| 摘要: |
| 利用济南市1951～2006年地面气象观测资料,对济南市霾日数的变化规律进行了统计分析,并结合地面风速和气压场形势对霾与气象条件的关系进行了分析。结果发现:1980年代～1990年代霾日数最多,近几年有下降的趋势;秋冬季霾日数较多,夏季较少;霾发生的天气型主要有冷高压型、低压槽型等;污染物PM10的浓度与霾的发生有密切关系。 |

| Abstract: |
| In this paper,the climatic statistical characteristics of annual number of haze days in Ji′nan,Shandong province,are analyzed using the station observation data from 1951 to 2005,and the surface situations favorable to forming haze are analyzed based on surface wind speed and pressure.The results show that the number of haze days is very high from 1980's to 1990's with more than 100 days,significantly descending since the year 2000;further more,there are more haze days in winter and autumn than in summer and spring;the main surface weather pattern for forming the haze is that the Ji′nan is under the control of a cold high pressure and a low pressure trough;there is important effect of PM10 on haze weather. |
