Which one of the following is suitable for Koeppen’s “A” type of climate?
Explanation
According to Table 11.1 in the textbook, Koeppen's 'A' type (Tropical) climate is characterized by 'Average temperature of the coldest month is 18 C or higher.' This means that even the coldest month has an average temperature of at least 18°C, which implies that the mean monthly temperature of all the months is more than 18°C. Option A is incorrect because high rainfall in all months is a characteristic of the 'Af' subtype, not the defining feature of Group A. Option B is incorrect because 'more than freezing point' (above 0°C) is too broad and applies to many climate types including C and D. Option D is incorrect because it describes Group E (Cold Climates), not Group A.
Solution Steps
Step 1: Refer to Table 11.1 which defines Group A - Tropical climate characteristics.
Step 2: The table states: 'Average temperature of the coldest month is 18 C or higher.'
Step 3: If the coldest month is 18°C or higher, then all months must have temperatures at or above 18°C.
Step 4: Match this with option (C) which states 'Mean monthly temperature of all the months more than 18° C' - this is the correct interpretation.
