中国气象局发布人工智能气象服务系统“风和”

Core Viewpoint - The China Meteorological Administration has launched an AI meteorological service system named "Fenghe," which aims to transform and upgrade meteorological services through intelligent applications [1][5]. Group 1: System Features - "Fenghe" allows users to input weather-related queries and receive automated responses, providing personalized suggestions across various scenarios such as travel, health, and logistics [3]. - The system comprises five main modules: Meteorological Knowledge Center, Model Plaza, Meteorological AI Toolbox, Intelligent Agent Factory, and Evaluation Laboratory, enhancing its capabilities in understanding service needs and generating content [3][4]. Group 2: Technical Framework - The design of "Fenghe" is based on a unique "1+1+N" technical framework, integrating a foundational model with professional meteorological knowledge and a large-scale meteorological service corpus of 550 billion tokens [4]. - The system utilizes advanced technologies such as LoRA for fine-tuning and reinforcement learning from human feedback (RLHF) to improve its reasoning capabilities and service adaptability [4]. Group 3: Development and Collaboration - "Fenghe" was developed by the Public Meteorological Service Center of the China Meteorological Administration, in collaboration with universities and research institutions, as part of a broader initiative to digitize and modernize meteorological services in China [5].
