| 摘 要： | 利用广东省惠州市区2013—2016年逐日、逐时的环境和气象资料, 研究了珠江三角洲(简称“珠三角”)东侧惠州市臭氧污染特征及其与气象条件关系。结果表明:惠州市臭氧污染具有明显的月和季节变化特征, 10月臭氧平均浓度最高, 臭氧超标日和污染日主要出现在7—10月。惠州市臭氧浓度日变化呈单峰变化, 06—08时最低, 最大值出现在午后14—15时。臭氧浓度变化和气象条件关系密切, 低浓度臭氧大多出现在气温较低、相对湿度和风速较大、云量较多伴有降水、日照时数较小的天气, 臭氧浓度超标多出现在气温较高、相对湿度和风速较小、云量较少一般无降水、日照充足的天气。惠州市臭氧超标主要出现在地面和低空偏西风下, 这可能与惠州市处于珠三角城市群下风向的区域污染输送有关。

| Abstract: | Based on the hourly environmental and meteorological data of Huizhou from 2013 to 2016, the characteristics of ozone pollution and its relationship with meteorological conditions are studied for Huizhou in the east of the Pearl River Delta. The results show that the ozone pollution in Huizhou has obvious characteristics of monthly and seasonal variation. The average concentration of ozone in October is the highest, and the days of the ozone concentration in exceed of the standards are mainly from July to October. The diurnal variation of ozone concentration in Huizhou showed a single peak change, the lowest concentration was observed at 06:00—08:00 a.m., and the maximum concentration was observed at 14:00—15:00 p.m. Ozone concentration is closely related to meteorological conditions, with low concentrations of ozone mostly observed with low temperature, high relative humidity and wind speed, low cloud cover and no precipitation and short sunshine duration. Standard-exceeding ozone concentration was mainly observed when westerly wind prevails in the ground and low altitudes, which may be related to regional pollution transportation downwind of the Pearl River Delta city group, as Huizhou is located in the east of the Pearl River Delta urban agglomeration. |
