In an unprecedented advancement in developing weather forecasting technologies in India, the Government of India introduced the Bharat Forecasting System (BFS) on May 26, 2025. BFS is the Brainchild of the Indian Institute of Tropical Meteorology (IITM) Pune University, and with the reinforcement of the supercomputer Arka, BFS offers hyperlocal weather predictions.

What is BFS?

On May 26, 2025, the union government under the minister of earth sciences, Jitendra Singh, announced the launching of BFS. BFS increases weather prediction capabilities for complex phenomena related to risks of disasters, agriculture, hydrology, and even public safety, which helps in better planning and optimisation of resources.

Key Features of the Bharat Forecasting System

Ultra-High Grid Resolution:
- 6 km x 6 km, improving from the previous 12 km resolution

- Enables precise district- and panchayat-level forecasts

Supercomputing Power: Arka
- Speed: 11.77 petaflops

- Storage: 33 petabytes

- Processing Time: Reduces forecast generation time from 10 hours (Pratyush system) to just 4 hours

Nowcasting Capability:

- Offers real-time forecasts up to 2 hours ahead

- Integrates data from 40 Doppler Weather Radars, with plans to scale up to 100

Global Benchmarking

India now leads the world in high-resolution weather forecasting, especially for tropical regions.

Coverage and Reach

- Effective across tropical zones (30°N to 30°S)

- Covers the entire Indian mainland (8.4°N to 37.6°N)

Development and Backing

Developed by IITM Pune scientists, including Parthasarathy Mukhopadhyay

Supported by the Ministry of Earth Sciences (MoES)

Enabled by the installation of Arka, India’s top-tier weather-focused supercomputer

Significance and Applications

Agriculture: Better crop planning and advisories

Disaster Management: Timely warnings for cyclones, floods, and heatwaves

Urban Planning: Real-time climate risk insights

Water Management: Improved reservoir and irrigation planning

Public Safety: Faster alerts for extreme weather events

India’s BFS sets a new global benchmark, strengthening the country’s resilience against climate challenges while reinforcing self-reliance in weather technology.
