Characteristics and Causes Analysis of a Heavy Air Pollution in Hunan Province in November 2016
摘要
Abstract
Based on the air quality automatic monitoring data and meteorological observation data, the characteristics and causes of a heavy air pollution occurred in November 2016 in Hunan Province were analyzed in this paper. The results showed that the heavy pollution was a typical exogenous input process with a transmission characteristic from north to south. The polluted air masses were transported to the Hunan area under the function of northerly airflow in the lower layer. Meanwhile, due to the adverse weather conditions in Hunan area including stable atmospheric stratification, low wind speed near ground, high relative humidity and no effective precipitation, the polluted air masses could not be effectively diluted, diffused and cleaned in this region, which lead to the occurrence of heavy air pollution.关键词
