Question 5 of 5
5. Question
Consider the following statements.
- Western disturbances are periodic influxes of moisture-laden clouds from the Mediterranean that are common during winter and cause rain in northern India.
- The elevated temperatures and warmer waters in the Arctic Ocean reduces the intensity of Western disturbances over North-India.
Which of the above statements is/are incorrect?
Correct
Solution: b)
Western disturbances cause rain in northern India.
Western disturbances are periodic influxes of moisture-laden clouds from the Mediterranean that are common during winter.
Overall elevated temperatures are also contributing to warmer waters in the Arctic Ocean and drawing colder air from the poles with greater intensity.
This has added to the increased moisture, thereby seeding more intense western disturbance activity over north India.
