The ministry of earth sciences (MoES) made operational its very high resolution (12 km) global deterministic model for generating weather forecasts in India. This will help India further improvement in Weather Prediction
The new model will replace the previous version which had a horizontal resolution of 25 km
The new model was very helpful in predicting and the intensity of recent cyclone Vardah and the cold wave over North India.
AS per ministry statement_ " Ministry of Earth science operational ensemble prediction system will also upgraded to 12 km from the horizontal resolution of 25 km. The EPS (Ensemble Prediction System) is adopted to overcome the problem of uncertainties in the forecasts and involves the generation of multiple forecasts using slightly varying initial conditions. Ensemble Prediction system also helps generate probabilistic forecasts and quantify the uncertainties”
MoES provides weather, climate and hydrological services to various users around the year. Both operational and research aspects for these services are implemented through IMD (India Meteorological Department) ,NCMRWF ( National Center for Medium Range Weather Forecasting), IITM (Indian Institute of Tropical Meteorology) and INCOIS (Indian National Centre for Ocean Information System)
