Answer & Explanation
Correct answer: (A) Tropical Savanna
According to Köppen’s climatic classification, Odisha experiences a Tropical Savanna climate (Aw). This classification is characterized by:
- Distinct wet and dry seasons – Odisha has a pronounced monsoon season (June-September) with heavy rainfall, followed by a dry winter period
- High temperatures year-round – Average temperatures remain above 18°C throughout the year
- Seasonal rainfall pattern – Most precipitation occurs during the southwest monsoon, with relatively dry conditions during winter months
- Annual rainfall typically 1000-1500mm – Concentrated mainly in the monsoon months
The coastal areas of Odisha may show some variation, but the dominant climate type across the state is tropical savanna. The hot, humid summers followed by a distinct dry season with moderate temperatures are characteristic features that align with the Aw classification in Köppen’s system.
