The meteorological services have significant impact on society in general. Public/private/government sectors demand for accurate prediction of weather and climate at various temporal and spatial scales is increasing due to possible impacts of global climate variability and change. Improved and reliable forecast of weather and climate requires high-resolution dynamical models (e.g. coupled ocean-atmosphere-biosphere-cryosphere models). Thus, a combined approach involving land, ocean and atmospheric processes hold the key to improve the forecasts of various temporal and spatial ranges. On the other hand, intensive monitoring of various weather systems through different platform based observing systems including satellites provide not only the necessary information about current weather systems, their effective assimilation in numerical models provide important guidance for accurate forecasts. ESSO has taken positive steps to implement comprehensive developmental programs in these lines involving all its constituent units.

The upgradation of weather forecasting capabilities to a sufficient level is one of the major priority programs launched during 11th Plan. It has four components, viz., atmospheric observation network; strengthening of computing facilities, data integration and product generation and dissemination of information. The activities related to computing, integration and product generation and dissemination have been completed. The argumentation of observational network is progressing. IMD now has a network of automatic weather stations, Doppler Weather Radars (DWR), state-of-the-art upper air systems etc. These observations are now being used to run its global and regional numerical prediction models on High Performance Computing Systems (HPC). It has improved forecasting capabilities for high impact weather events like cyclones, severe thunderstorm, heavy rainfall and floods in a significant manner.

Operational weather services have been greatly benefited by successful completion of the ‘Varsamana’ project, which has integrated observations, communication, analyses, forecasting and dissemination into a single system accessible across the country under the phase-I of the IMDs modernization plan.
