चर्चा कीजिए कि बंगाल की खाड़ी उष्णकटिबंध में चक्रवातों के प्रति अधिक प्रवण क्यों है। साथ ही, दक्षिण-पश्चिम मानसून के मौसम में उष्णकटिबंधीय चक्रवातों की आवृत्ति में कमी के कारणों की व्याख्या कीजिए। (उत्तर 150 शब्दों में दीजिए) / Discuss why the Bay of Bengal is more prone to cyclones than the Arabian Sea. Also, explain the reasons for the decrease in frequency of tropical cyclones during the Southwest monsoon season. (Answer in 150 words)

Main Body
Timing of cyclones:
Usually end of SW-wt monsoon, October, April in Bay of Bengal
Reasons for decrease in frequency in SW monsoon:
1. Increase in vertical shear.
2. Active movement of Bay of Bengal branch of monsoon.
Thus the A-B-C lounge faces acute water shortage that is incarcerated. Besides this, foray of countries to produce more lithium prevents value addition and more generation in these countries (lithium imported as a natural resource).
Way forward:
1. Sustainable extraction methods: move away from brine extraction.
2. Mining done to prevent as much damage. eg use of Environmental Impact Assessment.
Hence, despite its importance, lithium must be used in a way and produced such that benefits accrue equitably to those involved.
