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 ✓ UPSC's answer
Why the answer is (d)
• The Marine West Coast (British type) climate lies on the western margins of continents between 40° and 60° latitude, under the influence of onshore westerlies and warm ocean currents.
• Its marks are exactly those listed: mild temperatures with a low annual and daily range because of the moderating sea, rain in all seasons, and totals that vary widely (about 50–250 cm) depending on exposure to the westerlies and relief — option (d).
• The equatorial climate has a low range but very heavy, convectional rain above 200 cm; the China-type and humid subtropical climates lie on eastern margins with hotter summers and a larger temperature range.
• Western Europe, British Columbia, southern Chile, Tasmania and New Zealand are examples.
• Hence option (d).
Why the other options are wrong
- (a) Equatorial climate
- Equatorial rainfall exceeds 200 cm and is convectional, not 50-250 cm.
- (b) China type climate
- China-type climate has hot summers and a larger temperature range.
- (c) Humid subtropical climate
- Humid subtropical climates lie on eastern margins with a greater temperature range.
