【摘要】：污染天气分型研究对空气质量预报、污染源总量控制等具有重要的意义。基于2013年1月~2014年12月高空及地面天气形势划分了成都市的天气类型并探讨各天气类型下的空气质量状况及其污染天气特征,以期为空气质量预报和预警提供依据。结果表明,空气污染过程中,500 hpa环流形势主要有两槽一脊型、一槽一脊型、纬向型、槽脊同位相型等,其中两槽一脊型和槽脊同位相型控制下的空气质量最差。发生空气污染时,地面环流形势可分为高压型、高压后部型、高压底部型、低压型、低压顶部型、低压前部型、低压底部型、鞍型场型、冷锋前部型和均压场型,其中高压型、高压底部型、高压后部型控制下的空气质量最差。
[Abstract]:The study of pollution weather classification is of great significance to air quality prediction and total pollution source control. Based on the upper air and surface weather situation from January 2013 to December 2014, the weather types in Chengdu are divided and the air quality and polluted weather characteristics under different weather types are discussed in order to provide the basis for air quality prediction and early warning. The results show that in the process of air pollution, there are two channels and one ridge, one trough and one ridge, one zonal pattern, and the same phase type of trough ridge, etc. The air quality is the worst under the control of two slots and one ridge and the same phase of trough ridge. When air pollution occurs, the surface circulation situation can be divided into high pressure type, high pressure rear part type, high pressure bottom type, low pressure top type, low pressure front type, low pressure bottom type, saddle type field type, cold front type and uniform pressure field type, among which high pressure type, The air quality is the worst under the control of high pressure bottom type and high pressure rear part type.
