Core Viewpoint - The China Meteorological Administration has launched the "Fenghe" model, a billion-parameter meteorological service model that integrates AI technology and meteorological expertise, aiming to transform traditional weather services into an intelligent new phase [1]. Group 1: Technical Characteristics of "Fenghe" - "Fenghe" is a generative AI system specifically designed for meteorological services, built on a large language model architecture [2]. - The model boasts a powerful core with a trillion parameters, indicating its strong learning and expressive capabilities, allowing it to capture complex atmospheric phenomena [2]. - Through multimodal integration and generative AI technology, "Fenghe" aims to provide high-resolution, efficient, and rapid-response intelligent meteorological services [2]. Group 2: Comparison with Previous Models - Previous models like "Fengqing," "Fenglei," and "Fengshun" were primarily aimed at internal meteorological forecasting systems, focusing on enhancing the accuracy of weather predictions [3]. - "Fenghe" differs by targeting public and industry meteorological services, addressing the limitations of general models in understanding meteorological service needs and providing professional, precise, and cost-effective information [3]. Group 3: Future Applications and Public Services - "Fenghe" is expected to support various scenarios such as disaster warning, transportation, tourism, health, commerce, and energy, offering customized and detailed meteorological information services [4]. - The model will revolutionize public travel by providing unprecedented precision and scenario-based decision support, moving from traditional weather forecasts to point-to-point predictions [5]. - For example, "Fenghe" can simulate microclimates in complex areas, offering specific recommendations for outdoor activities based on detailed weather conditions [5].
