Doppler radars of varying frequencies — S-band, C-band and X-band — are commonly used by the IMD to detect and track the movement of weather systems, cloud bands and gauge rainfall over its coverage area of about 500 km.

The radars guide meteorologists, particularly in times of extreme weather events like cyclones and associated heavy rainfall.

With the radar observations, updated every 10 minutes, forecasters can follow the development of weather systems as well as their varying intensities, and accordingly predict weather events and their impact.

An X-band radar is used to detect thunderstorms and lightning whereas C-band guides at the time of cyclone tracking.
