**Summary:**
On May 26, 2025, the Ministry of Earth Sciences (MoES) launched the Bharat Forecast System (BharatFS) for real-time weather forecasting. BharatFS aims to enhance the accuracy of extreme weather prediction and generate forecasts at the panchayat cluster level. The system operates at a 6 km horizontal resolution, utilizing a Triangular Cubic Octahedral (TCo) dynamical grid. This resolution surpasses the 12km resolution of its predecessor, GFS T1534, and is finer than typical global models from other operational centers (9-14 km resolution). BharatFS incorporates improved orography representation, filtering, and conservation properties. The increased resolution enables the generation of distinct forecasts every 6 km, facilitating the capture of local weather features relevant to clusters of panchayats/villages. These localized forecasts support farmers in crop planning, irrigation, and harvesting, and aid water authorities in reservoir management during monsoon season to mitigate flood risk and improve yield resilience. Dr. Jitendra Singh, Union Minister of State (Independent Charge) for Science and Technology, Earth Sciences, MoS PMO, MoS Personnel, Public Grievances Pensions, Department of Atomic Energy and Department of Space, provided this information in a written reply in the Rajya Sabha.

PARLIAMENT QUESTION: BHARAT FORECAST
SYSTEM
Posted On: 31 JUL 2025 5:16PM by PIB Delhi
The Ministry of Earth Sciences (MoES) officially launched the Bharat ForecastSystem (BharatFS) on 26 May
2025 for real-time weather forecasting. The key objectives of BharatFS's development were to enhance the
accuracy of extreme prediction and produce forecasts at the panchayat cluster level.
The BharatFS is based on the newly implemented Triangular Cubic Octahedral (TCo) dynamical grid that
enables the model to operate at 6 km horizontal resolution, surpassing its predecessor (GFS T1534 ~ 12km).
Typical global models by other operational centers in the world are having a horizontal resolution of
9–14 km. It has improved representation of orography, better filtering, and better conservation properties.
With the increase in horizontal resolution, BharatFS can generate distinct forecasts at every 6 km. The new
model supersedes its predecessor in terms of model configuration and has shown significant improvement in
prediction skill.
This forecast system runs at a resolution of 6 km, which is typically about the size of a cluster of
panchayats/villages. With the increase in horizontal resolution, BharatFS is capable of generating distinct
forecasts every 6 km. This allows the capturing of local weather features, thus enabling the forecasts to cater
to a cluster of panchayats/villages. Localized forecasts help farmers with crop planning, irrigation, and
harvesting. Additionally, water authorities can better manage reservoirs during monsoon, reducing flood risk
and improving yield resilience.
This information was given by Dr. Jitendra Singh, Union Minister of State (Independent Charge) for Science
and Technology, Earth Sciences, MoS PMO, MoS Personnel, Public Grievances & Pensions, Department of
Atomic Energy and Department of Space, in a written reply in the Rajya Sabha today.
