Mission Mausam – India’s Advanced Weather Forecasting Initiative

Mission Mausam is a government programme launched by the Ministry of Earth Sciences in 2026. It aims to improve the accuracy, timeliness, and reliability of weather forecasts and early warning systems in India. The mission focuses on extreme weather events and climate services to enhance disaster preparedness and public safety.

Objectives and Implementation

Mission Mausam seeks to strengthen weather and climate prediction capabilities. It involves upgrading observation networks and enhancing numerical weather prediction models. The mission also expands high-performance computing (HPC) capacity and integrates Artificial Intelligence (AI) and Machine Learning (ML) for advanced forecasting. The India Meteorological Department (IMD), Indian Institute of Tropical Meteorology (IITM), and National Centre for Medium Range Weather Forecasting (NCMRWF) are key institutions implementing the mission. The phased implementation will continue until 2031.

Technological Enhancements

The mission upgrades Automatic Weather Stations (AWS), Automatic Rain Gauges (ARG), and Doppler Weather Radars across India. It establishes the Atmospheric Research Testbed (ART) in Madhya Pradesh to study monsoon convection and rainfall variability. AI and HPC systems enable better data assimilation from atmospheric, oceanic, and satellite sources. This leads to improved forecast accuracy and longer lead times for warnings on cyclones, floods, heatwaves, and other hazards.

Dissemination and Impact

Weather forecasts and warnings are shared via mobile apps like MAUSAM, MEGHDOOT, and DAMINI, along with SMS, TV, radio, and social media. The mission ensures coverage in all states and remote regions. Sector-specific advisories help farmers, fishermen, disaster managers, and the public prepare for weather changes. Improved forecasts assist crop planning, fishing operations, and disaster response, reducing risks and losses.

Significance for Various Sectors

In agriculture, better monsoon forecasts aid irrigation and crop protection. In fisheries, ocean advisories from the Indian National Centre for Ocean Information Services (INCOIS) improve safety and efficiency. Disaster management benefits from early warnings for extreme events, enabling timely evacuations. Overall, Mission Mausam aims to make India Weather Ready and Climate Smart.
