(a) Draw a combined rainfall and temperature graph for the station
(b) Identify the climatic type represented by the data.
(c) Give four reasons for your answer in (b) above
Show the model answer
(a) Bar graph of monthly rainfall (left axis, mm) with a line graph of temperature (right axis, °C), months on the horizontal axis, title and scale shown
(b) Tropical continental (savanna/Sudan type) climate
(c) High temperatures all year (22-32°C, mean about 27°C); annual range about 10°C, larger than equatorial; single rainfall maximum in August (summer rain); long dry season (November-March) with almost no rain; total rainfall moderate (about 873 mm); highest temperature (32°C) just before the rains in April
A single peak of rain and a long dry season point to the savanna (tropical continental) type.
