ISRO inaugurates S–Band Polarimetry Doppler Weather Radar at Sriharikota spaceport

Indian Space Research Organisation (ISRO) has inaugurated S–Band Polarimetry Doppler Weather Radar (DWR) at Satish Dhawan Space Centre in Sriharikota spaceport, Andhra Pradesh. It will be used for observation of weather system up to range of 500 km and also for early warning of severe weather events.

Doppler Weather Radar (DWR)

The radar has been indigenously developed by Bharat Electronics Ltd (BEL), Bengaluru under ToT (Training of Trainers) from ISRO. It is the seventh radar of such type manufactured in the country under “Make in India”. It will provide advanced information, enhances lead-time essential for saving lives and property in event of natural disaster associated with severe weather.

It will also provide detailed information on storm’s internal wind flow and structure as compared to conventional radars which are only able to track and predict cyclones. Polarimetric capability of this radar will significantly help to improve accuracy of rainfall estimation leading to accurate and timely flash flood warnings. With its help, severity of weather systems can be quantitatively estimated and more precise advanced warnings can be generated for saving human lives and property.

Government to set up Cyclone Warning Centre in Kerala

Union Ministry of Earth Sciences has announced to set up Cyclone Warning Centre in Kerala’s capital Thiruvananthapuram. It also proposed to set up C-band Doppler weather radar at Mangalore, Karnataka. This comes in view of recent heavy rainfall and concerns over extreme weather activities in future.

Cyclone Warning Centre

The centre will be equipped with state- of-the-art infrastructure including forecasting tools to provide daily weather alerts, issue weather warnings and coastal warnings or bulletins (for fishermenetc). It is expected to be functional within a month and will cater to the needs of Kerala and Karnataka states. It will further strengthen tpresent forecasting activity in India Meteorological Department’s existing office in Thiruvananthapuram.

At present, IMD has six cyclone warning centres, four along east coast at Chennai (Tamil Nadu), Visakhapatnam (Andhra Pradesh), Bhubaneswar (Odisha) and Kolkata (West Bengal), and two along west coast at Ahmedabad (Gujarat) and Mumbai (Maharashtra).

C-band Doppler weather radar

It is proposed to be set up at Mangalore, Karnataka to provide nowcast alerts for severe weather, including thunderstorms triggered by heavy rain for the next 2-3 hours. This radar will cover northern Kerala and Karnataka. It is expected to be installed by the end of next year. Currently, there are two Doppler radars in Kerala at Kochi and Thiruvananthapuram, which cover central and southern districts, respectively. With addition of this new radar, entire state will be covered for monitoring rainfall and severe weather events.
