Govt launches new weather forecasting system

Posted by


The India Meteorological Department (IMD) has launched a new Ensemble Prediction Systems (EPS) to provide probabilistic weather forecasts up to the next 10 days.
According to an official from meteorological department, the new system is highly accurate and will have resolution of 12km. The system involves generation of multiple forecasts using slightly varying initial conditions. The 450-crore acquisition of eight petaflops high-power computing systems will help in generating newer forecasts which have a higher resolution instead of the 23km resolution that has been in use. The forecast related to the intensity of the weather will also be more accurate and colour coded.
The new system is the best available model after the one used in Europe. Accurate forecasts will help farmers prevent damage to crops and aid administration in taking preventive measures before the onset of harsh weather patterns. Ministry of Earth Sciences has adopted the ensemble forecasting system, which provides not one but a collection of weather patterns for specific locations.
Ensemble forecasting provides localised predictions of a 12 km resolution compared to 23 kilometers in the earlier system. The new model has been developed jointly by Indian Institute of Tropical Meteorology and National Centre for Medium-Range Weather Forecasting.
With this new model, India joins the US with a model that predicts with a 12 km resolution. Only the ‘European Center for Medium Range Weather Forecast’ has a, better, nine-kilometer resolution. Better forecasts lead to better management agriculture and water resources. It also helps promote tourism, solar and wind energy.
