Question

Find out the temperature of Ooty (2240m) when it is 35°C in Chennai (6.7m)

Answer 1

Given: Temperature in Chennai having elevation of 6.7 m = 35 degree celcius

Elevation of Ooty = 2240 m

To Find: Temperature of Ooty.

Solution: The temperature of Ooty can be found out by using Normal Lapse Rate (NLR). According to the Normal Lapse Rate, the temperature of the earth atmosphere decreases 6.5 degree celcius with every 1000 m altitude.

Altitude difference between Ooty and Chennai = 2240 - 6.7 = 2233.3 m = 2.2333 Km

Hence, the temperature drop will be 2.233 * 6.5 = 14.51 degree celcius.

Therefore, temperature at Ooty will be = 35 - 14.51 = 20.49 degree celcius.
