临河气象观测站迁移对气象要素的影响分析

文章通过对内蒙古巴彦淖尔市临河地面气象观测站迁移前、后4a的自动气象站观测要素对比分析,得出临河迁站前、后气象要素存在明显的差异:新站的年、月平均气温比旧站低、相对湿度比旧站高、风速比旧站大。旧站的观测资料仅代表城市中心局部气候状况,已经不能较好的反映本地区的气候特点;而新站则较好的反映了临河地区城郊大范围的天气气候状况。同时分析了新、旧站各气象要素差值的形成原因,期望为天气预报、气候评价、气象服务等提供数据参考。

Analysis on the Influence of Meteorological Observation Station Migration on Meteorological Elements in LinHe

through the comparative analysis of the observation element of automatic meteorological station before and after four years of linhe ground observation station migration, the meteorological elements had obvious differences before and ＇after Linhe ground observation station migration, the annual and monthly average temperature of new station was lower than the old station, the relative humidity and wind speed of new station was higher than old station. The observation data of old station only represent the local climate conditions of city, it could not reflect the climate characteristics of the region better. While the new station could reflects the weather conditions of wide suburban district of Linhe. Also, the forming reason of difference value of new and old station difference was analyzed, this article expect to provide data reference for weather forecast, climate evaluation and meteorological services.
