Approach:

  • Introduction: Significance of the Indian monsoon and its role in the Indian subcontinent’s climate and agriculture. Briefly outline the importance of Arctic sea ice in global climate systems.
  • Mechanisms of Influence:
    • Atmospheric Teleconnections: Changes in Arctic sea ice can affect atmospheric circulation patterns, such as the Jet Stream, which in turn influences the Indian monsoon.
    • Heat Distribution: Reduced Arctic sea ice leads to altered heat distribution and impacts the atmospheric pressure systems that drive monsoon winds.
    • Snow-Albedo Feedback: Melting Arctic ice affects the albedo effect and subsequent temperature changes in the Northern Hemisphere, influencing global weather patterns.
  • Impact on the Indian Monsoon: Impact on Onset, Duration, Intensity and Distribution
