清晨6点，滇东高原天色未亮，在云南省红河州弥勒市太平街道丫普龙村的杨梅山，山顶体感温度不足10摄氏度，一场冷雨即将到来，这 里的中国气象局弥勒云贵准静止锋野外科学试验基地已亮起灯光。 1946年，气象学家张丙辰首次提出"昆明准静止锋"概念，为后续研究奠定了基础，但后续很长一段时间内，我国对云贵准静止锋的研究多 源于少数学者的自发探索。 2021年，依托国内首个聚焦云贵准静止锋研究的科学试验基地，即现在的中国气象局弥勒云贵准静止锋野外科学试验基地，陈艳和张涛分 别带领的云贵准静止锋机理与预报技术研究团队、云南省观测产品开发与应用创新团队正式组建，对云贵准静止锋有组织的观测与机理研究由 此展开。 2025年1月14日，位于云南省弥勒市的中国气象局弥勒云贵准静止锋野外科学试验基地。（杨阳 摄） 4年多来，两支团队围绕云贵准静止锋持续开展攻关研究，扎根高原锋区推进系列野外观测试验，无人机、新型地基遥感设备等先进气象 装备轮番上阵，一组组珍贵的观测数据经记录、质控和订正后，形成了高质量的研究数据集。同时，他们面向业务核心需求开展科研攻关，研 发了锋面客观判别方法、多模式评估订正及基于AI的气温智能预报等关键技术。 "走 ...

Core Viewpoint - The article highlights the significance of the Yunnan Meteorological Bureau's research on the quasi-stationary front in the Yunnan-Guizhou Plateau, emphasizing its impact on weather forecasting and the advancements made in observational technology and data accuracy [4][7]. Group 1: Research and Observational Advances - The Yunnan Meteorological Bureau has established a scientific research base focused on the quasi-stationary front, which has been operational since 2021, leading to organized observations and mechanism studies [4]. - Advanced meteorological equipment, including drones and new ground-based remote sensing devices, have been utilized to collect high-quality observational data, enhancing the understanding of the quasi-stationary front [7]. - The research teams have developed key technologies such as objective identification methods for the front, multi-modal evaluation corrections, and AI-based temperature forecasting, which have improved the accuracy of weather predictions [7]. Group 2: Impact on Weather Forecasting - The accuracy of weather forecasts in regions affected by the quasi-stationary front in Yunnan has improved by over 10% from 2021 to 2025, demonstrating the effectiveness of the research efforts [7]. - Local communities have benefited from timely weather warnings, allowing for proactive measures to be taken, such as evacuations before severe weather events, which were previously reactive [8]. - Farmers have adapted their practices based on improved forecasts, reducing the negative impact of sudden weather changes on their crops, indicating a positive shift in agricultural resilience [8].
