(a) Plot a combined rainfall and temperature graph for Station X
(b) Calculate the (i) annual temperature range (ii) mean annual temperature for the station
(c) What climatic type does the station represent?
Explanation
(a) Plot a combined rainfall and temperature graph for station X
(b) Annual temperature range = Month with highest temperature minus month with lowest temperature Annual temperature range = 21°C – 12°C = 9°C
(ii) To derive the mean annual temperature add up all the temperatures for the year and divide by 12 Mean annual temperature
= 21 + 21 + 20 + 17 + 15 + 12 + 12 + 13 + 14 + 18 + 18 + 20
12
201 = 16.8°C

(c) The climatic type is Mediterranean climate
