Behind this push is a harsh truth: erratic weather is quietly costing India 0.4% of its GDP every year; that’s ₹1.2 lakh crore annually; thanks to floods, heatwaves and landslides. Farmers, airlines, insurers, and even green energy firms are all feeling the pinch. Mission Mausam, launched in 2025 with just ₹2,000 crore, is now set to get a massive boost; because 24 hours’ warning can cut storm damage by 30%. That’s why experts want more radars, better computers, and smarter models. This isn’t just tech for tech’s sake; it’s infrastructure resilience disguised as a weather upgrade. And if it works? Millions of livelihoods could be saved; and billions in losses avoided.
