Q2. Explain the atmospheric conditions that lead to cold waves in India. Analyse the role of continental air masses in shaping winter anomalies across central and peninsular India. (10 M)
Difficulty Level: Medium
Reference: TH
Why the question Because recent cold-wave alerts and unusual winter anomalies across India have highlighted the influence of synoptic winter systems and continental air masses on India’s climatology. Key demand of the question The question requires explaining the atmospheric processes that generate cold waves in India and analysing how continental air masses influence winter temperature patterns across central and peninsular India. Structure of the answer: Introduction Brief context on India’s winter climatology and how large-scale synoptic conditions trigger cold waves. Body Atmospheric conditions for cold waves – Mention high-pressure formation, clear skies, dry air and cold northwesterlies. Role of continental air masses – Mention continentality, cT dominance, inland cooling and plateau-specific winter anomalies. Conclusion Forward-looking line on improving winter forecasting and minimising vulnerability in inland regions.
