雾霾天气与对流层延迟、气象因素的相关性分析

Correlative Analysis of Haze,Troposphere Delay and Meteorological Factors

对流层延迟是影响卫星定位的主要误差之一,雾霾发生在对流层,因此雾霾对对流层延迟会产生不同程度的影响,从而影响卫星导航定位的精度。本文对对流层延迟与空气质量指数之间的相关性进行研究,进一步探究雾霾的主要污染成分与气象元素之间的关系,分析促进雾霾发生的条件。结果表明,从雾霾发生到消失扩散的过程中,对流层延迟与空气质量指数间表现出较强的相关性,随着气压、风速的降低和相对湿度的增大,雾霾发生的概率会增加。

The tropospheric delay is one of the main errors that affect the satellite positioning.The haze occurs in the troposphere,so the haze will have different effects on the tropospheric delay,which will affect the accuracy of satellite navigation and positioning.The correlation between tropospheric delay and air quality index,the relationship between the primary pollutants and meteorological elements of haze,and the conditions for promoting haze here was analyzed and researched.The results show that there is a strong correlation between the tropospheric delay and the air quality index.With the decreases of air pressure and wind speed,the increases of relative humidity,the probability of haze occurrence will improve.
