基于气象大数据云平台的区域站监控预警平台设计
Design of Regional Station Monitoring and Warning Platform Based on Meteorological Big Data Cloud Platform

随着气象现代化高速发展，区域气象观测站在全国建设得到了扩大发展和应用，自动气象观测站实时的观测资料越来越及时，对标“监测精密，预报精准，服务精细”，对增强测预警手段和决策服务也提出了更高的要求。根据气象业务对突发灾害性天气监控、预警发布的需要，采用JavaScript和html5作为开发工具，开发了基于气象大数据云平台的市-县级区域气象观测站监控预警平台。采用HTML的Canvas绘制菏泽市地图信息，叠加市、县界、区域气象观测站图层，从气象大数据云平台的接口获取区域气象观测站的实况资料，实现小时温度、降水、风向、风速的实时显示和实时访问，当气象要素达到气象预警标准时可触发实时报警；同时可直观观察各个区域气象观测站点的过去24小时温度、降水、风速、风向气象要素演变曲线。该平台对提高气象区域站点数据利用率、区域站运行监控、中小尺度的灾害性天气系统监测等方面发挥了不可替代的作用，对提高气象部门防灾减灾能力，更好的为当地政府服务决策发挥着重大的作用。
With the rapid development of meteorological modernization, regional meteorological observation stations have been expanded, developed, and applied nationwide. The real-time observation data of automatic meteorological observation stations is becoming more and more timely, and the benchmark is “precise monitoring, accurate forecasting, and precise service”. This also puts forward higher requirements for enhancing measurement and warning methods and decision-making services. According to the needs of meteorological business for monitoring and warning release of sudden and catastrophic weather, a city county regional meteorological observation station monitoring and warning platform based on meteorological big data cloud platform has been developed using JavaScript and HTML5 as development tools. Using HTML Canvas to draw map information of Heze City, overlaying layers of city, county boundaries, and regional meteorological observation stations, obtaining real-time data of regional meteorological observation stations from the interface of the meteorological big data cloud platform, achieving real-time display and access of hourly temperature, precipitation, wind direction, and wind speed. When meteorological elements meet the meteorological warning standards, real-time alarms can be triggered; At the same time, it is possible to visually observe the evolution curves of meteorological elements such as temperature, precipitation, wind speed, and wind direction at various regional meteorological observation stations over the past 24 hours. This platform has played an irreplaceable role in improving the utilization rate of meteorological regional station data, monitoring the operation of regional stations, and monitoring small-scale catastrophic weather systems. It has played a significant role in improving the disaster prevention and reduction capabilities of meteorological departments and better serving local government decision-making.
