| 摘 要： | 环境空气中污染物浓度不仅与污染源的排放有关,更与气象条件的变化密不可分。在不利气象条件下,空气中污染物浓度可能在极短时间内就出现峰值,造成城市空气质量迅速恶化。通过对天津市2005年11月上旬连续出现的空气污染实证,分析了主要气象因子(温度、相对湿度、能见度)与空气污染物(PM10、SO2、NO2)之间的关系,探讨了稳定天气条件对空气环境质量的影响。

| Abstract: | The pollutant concentration in the environmental air not only relates with the emission of pollutant source,but also ties in the weather factors.In the bad weather conditions,the pollutant concentration cumulated to a peak value in a short time,and worsened the environmental air quality soon.In this text,on the continuous air pollutions occurred in the first ten days of Nov.2005,the correlativity between primary weather factors(temperature,relative humidity,visibility and air pollutants(PM_(10) SO_2 NO_2)was analysed,and the influence of steady weather conditions to air quality was discussed. |
