o W Average Annual Temperature ( o C) = 9.8 Annual Temperature Range ( o C) =16 Total Annual Precipitation (mm) =1048 Summer Precipitation (mm) = 277 Winter Precipitation (mm) = 771 Latitude/Longitude: o S N; o E Average Annual Temperature (C) = 26.5 o Annual Temperature Range (C) = 10 o Total Annual Precipitation (mm) = Summer Precipitation (mm) =500 Winter Precipitation (mm) = 36.2
