迁站观测资料影响程度分析

Analysis on the Influence of Station Relocation to Observation Data

利用山东省冠县气象站和莘县气象站1959～2009年的气压、气温、相对湿度、降水、风速、地面温度、日照观测记录,采用对比差值及趋势系数法,对搬迁站冠县站与邻站莘县站主要气象要素进行连续性差异分析。结果表明,1981以来冠县站探测环境受到城市化影响,使得主要气象要素较莘县站表现为气压偏低、气温偏高、相对湿度偏小、风速偏小、降水量偏多、地面温度偏高、日照时数偏少。

Based on the air pressure, air temperature, air relative humidity, precipitation, wind speed, surface temperature and sunshine ob- servation recorder during 1959 to 2009 at Shandong Guanxian observation station and Shenxian observation station, the continuous difference of principle weather elements between Guanxian observation station and Shenxian observation station was analyzed by using the comparative differ- entiation and trend coefficient method. The results showed that, acquisition environment of Guanxian observation station had been influenced by urbanization, which mainly manifested as lower air pressure, higher air temperature, lower relative humidity, lower wind speed, more pre- cipitation, higher surface temperature, less sunshine hours.
