Which Institute has developed an extended range prediction system of forthcoming heat waves in advance?

Pune's Indian Institute of Tropical Meteorology (IITM) researchers have developed an extended range prediction system aims at the real-time monitoring and prediction of forthcoming heat waves 2 to 3 weeks in advance. It has great potential in providing an advance indication about the onset, duration, and demise of the heat wave spell with a small spatial & temporal error with 70% accuracy. Since 2017 Indian Meteorological Department (IMD) has been using this system and it had used it in 2019 to predict heat waves. During 1981 to 2017, 22 heat wave events of the northwest, 14 southeast coastal regions and 9 regions in the northwest-southeast region were experienced for more than eight days in each region during the summer season.
