According to Koeppen’s climatic scheme of India, which type of climate is denoted by Aw?

The correct answer is Tropical savanna.

Key Points

• In Koeppen’s climatic classification, Aw represents Tropical Savanna climate, characterized by distinct wet and dry seasons.
• This climate is prevalent in regions with high temperatures throughout the year, typically above 18°C, and marked by seasonal rainfall patterns.
• In India, the Aw climate is observed in areas such as parts of the Deccan Plateau, Madhya Pradesh, and the northern parts of the Western Ghats.
• Rainfall in these regions is heavily influenced by the southwest monsoon, resulting in a wet season during summer and a dry season in winter.
• Vegetation in Tropical Savanna climates includes grasslands with scattered trees, adapted to withstand periods of drought.

Additional Information

• Koeppen’s Climate Classification:
  • Developed by Wladimir Koeppen, it is one of the most widely used climate classification systems globally.
  • It categorizes climates based on temperature and precipitation patterns.
  • The system uses letter codes such as A (Tropical), B (Dry), C (Temperate), D (Cold), and E (Polar).
• Key Characteristics of Aw Climate:
  • Aw stands for Tropical Savanna Climate with winter dryness.
  • Rainfall occurs predominantly during the summer monsoon season.
  • Annual precipitation typically ranges between 750 mm to 1250 mm.
• Vegetation in Aw Climate:
  • Tropical savanna vegetation consists of grasses and sparse trees such as acacia and baobab.
  • Plants are adapted to survive long dry periods and occasional wildfires.
• Indian Climatic Zones:
  • India’s climate is diverse, ranging from Tropical (A) to Alpine (E).
  • Koeppen’s classification helps in understanding regional climatic patterns and their impact on agriculture and biodiversity.
