随着西安经济的快速发展,雾霾天气严重影响了人们的正常生活,雾霾问题也引起了全国人民的广泛关注。实时、全天候的GPS水汽资料已在气象领域天气预报中得到广泛应用。本文分析了雾霾的形成原因,结合临潼站的GPS水汽和雾霾资料进行了深入对比分析。研究结果表明,雾霾的形成过程与GPS水汽含量的变化密切相关,西安地区GPS水汽与雾霾指数在水汽含量较低的冬春季节存在一定的正相关性。GPS水汽资料在一定程度上可用于雾霾天气的监测与预报,特别是气象部门可依据GPS水汽含量实施人工作业改善持续雾霾天气的影响。
With the rapid economic development of Xi'an,the dust-haze weather is serious and affects people's normal life,and causes wide widespread attention. This paper analyzes the reasons for the formation of dust-haze and the correlation of GPS water vapor and dust-haze in Xi'an. The result shows the GPS water vapor and dust-haze index in Xi'an region has a positive correlation. To some extent,the GPS water vapor data can be used to monitor and forecast the dust-haze weather.
