NEW DELHI: India on Monday operationalised its indigenously developed high-resolution numerical weather prediction model – Bharat Forecast System (BFS) – that will significantly improve forecast accuracy by enhancing spatial resolution from the existing 12km to 6km. It will be the world’s first model offering such high resolution for localised forecasts.Weather forecast will thus now be available at the village level instead of a cluster of 4-5 villages under the existing system, enabling every village in the country to access more precise and location-specific forecasts.The high-spatial resolution will make it possible for IMD to forecast weather events which may take place in a grid of 6km by 6km in the tropical region that falls between 30 South and 30 North latitudes. BFS developed by Indian Institute of Tropical Meteorology, Pune, will improve the accuracy of extreme rainfall prediction by 30% and enhance the forecast accuracy for rainfall in the ‘monsoon core zone’ (areas where farming operations mainly depend on seasonal rains) by 64%, using real-time modeling based on the ‘Triangular Cubic Octahedral Grid model’.
