Abstract

Because of the special topography surrounded by sea on three sides, the coastal area of Qingdao is greatly affected by the aerosol of sea salt sources, and has a significant maritime climate. Based on the meteorological observation data measured by the Qingdao seaside from September to October 2019, the correlations between the atmospheric conventional meteorological parameters of the typical sea area and the influence of meteorological parameters on the atmospheric aerosol optical parameters were analyzed. The results indicate that,(1) the relative humidity has opposite daily variation to temperature, and the change of atmospheric pressure slightly lags behind the relative humidity;(2) there is a relationship between the change of weather and meteorological parameters, that is, the parameters such as temperature and relative humidity, visibility and particle number density distribution on sunny days are significantly different from those in rainy days;(3) visibility is positively correlated with the daily variation of wind speed and temperature, and is negatively correlated with the daily variation of relative humidity. It shows that conventional meteorological parameters such as relative humidity, temperature, and atmospheric pressure are closely related to optical parameters such as particle size distribution and visibility. The above statistical analysis results have reference value for the establishment of the regional aerosol model in the coastal area of Qingdao.
