How much rain does Chennai receive in November?

Category: Tamil Nadu Gk

Hint: Consider the monsoon season and typical rainfall patterns in Chennai.

Correct Answer: B) 350 mm.

Exam Relevance: UPSC, SSC, Bank PO, State PSC

Difficulty: Easy

Explanations:

Chennai, located in the southeastern part of India, experiences a tropical wet and dry climate. The city is influenced by the northeast monsoon, which brings significant rainfall to the region. The northeast monsoon typically starts in October and continues through December, with November being one of the wettest months.

The average rainfall in Chennai during November is approximately 350 mm. This amount is a result of the monsoon winds that bring moisture from the Bay of Bengal, leading to heavy rainfall. The monsoon season is crucial for agriculture and water supply in the region, as it replenishes water bodies and supports crop growth.

It is important to note that while the average rainfall is around 350 mm, there can be variations from year to year. Some years may see higher rainfall due to stronger monsoon winds, while other years may experience lower rainfall due to weaker monsoon activity. However, the average provides a good indication of the typical rainfall pattern in Chennai during November.

Understanding the rainfall patterns in Chennai is essential for various purposes, including urban planning, water management, and agricultural planning. The monsoon season plays a significant role in the overall climate and ecosystem of the region, and knowledge of these patterns is crucial for effective resource management and disaster preparedness.

Option Analysis:
  • Option A: This option suggests 450 mm of rainfall, which is higher than the average. While Chennai does receive significant rainfall during the northeast monsoon, 450 mm is not the typical average for November.
  • Option B: This option is correct. The average rainfall in Chennai during November is approximately 350 mm, reflecting the peak of the northeast monsoon season.
  • Option C: This option suggests 270 mm of rainfall, which is lower than the average. While this amount could occur in some years, it does not represent the typical average for November.
  • Option D: This option suggests 100 mm of rainfall, which is significantly lower than the average. This amount is more typical of months outside the monsoon season and does not reflect the wet conditions in November.
