India Meteorological Department (IMD) has developed new technology called ‘Impact Based Forecasting Approach’ to assess rise of water level in rivers and reservoirs by rain. It shows pre-event scenario will help state governments authorities to minutely monitor impact of rainfall and take real-time decisions. It will help to avoid disastrous situation similar to Kerala floods. It can generate scenario to help take decisions to release water or not from reservoirs after heavy downpour. It will be helpful for every state authority to take decision. This system can be run in pre-event scenario.
The heavy downpour which had ravaged Kerala in August 2018 had caused death of around 500 people and economic damages worth over Rs 40,000 crore. Excessive rainfall had led to floods in Kerala and was result of climate change. State Government had blamed IMD for lapses in its part for wrong rain forecast. IMD had forecasted estimated 98.5 mm rain in the state between 9 and 15 August, 2018 but Kerala received was 352.2 mm of rainfall resulting in severe flooding.
India Meteorological Department (IMD)
It is national meteorological service of the country and chief government agency dealing in everything related to meteorology, seismology and associated subjects. It was formed in 1875. It functions under Ministry of Earth Sciences. It is headquartered in New Delhi.
- Undertake meteorological observations and provide current information and forecasting information for most favorable operation of weather-dependent activities such as irrigation, agriculture, aviation, shipping etc.
- Offer warning against severe weather phenomenon such as tropical cyclones, norwesters, dust storms, heat waves, cold waves, heavy rains, heavy snow, etc.
- Provide met-related statistics needed for agriculture, industries, water resources management, oil exploration, and any other strategically important activities for the country.
- Engage in research in meteorology and allied subjects.
- Detect and locate earthquakes and evaluate of seismicity in various parts of the country for developmental projects.

Prime Minister Narendra Modi chaired Cabinet Committee of Economic Affairs (CCEA) has approved continuation of nine sub-schemes of umbrella scheme “Atmosphere & Climate Research-Modelling Observing Systems & Services (ACROSS)” during 2017-2020. The scheme aims at improving skill of weather and climate forecast through sustained observations, intensive Research & Development.
The scheme pertains to the atmospheric science programs of the Ministry of Earth Sciences (MoES). Its objective is to provide reliable weather and climate forecast for betterment of society. It also aims at improving skill of weather and climate forecast through sustained observations, intensive R & D. It consists of nine sub-programmes which are multi-disciplinary and multi institutional in nature and will be implemented in integrated manner. It seeks to addresses different aspects of weather and climate services, which includes warnings for cyclone, storm surges, heat waves, thunderstorms etc. Each of these aspects is incorporated as nine sub-schemes under umbrella scheme ACROSS and is implemented in integrated manners.
Benefits of Scheme
It will provide improved weather, climate and ocean forecast and services, thereby ensuring transfer of commensurate benefits to the various services. It will also provide a sizable number of scientific and technical staff along with requisite administrative support, thereby generating employment. It will generate employment opportunities to many people as large number of agencies like the Krishi Vigyana Kendras of ICAR, Universities and local municipalities are roped to ensure last-mile connectivity of the weather based services to the end –user.
Union Ministry of Earth Sciences has mandate to carry out R&D activities to develop and improve capability to forecast weather, climate and natural hazard related phenomena. Towards this direction, it has undertaken several initiatives to formulate specific schemes like weather and climate modelling, monsoon-research, climate change science & climate services etc. These schemes involve multi-institutes wherein each unit has designated role for accomplishing aforesaid tasks. As result, all these schemes with specific objectives and budget are implemented in an integrated manner and are put together under the umbrella scheme “ACROSS”.
