探测环境变化对汤阴站气象要素的影响

Impact of Meteorological Observation Environment Change on Meteorological Factors of Tangyin Station

气象探测环境是整个气象探测工作的前提和基础,气象探测环境的破坏,严重影响气象资料的代表性和准确性。对汤阴县气象局1964～2008年的温度、风速、日照、降水、相对湿度等气象资料进行分析,分析探测环境变化对气象要素的影响。结果表明,测站环境变化导致年平均气温增加,且随时间序数增加明显,年平均风速、日照时数、相对湿度减少,对年降水量变化影响不大。

The meteorological observation environment is the premise and foundation of meteorological detection, the damage of meteorological observation environment would seriously affect the representativeness and accuracy of meteorological data. This article analyzed the temperature, wind speed, sunlight, precipitation, relative humidity and other meteorological data of Tangyin Station, and then studied the impact of observation environment on meterological factors. The results indicated that the environmental change of the observation stations led to the increase of annual average temperature, while decreased the annual average wind speed, sunlight hours and relative humidity, and it had Little influence on annual rainfall amount.
