The correct answer is II only.

Key Points

  • The retreating monsoon phase in India is characterized by winds that blow from the north and get deflected to come from the northeast.
  • This deflection of winds is primarily due to the Coriolis force, which acts on moving air masses due to the Earth's rotation.
  • The northeast monsoon winds are responsible for bringing rainfall to parts of South India, particularly the eastern coast, during the months of October to December.
  • Statement I is incorrect because the retreating monsoon winds come from the northeast, not from the northwest.
  • Understanding the direction and characteristics of these winds is crucial for agricultural planning and water resource management in the affected regions.

Additional Information

  • The Coriolis effect plays a significant role in the global wind patterns, influencing weather systems worldwide.
  • The retreating monsoon marks the transition from the rainy season to the dry season in many parts of India.
  • Understanding the dynamics of the monsoon system is essential for predicting weather patterns and planning for agriculture and water management in India.
