Abstract:

Based on the air pollution processes during heating seasons from 2001 to 2010 in Shijiazhuang, and associated with the sea-level pressure fields and 500 hPa geopotential height fields, the synoptic patterns for air pollution weather were divided into four types including troughs and ridges pattern, zonal circulation pattern, transverse trough pattern and the saddle pattern. Based on the conventional observations and numerical simulation results simulated by the Weather Research and Forecasting model (WRF), relationships between growing and disappearing of haze and meteorological factors were analyzed, it came to the fact that the stable stratification and calm winds controlled by an uniform pressure field led to the continuance of the haze weather. The influence of haze on psychological health was analyzed on the basis of psychological questionnaires during the period of haze growing and disappearing. It was found that the haze affected adult mental health when it continued more than a weak, especially on compulsive, depression and anxiety.

Key words:  haze, synoptic patterns, numerical simulation, psychological health

摘要：

选取石家庄2001~2010年12月至翌年2月28次空气污染过程，结合海平面气压场和500 hPa高度场，总结出有利于霾发生的4种天气类型：槽脊型、纬向型、横槽后部型和鞍形气压场型。利用WRF模式对一次霾发展变化过程进行数值模拟，分析霾生消与气象要素间的关系，结果表明低层持续的均压场和逆温层结造成大气污染物持续累积，霾得以持续数日。在霾持续期间开展心理问卷调查，分析霾对成人心理健康的影响，结果表明持续一周的霾会对人体心理健康产生影响，其中对强迫、抑郁和焦虑3种症状影响最大。
