Q. Consider the following description:
1. Annual and daily range of temperatures is low.
2. Precipitation occurs throughout the year.
3. Precipitation varies between 50 cm-250 cm.
What is this type of climate?
(a) Equatorial climate
(b) China type climate
(c) Humid subtropical climate
(d) Marine West coast climate
Correct answer: (d) Marine West coast climate
Question from UPSC Prelims 2024 GS Paper
Explanation :
1. Low annual and daily temperature range
– This suggests a moderating influence, typically from a large water body
– Eliminates continental climates which have high temperature ranges
2. Precipitation throughout the year
– No dry season
– Consistent rainfall pattern
– Rules out climates with distinct wet and dry seasons
3. Precipitation between 50-250 cm
– Moderate to high rainfall
– Broader range typical of mid-latitude climates
Looking at the options:
– Equatorial climate: Has year-round rainfall but typically higher precipitation
– China type climate: Has distinct seasonal variations
– Humid subtropical climate: Has more seasonal variation
– Marine West coast climate: ✓
– Moderated by oceans (low temperature range)
– Year-round precipitation
– Precipitation range matches
– Found along western coasts of continents in middle latitudes
The answer is (d) Marine West coast climate, as it perfectly matches all three characteristics mentioned in the description.
