Comprehensive Modernization Programme for IMD

for India Meteorological Department (IMD) covering (I) observation systems (ii) advanced data assimilation tools (iii) advanced communication and IT infrastructure (iv) high performance computing systems and (v) intensive/sophisticated training of IMD personnel to facilitate the implementation of advanced global/regional/-scale prediction models for improving the accuracy of weather forecasts in all temporal and spatial scales and for quick dissemination of weather forecast assessment / warnings to the users.

is given below:

FLOPS (10¹² Floating point Operations per Second) is now fully functional in Head Quarters (HQs) in scale models, for the purpose of forecast guidance in short (1-3 days) and experimental medium range (up to 10-days). These new range of numerical weather prediction (NWP) products are used for generating forecast assessment by various regional and state meteorological offices of IMD.

(9Kms grid scale ) that are being run at regional offices of IMD for their respective domains of country. To facilitate for the operation of high resolution -scale models at regional scale and to exchange forecast products across the state forecast offices in the country, high and computing servers are commissioned at 12 different locations viz. , , ,

frameworks that have undergone rigorous performance evaluation in operational R & D environment are being adopted subsequent to the commissioning of HPCS in IMD HQs for enhancing the weather forecasting capacities through:
