摘要/Abstract

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。

关键词: 500 hpa环流形势, 地面环流形势, 空气质量指数(AQI), 气象条件

Abstract: The research on pollution weather classification has great significance for air quality forecast and pollution total amount control. To provide the basis for air quality forecast and early warning, the weather type that affect the air quality of Chengdu was classified based on the ground pressure situation from 2013 to 2014, then the air quality under different weather type was analyzed, and then the pollution meteorological characteristics of each weather type was studied based on meteorological monitoring data. Results showed that there are 5 weather types based on 500 hpa circulation situation, including two-trough and one-ridge type, one-trough and one-ridge type, latitude type, trough and ridge in phase type and so on, The air quality deteriorated under the control of two-trough and one-ridge type, one-trough and two-ridge type and trough and ridge in phase type. There was 10 weather types that influence air pollution based on surface pressure situation, including high pressure type, at the back of the high pressure type, at the bottom of the high pressure type, low pressure type, at the top of the low pressure type, at the front of the low pressure type, at the bottom of the low pressure type and so on. The air quality deteriorated under the control of high pressure type, at the back of the high pressure type, at the bottom of the high pressure type.

Key words: 500 hpa circulation situation, ground pressure situation, air quality index (AQI), meteorological factor
