泰和国家气象观测站迁站对比观测数据差异分析

Analysis of differences in observation data of Taihe National Meteorological Observation Station relocation and comparison

文章合理使用通用差值统计方法,通过对比分析泰和国家气象观测站新站址与旧站址观测2018年预报表数据库,计算最低与最高气温、相对湿度及2min平均风速的标准年差值及差值平均值等;采用相符率统计新旧两站风向一致率。基于通用差值统计方法,对比新、旧两站气象资料进行对比分析研究,详细了解变化的主要原因,以便为后续工作和气象站迁站后的预报服务提供相应数据支持。结果表明,新迁地址的平均气温比旧地址低;最高气温低0.1℃,最高气温低0.8℃;与旧址相比,新址年平均风速高0.6m/s;新旧两站年最多风向均为N,整体风向一致;年降水量相差106.6mm,月降水量6月相差最大。技术人员通过对新、旧两站多类型气象要素进行分析研究,为后续实现精准预报气象及提升科研业务气象资料奠定坚实的基础,也为泰和国家气象站延续气象资料序列提供依据。

The paper reasonably uses the general difference statistical method to compare and analyze the 2018 forecast table database of Taihe National Meteorological Observatory’s new and old stations,and calculates the standard annual difference and average difference values of minimum and maximum temperature,relative humidity,and 2-minute average wind speed.Use the consistency rate to calculate the wind direction consistency rate between the new and old stations.Based on the universal difference statistical method,comparative analysis and research are conducted on the meteorological data of the new and old stations,in order to gain a detailed understanding of the main reasons for the changes and provide corresponding data support for subsequent work and forecasting services after the relocation of meteorological stations.The results show that the average temperature measured at the newly relocated location is 0.5℃.The highest and lowest temperatures are 0.1℃and 0.8℃respectively.Compared with the old site,the average annual customs of the new site are great then 0.6m/s.The maximum annual wind direction for both new and old stations is N,and the overall wind direction is consistent.The difference in annual precipitation is 106.6mm,with the maximum difference in monthly precipitation in June.Technicians analyze and study multiple types of meteorological elements at the new and old stations,laying a solid foundation for achieving accurate weather forecasting and improving scientific research operational meteorological data in the future.They also provide a basis for the continuation of meteorological data sequences at Taihe National Meteorological Station.
