It is the principal agency responsible for meteorological observations, weather forecasting, and seismology. Again the predictions of IMD are not up to the mark as far as accuracy is concerned, as per IMD in 2016 the total rainfall would be approximately 106 %, unlike the actual rainfall which was approximately 96%. The following are the challenges IMD is facing: IMD is using Statistical model also known as ensemble model for monsoon prediction, this model as the name suggests extensively based on the data collection, and a minor fault in collecting or analyzing the data can cost IMD . Coverage of Large geographical area-data for the statistical model has been collected from a wide geographic area such as it covers the atmospheric condition of the Indian ocean, pacific ocean, Mediterranean sea, so this is very difficult Dynamic Concept-Weather and climate are very dynamic concepts constantly changing and evolving so its difficult to predict the exact nature. The intensity of Monsoon is based on a large number of phenomena such as El-Nino, La-Nina, Indian Ocean Dipole, Madden Julian Oscillation, Westerlies, Easterlies so on and so forth, So the analysis of such a huge number of the phenomenon is difficult Climate change and its Undeciphered consequences-Constantly changing climate and its unknown consequence are making the prediction more difficult. Still, IMD is in the phase of improving itself as it is changing its old Ensemble Model with New Dynamic model which is based on simulation and extrapolation and also using supercomputers such as “ADITYA” for better Monsoon predictions. 1 Reply Share Share Share on Facebook Share on Twitter Share on WhatsApp Leave an answerCancel replyYou must login or register to add a new answer.Continue with FacebookContinue with Google Related Questions Describe National Intellectual Property Rights Policy.
