Which Koppen climate subtype is identified by a short wet season and a long, severe dry period?
कोप्पेन (Köppen) जलवायु वर्गीकरण की कौन-सी उपप्रकार (Subtype) छोटी वर्षा ऋतु (Wet Season) तथा लंबी और तीव्र शुष्क ऋतु (Dry Season) से पहचानी जाती है?
Options / विकल्प
A. Af climate subtype (Af जलवायु उपप्रकार)
B. Aw climate subtype (Aw जलवायु उपप्रकार)
C. BSh climate subtype (BSh जलवायु उपप्रकार)
D. Am climate subtype (Am जलवायु उपप्रकार)
Correct Answer / सही उत्तर
✅ B. Aw climate subtype (Aw Climate Subtype)
Detailed Explanation / विस्तृत व्याख्या
Hindi
Aw जलवायु उपप्रकार को उष्णकटिबंधीय सवाना जलवायु (Tropical Savanna Climate) भी कहा जाता है।
इसकी मुख्य विशेषताएँ हैं:
- छोटी वर्षा ऋतु (Short Wet Season)
- लंबी और तीव्र शुष्क ऋतु (Long Dry Season)
- वर्ष भर उच्च तापमान
- घास के मैदान और विरल वृक्षों वाली वनस्पति (Savanna Vegetation)
इस जलवायु में वर्षा मुख्यतः ITCZ (Inter-Tropical Convergence Zone) के प्रभाव से होती है। शेष समय क्षेत्र शुष्क बना रहता है।
English
The Aw climate subtype is known as the Tropical Savanna Climate.
Its main characteristics are:
- Short wet season
- Long and severe dry season
- High temperatures throughout the year
- Savanna vegetation consisting of grasses and scattered trees
Rainfall mainly occurs when the Inter-Tropical Convergence Zone (ITCZ) moves over the region, while the rest of the year remains relatively dry.
Why Other Options Are Incorrect / अन्य विकल्प गलत क्यों हैं?
A. Af Climate (Tropical Rainforest)
❌ Incorrect
- No distinct dry season.
- Heavy rainfall throughout the year.
- Dense evergreen forests are common.
C. BSh Climate (Hot Semi-Arid)
❌ Incorrect
- Semi-arid steppe climate.
- Low rainfall overall.
- Not characterized by a distinct short wet season and long dry season like Aw.
D. Am Climate (Tropical Monsoon)
❌ Incorrect
- Receives very high annual rainfall.
- Has a short dry season, but rainfall is much greater than in Aw climate.
- Supports dense forest vegetation.

Köppen Climate Codes / कोप्पेन जलवायु संकेत
- A = Tropical Climate (उष्णकटिबंधीय जलवायु)
- f = No Dry Season (कोई शुष्क ऋतु नहीं)
- m = Monsoon Climate (मानसूनी जलवायु)
- w = Dry Winter (शुष्क शीत ऋतु)
- B = Dry Climate (शुष्क जलवायु)
- Sh = Hot Semi-Arid (गर्म अर्ध-शुष्क)
One-Liner / एक पंक्ति में
Aw (Tropical Savanna) climate is characterized by a short wet season and a long, severe dry season.
Aw (उष्णकटिबंधीय सवाना) जलवायु छोटी वर्षा ऋतु और लंबी, तीव्र शुष्क ऋतु के लिए जानी जाती है।
