诸城迁站观测资料变化分析

Analysis on the Change of Observation Data of Zhucheng Migration Station

目的:了解站址迁移前后观测资料序列的差异,为正确使用迁站前后观测资料提供依据。方法:利用诸城市2017年现用站和拟迁站、参考站气温、降水、相对湿度和风速,采用表格、线性曲线图、差值比较和趋势比较等方法进行了统计分析诸城市现用站和拟迁站气温、降水、相对湿度和风速的变化检验各要素的差异。结果:诸城站现址观测资料区域一致性较差;现址观测资料序列完整、区域一致性较差、均一性较好;新址和现址气温、相对湿度平均值差异不显著,风速差异异常显著。结论:新址和现址风速一致性最差,表现出明显的局地性特点;相对湿度一致性最好,观测数据较稳定;著性检验结果表明,新址和现址气温、相对湿度平均值差异不显著,风速平均值差异显著。

Objective: To understand the differences in the sequence of observation data before and after the site migration, and to provide a basis for the correct use of observation data before and after the migration. Methods: Using the existing stations and proposed stations in 2017, the reference station temperature, precipitation, relative humidity and wind speed, using statistical methods such as tables, linear graphs, difference comparison and trend comparison, the current stations in the cities were statistically analyzed. The changes in temperature, precipitation, relative humidity and wind speed of the proposed station are tested for differences in various factors. Results: The consistency of the current observation data of Zhucheng Station is poor;the sequence of observation data at the current site is complete, the regional consistency is poor, and the uniformity is good;the average temperature and relative humidity of the new site and the current site are not significantly different, and the wind speed difference is abnormally significant. Conclusion: The wind speed of the new site and the current site is the worst, showing obvious local characteristics. The relative humidity is the best and the observation data is stable. The results of the test show that the average temperature and relative humidity of the new site and the current site are different. Not significant, the wind speed average difference is significant.
