| 摘 要： | 利用1994年11月发生在山西省的持续性雾霾天气过程实况资料,计算了多种物理量,并从环流形势、形成条件和维持机制等方面进行综合分析。结果表明：①500 hPa锋区偏北,中纬度环流较平,低空850 hPa持续有暖平流向山西地区输送,是大范围霾天气持续的重要天气背景;而500 hPa阻塞形势的稳定维持,地面回流稳定,是导致...

| Abstract: | A durative regional haze and fog weather occurred in Shanxi Province in November 1994 was comprehensively analyzed based on the observed data.The results are as follows:(1) Front area at 500 hPa was located by north,circulation at mid-latitude was straight,and there was a warm advection at 850 hPa to convey continually towards Shanxi.These were the important weather background to form a large-scale haze.While blocking situation at 500 hPa maintained stably and the surface refluence was stable to form the la... |
