Meteorological Observational Network in the Country Augmented

Earth System Science deals with the Earth system’s five components—Atmosphere, Hydrosphere, Cryosphere, Lithosphere, and Biosphere, and their complex interactions. The Ministry of Earth Sciences (MoES) holistically addresses all the aspects relating the Earth System Science for providing weather, climate, ocean, coastal state, hydrological and seismological services. The services include forecasts, warnings and detection for various natural disasters like tropical cyclones, storm surge, floods, heatwaves, thunderstorm and lightning and earthquakes etc. MoES is also mandated to conduct ocean survey and exploration for living and non-living resources and explore all the three poles (Arctic, Antarctic and Himalayas). The services provided by MoES are effectively used by various agencies and state governments for saving human lives and minimising damages due to natural disasters.

The significant milestones accomplished in 2020, under the five major schemes are highlighted below:

1. Atmospheric and Climate Research-ModellingObserving Systems and Services (ACROSS)

Accurate and timely prediction of the tropical cyclones Amphan, Nisarga and Nivar by the India Meteorological Department (IMD), combined with fieldwork by disaster management agencies, has helped save thousands of precious lives. The track and intensity forecasts of tropical cyclones have improved considerably in the past few years. Errors in the 24-hour forecast in track prediction and the landfall have reduced from 141 km to 73 km, and from 99 km to 18 km, respectively between 2006 and 2020.

• Launched the Flash Flood Guidance Services was launched this year, the first of its kind for South Asian countries namely India, Bangladesh, Bhutan, Nepal and Sri Lanka.
• Augmented meteorological observational network in the country: Four significant developments to enhance India’s meteorological observational network were made by IMD. These are listed below:

1. Meteorological observatory ofLehwas upgraded to a full-fledged Meteorological Centre. It was inaugurated by the Minister of Earth Sciences on December 29, 2020.
2. Seventeen high wind speed recorders were installed at Visakhapatnam, Machilipatnam, Chennai, Goa, Cuddalore, Bhubaneswar, Kakinada, Puri, Ongole, Digha, Kavali, Haldia, Pamban, Gopalpur, Kanyakumari, Veraval, and Bhuj.
3. A countrywide network of 25 Global Navigation Satellite System (GNSS) stations forEarth and atmospheric studies was setup. These have been installed and commissioned to deriveintegrated precipitable water vapour.
4. The phase six of Winter Fog Experiment (WIFEX) is being conducted at IGI Airport, New Delhi and Hissarfrom November 2020 to March 2021.

Dedicated New Earth stations have been setup under MMDRPS Project, which has the capability to receive the data from INSAT-3D, INSAT-3DR and upcoming INSAT-3DS satellites. IMD has hosted Real-Time Analysis Product and Information Dissemination (RAPID) for visualisation and analysis tool for satellite data on a real-time basis.
• Started receiving and utilising many new observations in its global and regional atmospheric data assimilation system during this period at National Centre for Medium Range Weather Forecasting (NCMRWF), Noida.
