Heat Wave and Disaster Management MCQ — 31 Practice Questions with Answers

Explanation

IMD states that it has followed the seamless forecast system since 2016 for maximum-temperature and heat-wave forecasts across seasonal, extended and short-to-medium ranges. The years 2014, 2018 and 2020 are near-miss years, but they are not the year stated for this system in the cited FAQ.

Explanation

The Assertion is true because IMD uses Red Alert when a severe heat wave persists for more than two days. The Reason is also true because Red Alert is also triggered when the total heat-wave or severe heat-wave days exceed six days. However, these are two separate Red Alert trigger conditions in the cited fact; the six-day threshold does not explain why a severe heat wave lasting more than two days qualifies.

Explanation

The correct pairing is impact-based heat-wave colour warnings with the National Disaster Management Authority, because IMD states that these warnings are issued jointly with NDMA. The Central Water Commission, National Health Authority, and Central Pollution Control Board are adjacent public institutions, but they are not named in this cited fact for issuing these heat-wave colour warnings with IMD.

Explanation

The Assertion is true because IMD's coastal-station rule requires a maximum-temperature departure of 4.5°C or more from normal and an actual maximum temperature of 37°C or more. The Reason is also true and explains the Assertion because the coastal rule is explicitly a combined condition, not a departure-only or actual-temperature-only threshold.

Explanation

The Assertion is true because the plan was issued by the District Disaster Management Authority, Dhaulpur. The Reason is also true because Sreenidhi B T, IAS, District Magistrate and Chairman DDMA Dholpur, introduced it. However, the introducer's designation does not by itself explain the issuing authority, so the causal link is not established. Answers that make either the Assertion or the Reason false conflict with the cited fact.
