The system realized the automation process for the generation of life index forecasting products from local situation of Wuhu City and forecasting data,which could get the latest service products dispensing with manual intervention. The development of the system not only made the operation process of the life meteorological index of Wuhu City more time-saving and efficient,but also made the results more scientific and rigorous.展开更多
