Waec Model Questions Vol1 2022 Geography Question 14

The following table shows the average monthly temperature (°C) and precipitation (mm) for a location. | Month | Temp (°C) | Precip (mm) | |-------|----------|-------------| | Jan | 28 | 5 | | Feb | 30 | 10 | | Mar | 32 | 20 | | Apr | 34 | 40 | | May | 33 | 80 | | Jun | 31 | 120 | | Jul | 29 | 150 | | Aug | 28 | 140 | | Sep | 27 | 80 | | Oct | 26 | 40 | | Nov | 27 | 15 | | Dec | 28 | 5 | (a) Calculate the annual mean temperature (to one decimal place). (b) Calculate the total annual precipitation (in mm). (c) Using the Köppen climate classification criteria, identify the climate type (choose from Af, Am, Aw, Cw, etc.). Köppen criteria (simplified): - If the average temperature of the coldest month > 18°C and the precipitation of the driest month > 60 mm → Af. - If the coldest month > 18°C, driest month between 30-60 mm and total annual precipitation > 1500 mm → Am. - If the coldest month > 18°C and the driest month < 30 mm → Aw. - Otherwise other categories apply.
