Most of the Bihar comes under which of the following climate type?
Detailed Explanation:
Bihar experiences a Subtropical Monsoon climate characterized by three distinct seasons: hot summers (March–June), monsoon rains (June–September), and cool winters (November–February).
The state receives average annual rainfall of 1000–1200 mm primarily from the South-West monsoon, supporting cultivation of rice, wheat, and pulses across the Indo-Gangetic plains.
In which type of climatic region do Uttar Pradesh and Bihar fall as per Koppen's classification scheme?
Detailed Explanation:
Uttar Pradesh and Bihar fall under the Cwg climate type in Köppen's classification scheme.
Cwg denotes tropical wet and dry climate (savanna type) with dry winters (less than 60 mm rainfall in driest month), a hot summer, and the hottest month occurring before the summer solstice (typically May-June before monsoon).
Towards the end of summer, there are pre-monsoon showers which are a common phenomenon in Kerala and coastal areas of Karnataka. Locally, they are known as
Detailed Explanation:
Mango showers are pre-monsoon rainfall events occurring in Kerala and coastal Karnataka during late summer (April-May), coinciding with mango ripening season.
Blossom showers (also called April/coffee showers) refer to the same phenomenon, named after coffee blossoms in Karnataka.
Norwesters (or Kal Baisakhi) are entirely different—violent thunderstorms in eastern India (West Bengal, Odisha) during pre-monsoon months.
Since the question asks about Kerala and coastal Karnataka specifically, Mango showers is the most accurate local term, making Option 1 correct.

Rajasthan receives very little rain because
Detailed Explanation:
Rajasthan's low rainfall is primarily due to the Aravalli Range's orientation—it runs parallel to the Arabian Sea monsoon winds, preventing orographic uplift.
The Bay of Bengal branch loses most moisture over the Gangetic plains before reaching Rajasthan. Without a perpendicular mountain barrier to force air upward, winds remain at low altitude and do not cool sufficiently to condense into rainfall.
Therefore, the absence of barriers to cause necessary uplift makes Option 3 the correct answer.
