About Bharat Forecast System
- It is India’s first indigenously developed weather model.
- Developed by the Indian Institute of Tropical Meteorology (IITM), Pune.
- It is a deterministic model, meaning it provides a single-model-based output, unlike ensemble models which give multiple outputs.
- Key specifications:
- Spatial Resolution 6 km × 6 km — the highest resolution globally for a national model.
- Existing Model 12 km × 12 km — covers 144 sq km per forecast unit.
- Coverage– BFS can provide 6 km resolution forecasts for the tropical region that falls between 30 degrees South and 30 degrees North latitudes.
- The Indian mainland extends between 8.4 degrees North and 37.6 degrees North latitudes.
- Forecast Accuracy- Capable of predicting small-scale weather phenomena such as localized thunderstorms, cyclones, and extreme rainfall with much greater accuracy
- Spatial Resolution 6 km × 6 km — the highest resolution globally for a national model.
