Question

Q5. Consider the following statements:

1. La Nina — a weather condition that generally brings heavy rains to India.

2. According to IMD, a monsoon is normal when the total amount of rainfall in the country between June and September is within 10 per cent (plus or minus) of the average rain over a long period.

Which of the above statements are correct?

• A. a) 1 only
• B. b) 2 only
• C. c) Both 1 and 2
• D. d) None of the above

Answer 1

The correct option is C

c) Both 1 and 2

• Both the statements are correct
• For India, an El Niño is often a cause for concern because of its adverse impact on the south-west monsoon; this happened in 2009. A La Niña, on the other hand, is often beneficial for the monsoon, especially in the latter half.
• The Indian Meteorological Department calls a monsoon season normal when the total amount of rainfall in the country between June and September is within 10 per cent (plus or minus) of the average rain over a long period.
• ‘Deficit rainfall’ is when it drops below the margin of 10 per cent of the average. ‘Excess rainfall’ is when it exceeds the average by more than 10 per cent. For example, there could be intense rainfall in the Northeast and low rainfall in central India. The national average rainfall would reflect as normal.
