The Doppler radar did not work on Monday when an extremely severe cyclone passed at about 120-km off the city's coastline.
After the failure of Mumbai's only Doppler radar on Monday amid the severe Tauktae storm, the Secretary of Earth Sciences Ministry announced that 5 new weather radars will be installed here. The authority highlighted that while the Doppler flop did not affect the IMD monitoring, given its access to 3 high-resolution satellite, the failure of the city's high-power antenna radar wave was 'very unfortunate'. Thus, the department has decided to install one C-band and four X-band detectors, as additional weather detectors here, in the next 3-4 months.
Mumbai's weather detection systems to get an upgrade
The IMD's S-band radar at Regional Meteorological Centre in Colaba is the sole Doppler in Mumbai and its failure to affect the monitoring of the severe cyclone Tauktae, has unnerved experts. Despite the radar's powerful antenna that can track and transmit around a 500-km radius, the Doppler did not work on Monday when an extremely severe cyclone passed at about 120 km off the city's coastline. Consequently, new weather detection systems will be provisioned in Mumbai to break the dependency on a single monitoring device.
The Secretary of the Earth Science Ministry informed that one C-band radar that can read up to 250-350 km range and 4 X-band radars, with a radius of 50 km each and high-resolution cloud capture quality, will help the Met Department monitor weather irregularities in Mumbai. He further stated that it might take up to 3-4 months to install these devices in view of the current pandemic crisis. New radars are also pipelined at Mangalore and Ahmedabad, the official added.
