Introduction to BFS
On May 26, 2025, India achieved a significant milestone in meteorology with the launch of the Bharat Forecasting System (BFS). Developed by the Indian Institute of Tropical Meteorology (IITM), Pune, BFS is powered by the state-of-the-art supercomputer Arka. This advanced system offers the world’s highest resolution weather forecasts, providing a 6 km x 6 km grid resolution, surpassing the previous 12 km models. The BFS aims to enhance the accuracy and localization of weather predictions across India.
Technological Advancements
The BFS operates on Arka, India’s most powerful supercomputing facility, boasting a processing capacity of 11.77 petaflops and a storage capacity of 33 petabytes. This enables rapid data processing, reducing forecast generation time from 10 hours to just 4 hours. The system’s nowcasting capability allows for precise forecasts up to two hours in advance, integrating data from 40 Doppler Weather Radar.
Geographic Coverage and Global Standing
The BFS covers the tropical regions between 30°N and 30°S latitudes, with a specific focus on the Indian mainland, which lies between 8.4°N and 37.6°N. This high-resolution system positions India at the forefront of global weather forecasting, surpassing the resolution of European, U.S., and UK models, which operate at 9–14 km resolution.
Applications and Impact
The BFS is set to revolutionize various sectors by providing highly localized weather forecasts. In agriculture, it will offer precise advisories for crop management and irrigation planning. Disaster management agencies will benefit from timely alerts for extreme weather events, enabling better preparedness and response. Additionally, BFS will support urban planning, water resource management, and public safety initiatives.
Strategic Significance
The launch of the BFS aligns with India’s broader vision of becoming self-reliant in meteorological sciences. By developing an indigenous high-resolution weather forecasting system, India reduces dependency on foreign models and enhances its capacity to address climate-related challenges. The BFS also contributes to the nation’s goals under ‘Mission Mausam,’ which aims to upgrade weather forecasting capabilities through advanced technologies and infrastructure development.
Why This News is Important
Enhancement of Forecast Accuracy
The BFS’s 6 km resolution marks a significant improvement over previous models, allowing for more precise predictions of localized weather phenomena. This advancement is crucial for sectors like agriculture, where accurate weather information is vital for planning and decision-making.
Empowerment of Disaster Management
With its nowcasting capabilities, BFS can provide timely alerts for extreme weather events, enabling disaster management agencies to take proactive measures. This can lead to reduced loss of life and property during natural disasters.
Support for Sustainable Development
Accurate weather forecasts are essential for sustainable development, particularly in sectors like water resource management and urban planning. The BFS will provide the necessary data to make informed decisions in these areas.
Strengthening National Security
Reliable weather information is critical for national security, especially for defense operations. The BFS will enhance the Indian Armed Forces’ ability to plan and execute operations effectively, considering weather conditions.
Contribution to Global Meteorological Community
By developing an indigenous high-resolution forecasting system, India contributes to the global meteorological community’s knowledge and capabilities. The BFS sets a benchmark for other nations to aspire to in weather forecasting.
Historical Context
Evolution of India’s Meteorological Capabilities
India’s journey in meteorology began with the establishment of the India Meteorological Department (IMD) in 1875. Over the decades, India has made significant strides in weather forecasting, from basic observational methods to the development of advanced numerical weather prediction models. The introduction of the BFS is a culmination of years of research and development in the field of meteorology.
‘Mission Mausam’ and Technological Advancements
The launch of the BFS is part of the broader ‘Mission Mausam,’ an initiative aimed at enhancing India’s weather forecasting capabilities. Launched by Prime Minister Narendra Modi, Mission Mausam focuses on upgrading weather surveillance technologies, implementing high-resolution atmospheric observations, and developing high-performance computing systems. The BFS aligns with these objectives by providing a state-of-the-art forecasting system developed indigenously.
