Given below are two statements, one is labelled as Assertion (A) and other is labelled as Reason (R).
Assertion (A): Cyclonic conditions are formed in winters when the atmospheric pressure is high and the air temperature is low.
Reason (R): Winter rains lead to anticyclonic 5 conditions with low temperature over North India.
Select the correct answer using the options given below.

Correct option is C

Correct Answer: (C) (A) is false, but (R) is true.
Explanation
​Assertion (A): Cyclonic conditions are formed in winters when the atmospheric pressure is high and the air temperature is low.
This statement is false. Cyclonic conditions generally develop in low-pressure areas, where air moves inward and rises. In winter, high-pressure conditions usually prevail over northern India due to low temperatures, which actually leads to anticyclonic conditions rather than cyclonic ones. Therefore, cyclones are not formed because of high pressure and low temperature.

Reason (R): Winter rains lead to anticyclonic conditions with low temperature over North India.
This statement is true. During winter, northern India experiences low temperatures and relatively high atmospheric pressure, which leads to anticyclonic conditions. Winter rainfall in North India is mainly caused by western disturbances, which bring moisture and precipitation to the region.

Since Assertion (A) is incorrect but Reason (R) is correct, the correct option is:
(C) (A) is false, but (R) is true.
​Information Booster
Cyclone: Associated with low-pressure systems where air converges and rises.
Anticyclone: Associated with high-pressure systems where air descends and diverges.
Western Disturbances: Mediterranean-origin weather systems that cause winter rainfall in North-Western India
