“IMD (India Meteorological Department) already installed its first S-Band Doppler Radar in Mumbai located at Navy Nagar, Colaba (South Mumbai) on 29th October 2010. Another similar radar is expected at Mumbai International Airport (T2) in coming years. The power S-Band weather forecaster Doppler radar which was installed instead of a China Made Metstar is a perfect huge electronic DOM like device for medium to long range weather forecasting within city limits. Lets understand how such radars help save city from floods and droughts like the one experienced in 2005..”

How Doppler Radar Works
This special and powerful radar costs about 10 to 12 crores is designed by ‘Bharat Electronics Limited’ and ‘Indian Space Research Organization’ was designed specially for Kochi (Formerly ‘Cochin’) and will be used at Mumbai Airport area. A huge round shaped DOM on top of a iron tower also portable on building’s terrace area like the one installed on Archana Building at Navy Nagar. It uses electronic waves which are transmitted back billions of radios waves from clouds and around surface areas, It senses, captures and returns back the predicted data to IMG upon hitting the fine moisture particles. With this data, IMD can keep updated with the upcoming weather and climatic changes and be prepare for any emergency conditions. 16 Storey Archana building’s terrace was specially modified to get this first Doppler of Mumbai installed at height of 68 meters.
Named after an Austrian Physicist ‘Christian Doppler’, This radar is a real time forecasts of Monsoon thunderstorms, It can also predict rainfall starting days, Its intensity in monsoon days and is a very good device for medium and long range forecasting. It can accurately and more precisely predict and returns information at range of 250 km distance area. Information like Mapping the water drops size inside clouds, Rainfall intensity, Upcoming possible Thumderstorms, High Tides
, Speed at which rain and wind goes, and many other information is received which helps BMC and other departments be prepared for upcoming monsoon. Doppler also helps taking more correct desicions on the processes like Cloud seeding
(Artificial Rainfall) in Mumbai.
