IMD changes technique to determine weather

The IMD has changed its strategy for issuing seasonal and monthly rainfall and temperature forecasts for the country. The new technique is based on a forecasting system called Multi-Model Ensemble (MME) that was recently developed. The MME method employs coupled global climate models (CGCMs) from a variety of global climate prediction and research organizations, including the IMD/MoES Monsoon Mission Climate Forecast System (MMCFS) model.
