What would be the influence on the weather conditions when in mid-win...
The correct answer is option 'A' - 1 and 2.
When a feeble high pressure develops over the northwestern part of India in mid-winter, it has certain influences on the weather conditions. Let's examine each option in detail:
1. High and dry winds would blow outward from this high-pressure area:
When a high-pressure system forms, the air sinks and moves outward from the center. In this case, the feeble high pressure in the northwestern part of India would lead to the movement of air away from this area. These winds would be high and dry, meaning they would be devoid of moisture. As a result, the region would experience dry and cool winds blowing outward from the high-pressure zone.
2. The Northern plain would become cold:
As the high-pressure system develops over the northwestern part of India, it would lead to the intrusion of cold air from higher latitudes. This cold air mass would move southwards, affecting the northern plain of India. The cold air would cause a decrease in temperature, making the region colder.
Therefore, options 1 and 2 are correct as they describe the influences of the feeble high pressure on the weather conditions in mid-winter.
On the other hand, options 3 and 4 are incorrect:
3. Scorching winds (locally called loo) would blow during the daytime:
Scorching winds, locally known as "loo," are associated with high temperatures and are commonly experienced during the summer months, especially in northwestern India. However, in mid-winter, the presence of a feeble high pressure would lead to the movement of cool winds, not scorching winds. Hence, option 3 is incorrect.
4. There would be torrential rains brought by thunderstorms:
A feeble high pressure system is typically associated with stable atmospheric conditions, which are not conducive to the formation of thunderstorms or torrential rains. Instead, high-pressure systems generally bring clear skies and dry weather. Therefore, option 4 is also incorrect.
To summarize, when a feeble high pressure develops over the northwestern part of India in mid-winter, it would result in the outward movement of high and dry winds from this area and cause the northern plain to become colder.
