Which of the following statements relating to given weather phenomena in India is/are correct ?
1. When maximum temperature of a station reaches ≥40°C for plains and ≥30°C for hilly regions, it is considered heat wave
2. When minimum temperature of a station is ≤10°C for plains and ≤0°C for hilly regions, it is considered cold wave
Select the answer using the code given below :

According to the India Meteorological Department (IMD), specific temperature thresholds must be met to consider the occurrence of heat and cold waves. For a Heat Wave, the qualifying criteria is a maximum temperature of at least 40°C for plains and at least 30°C for hilly regions. Once this threshold is reached, a heat wave is declared if the departure from normal is 4.5°C to 6.4°C. Similarly, a Cold Wave is considered when the minimum temperature is 10°C or less for plains and 0°C or less for hilly regions. For plains, a cold wave is specifically declared if the departure from normal is 4.5°C to 6.4°C or if the actual minimum temperature reaches 4°C or less. Since both statements correctly state the qualifying temperature thresholds established by the IMD, both are correct.
