摘　　要：[目的]分析即墨国家一般站迁站前后各气象要素观测资料的差异。[方法]利用即墨站新站与旧站2014年1~12月同期实测的气象资料,采用统计分析方法,对比分析了即墨站迁站前后气压、气温、相对湿度、风速的差异,并对产生这种现象的原因进行分析。[结果]新站址本站气压、相对湿度均低于旧站址,气温与旧站址相比呈正负距平变化趋势;风速高于旧站址。气象要素出现明显差异的主要原因是新旧站址海拔高度、地形地貌、探测环境及测站下垫面性质不同等原因造成的;且海拔高度及探测环境的不同是引起气象要素有差异的主要原因。[结论]该研究为预报业务中气象要素的准确预报和气候分析、气象服务、科研工作中资料的正确使用提供参考依据。[Objective] To analyze the differences of meteorological observation data in Jimo National General Station before and after station moving. [ Method] Based on the meteorological data in the new and old stations from January to February 2014, statistical analysis method was used to compare the air pressure, temperature, relative humidity, wind speed before and after station moving. The reasona for this phenomenon were analyzed. [Result] The air pressure and relative humidity in new station were both lower than those of tile old station. Compared with the old station, air temperature showed positive and negative anomaly change trend; wind speed in the new station was faster than that in the old sta- tion. The significant differences in meteorologieal elements were caused by the differenees in altitude, topography, acquisition environment and eharacterisfies of the underlying layer between the new and old stations. Among them, altitude and acquisition environment were the main reason for the differences in meteorological elements. [ Conclusion] This research provides theoretical basis for the climatic analysis, meteorological service and scientific research in meteorological elements.
