Consider the following statements regarding the wind circulation during the hot weather season: 1. Winds are southwesterly on the west coast. 2. Winds blow from the north-west direction over North Bengal and Bihar during this season. 3. These winds are actually displaced equatorial westerlies. Which of the statements given above is/are correct?

The correct Answer is 1 and 3 only Explanation The question pertains to the characteristics of wind circulation patterns during the hot weather season in India, specifically focusing on the pre-monsoon period and the onset of the monsoon. Understanding the direction and origin of these winds is crucial for comprehending regional climatic phenomena. Statement-wise Analysis 1. Statement 1: Winds are southwesterly on the west coast. Correct. During the hot weather season, particularly as the monsoon approaches, the low-pressure conditions over the Indian subcontinent intensify. This draws winds from the Arabian Sea. These winds, influenced by the Coriolis effect, approach the west coast of India from a southwesterly direction. These are the initial branches of the southwest monsoon. 2. Statement 2: Winds blow from the north-west direction over North Bengal and Bihar during this season. Incorrect. During the hot weather season (pre-monsoon), North Bengal and Bihar experience local severe storms accompanied by strong winds, often referred to as 'Nor'westers' or Kal Baisakhi. These winds are typically associated with thunderstorms and originate from the northwest, but they are localized phenomena and not the predominant large-scale wind circulation pattern across the entire region for the season. The statement implies a general wind direction, which is not accurate for the entire hot weather season. The primary large-scale wind circulation during the hot weather season, especially towards its end, is the onset of the monsoon from the south/southeast over this region. 3. Statement 3: These winds are actually displaced equatorial westerlies. Correct. The southwest monsoon winds are essentially equatorial westerlies that are displaced northward across the Equator due to the northward migration of the Inter-Tropical Convergence Zone (ITCZ) during the hot weather season. After crossing the Equator, these winds are deflected to their right (eastward) by the Coriolis force, becoming southwesterly as they approach the Indian subcontinent. Key Takeaway The southwest monsoon winds, which dominate the hot weather season's later part, originate as equatorial westerlies displaced northward and approach the west coast from a southwesterly direction.

Explanation

The question pertains to the characteristics of wind circulation patterns during the hot weather season in India, specifically focusing on the pre-monsoon period and the onset of the monsoon. Understanding the direction and origin of these winds is crucial for comprehending regional climatic phenomena.

These winds, influenced by the Coriolis effect, approach the west coast of India from a southwesterly direction. These are the initial branches of the southwest monsoon.

After crossing the Equator, these winds are deflected to their right (eastward) by the Coriolis force, becoming southwesterly as they approach the Indian subcontinent.

Key Takeaway

The southwest monsoon winds, which dominate the hot weather season's later part, originate as equatorial westerlies displaced northward and approach the west coast from a southwesterly direction.
