Key facts

1. The Bharat Forecast System (BharatFS) operates at a 6 km horizontal resolution.
2. This resolution surpasses its predecessor (GFS T1534 ~ 12km) and typical global operational models (9-14 km).
3. India is the only country running a global weather prediction model at a 6 km resolution for real-time weather prediction.
4. The system utilizes newly acquired supercomputing facilities: Arka (IITM-Pune) and Arunika (NCMRWF-Noida).
5. BharatFS aims to generate forecasts at the cluster of panchayats level and improve prediction of extreme weather events.
6. The increased resolution allows for capturing local weather features, enabling forecasts for specific panchayat/village clusters.
7. Localized forecasts assist farmers in crop planning, irrigation, and harvesting.
8. Water authorities can use these forecasts for better reservoir management during monsoons, reducing flood risk and improving yield resilience.
