兰州西固工业区夏季光化学烟雾污染的气象条件
- METEOROLOGICAL CONDITIONS OF PHOTOCHEMICAL SMOG POLLUTION DURING SUMMER IN XIGU INDUSTRIAL AREA, LANZHOU
- 摘要：通过对兰州西固工业区光化学烟雾污染规律与气象条件的关系的研究表明,在高空槽后的低空弱高压控制下,西固区出现高的臭氧浓度值,此时大气层结稳定,风很小,天气晴朗,但中午有浓重烟雾,臭氧浓度峰值在中午出现。该区盆地内形成的光化学烟雾烟团水平面积达几十公里,臭氧浓度的日变化取决于太阳总辐射和大气边界层的日变化。
- Abstract：The characteristics of photochemical smog in Xigu industrial area, Lanzhou was studied. The results suggested that under the control of the slightly high pressure at low atmosphere layer followed high-altitude trough, high ozone concentrations appeared. The thick smog often happened in summer noon after rain when the atmosphere was stable, the wind velocity was low and the weather was fine. The photochemical smog formed over Xigu area covered tens of square kilometers. The daily fluctuation of ozone concentration was related to the diurnal change in solar radiation and characteristics of the boundary layer.
