Abstract: Based on the warning information issued by the Sichuan Provincial Meteorological Observatory in 2023, by conducting sampling surveys, the digital evaluation and grading standards were established to assessed the dissemination quality of meteorological warning information released via provincial-level new media platforms in Sichuan. Optimization approaches, such as streamlining release processes and standardizing content, were proposed. The results indicate that among provincial meteorological new media platforms, Weibo achieved a "Good" rating in dissemination quality, Toutiao was rated "Marginally Qualified", while WeChat and Douyin were rated "Unqualified". Cumbersome release procedures, inadequate technical support, and frequent system failures led to delayed dissemination and non-standardized releases. Weibo and Toutiao demonstrated advantages in rapid dissemination and broad coverage, whereas WeChat Official Accounts and Douyin excelled in targeted.
