According to the Köppen climatic classification, the letter code Cfa denotes
- A.Tropical wet climate
- B.Humid subtropical climate
- C.Tundra climate
- D.Tropical wet and dry climate
Correct answer
Explanation
The correct answer is B, Humid subtropical climate. In Köppen's code, C means a warm temperate climate, f means rain in all seasons with no dry season, and a means a hot summer.
Köppen grouped climates by temperature and rainfall, using capital letters A to E for the main groups and small letters for the rainfall season and summer heat. Cfa is found on the eastern sides of continents between about 25 and 40 degrees latitude, as in south-eastern USA, south-eastern China, southern Japan and eastern Australia. These areas have hot, humid summers, mild winters and rain spread over the year.
A is wrong because tropical wet climate is Af, with rain all year near the equator. C is wrong because tundra is ET, a polar climate with no warm month above 10 degrees Celsius. D is wrong because tropical wet and dry, or savanna, climate is Aw, with a dry winter.
Exam tip: Af is rainforest, Aw savanna, BWh hot desert, Cs Mediterranean, Cfa humid subtropical, ET tundra.
