- 摘要:
- 为了定量分析杭州市臭氧污染特征及其气象成因,利用杭州市2011-2016年气象资料和2015-2016年地面臭氧污染监测数据,对气象要素和臭氧浓度进行分析。得到如下结论:臭氧污染浓度随季节呈周期性变化,臭氧污染指数日平均值在春季达到最大值。臭氧浓度最小值出现在5:00-8:00,最大值出现在16:00左右。影响臭氧浓度的主要气象因子有相对湿度、气温、日照时数、气压等。通过逐步回归选入日照时数、平均气温和相对湿度建立了臭氧浓度预报方程。
- Abstract:
- In order to quantitatively analyze the characteristics of ozone pollution and its meteorological causes in Hangzhou, the meteorological factors and ozone concentration were analyzed by this article which uses the meteorological data of Hangzhou from 2011 to 2016 and the monitoring data of surface ozone pollution from 2015 to 2016. The conclusions are as follows: the concentration of ozone pollution varies periodically with seasons, and the daily average value of ozone pollution index reaches its maximum in spring.The minimum ozone concentration arises in the phase between 5:00 and 8:00 while the maximum value appears approximately at 16:00.The main meteorological factors affecting ozone concentration are relative humidity, air temperature, sunshine duration, atmospheric pressure, etc. By stepwise regression, the sunshine duration, average temperature and relative humidity were selected to establish the prediction equation of concentration prediction.
