IMD turning 147, celebrate achievements in weather forecast accuracy, climate services – New Delhi News

“With a humble beginning in 1875, the IMD has marched forward with various milestones and paradigms to serve the society,” it mentioned in a press release on Thursday.

“IMD is celebrating 147th Foundation Day on 14th January 2022 and the function will be organised virtually at Mahika Hall, Ministry of Earth Sciences,” it added.

Other than enchancment in the weather forecast accuracy, there was enhancement in climate services, weather forecasting services, Numerical Weather Prediction modelling and meteorological observations.

The IMD sais that 33 Doppler Weather Radars are operational throughout the nation with 4 being commissioned in January 2022 at New Delhi, Leh, Mumbai, and Chennai.

“A very high resolution city scale air quality model ‘ENvironmental information FUsion SERvice (ENFUSER)’ has been operationalised for Delhi. Hourly air quality forecast for 72 hours of all criteria pollutants (PM10, PM2.5, O3, CO, NO2, SO2) is generated for the domain at 30 metre spatial resolution.

“Impact Based multi-hazard Forecast (IBF) and threat-based mostly warnings legitimate for subsequent 5 days prolonged to complete nation for all sorts of extreme weather at metropolis, district and meteorological sub-division ranges,” it added.

“Dynamical net-based mostly resolution help system for influence-based mostly forecast of cyclones has been developed by the NDMA in collaboration with the IMD and the system is put in in the IMD,” the IMD said.

On automation of generation of cyclone warning bulletins for aviation, ports etc, it said: “Besides, computerized era and show of coastal weather observations, coastal weather forecast for the subsequent 5 days, coastal weather bulletin and site-particular coastal forecast for 325 areas and nowcast for 138 stations.”

Under climate service, a multi-model ensemble forecast scheme for monthly/seasonal rainfall and temperature commencing from April 2021 along has been introduced that will give a probabilistic prediction of the spatial distribution of rainfall and temperature. A climate monitoring and prediction services for south Asia based on above scheme has also been enhanced.

Under weather forecast accuracy, Probability of Detection (POD) for heavy rainfall warning with 24 hour lead period is 74 per cent in 2021, which has improved by 51 per cent in year 2021 as compared to their skill between 2002-20. False Alarm Rate (FAR) and Missing Rate (MR) are 26 per cent in 2021, which has improved by 21 per cent and 53 per cent, respectively, in 2021 as compared to their skill between 2002-20, the IMD added.
