- 摘要:
- 为揭示北京一次持续重污染过程的气象成因,利用北京地区常规及特种气象资料、风云二号C卫星数据及PM2.5观测资料,分析了高低空环流形势、局地气象要素的动力和热力结构对其的影响。结果表明:过程期间,高空以西北或偏西气流为主,地面受高压后部弱气压场和低压辐合区控制; 地面呈现小风或静风的状态; 850 hPa以下相对湿度维持在80%以上; 存在多层逆温且维持时间长; 不利于污染物扩散的气象条件是PM2.5前期积累的主因,而局地环流所形成的风场辐合线北抬是PM2.5浓度在后期短时内爆发性增长的关键因素。
- Abstract:
- In order to reveal the meteorological conditionsfor a continuous heavy pollution process in Beijing, the observation data from regular and special meteorological stations, FY-2C satellite and PM2.5 concentration data were used to analyzes the upper and lower circulation pattern and the influence of the dynamic and thermal structure produced by local meteorological elements.The results showed that during the process of heavy pollution,northwest or west flow was dominated on the high latitude and the ground was controlled by the low atmospheric pressure field of the rear high pressure and the low pressure convergence zone.Moreover,the ground showed a state of light wind or calm,below 850 hPa, the relative humidity maintained at above 80%, and there was multiple-layer inversion and it had maintained for a long time.The unfavorable meteorologic condition of pollutant diffusion is the principal cause, the accumulation of PM2.5 concentration at the earlier stage of the process, influenced by the Beijing topography and local circulation.The surface convergence line formed by the surface flow field in Beijing area elevated northward, which is the key factor for the explosive growth of PM2.5 concentration in a short time in Beijing area.
