News Excerpt:
The Ministry of Agriculture & Farmers Welfare have initiated the weather information network and data system (WINDS) to generate long-term, hyperlocal weather data.
Weather forecasting in India:
- In India, the Indian Meteorology Department (IMD) is the principal government agency in all matters relating to meteorology.
- It specializes in the incredibly complex science of predicting weather patterns by observing, modeling and interpreting a multitude of variables.
- Currently, IMD operates around 800 automatic weather stations (AWS), 1,500 automatic rain gauges (ARG) and 37 Doppler weather radars (DWR).
- This is against the total requirements of more than 3,00,000 ground stations (AWS/ARG) and around 70 DWRs.
- In tropical countries like India, weather variability is inherently higher.
- Accurately predicting rain, cyclones, heatwaves and drought are critical to inform decision-making on disaster management.

About the WINDS system:
- The system will promote the data for wider agriculture and other sectors applications.
- It will help create a national-level database and assist in establishing the protocols required to access the country-wide data by the various public and private concerns.
- Under this programme, more than 200,000 ground stations (AWS and ARG) will be installed, which can help enhance weather data utilisation and thus improve weather predictions and decision-making.
Future prospects regarding weather forecasting systems in India:
- Through Make in India initiatives, many Indian companies have started manufacturing low-cost and highly reliable sensor-based air quality monitoring systems.
- These are also easy to install and have low maintenance costs.
- The IITs are helping as well, as they have started centres of excellence in this domain with a mission to establish a nationwide network of affordable air quality sensors.
- An integrated AI/ML-based model with data from the new air quality and weather sensors will be a major step forward in accurately predicting fog.
- It will help in timely decision-making around transportation and the health-related impacts of air pollution.
