Winter weather conditions vs. air quality in Tricity, Poland.

摘要: The principal aim of this paper is to assess the influence meteorological conditions on variability sulfur dioxide and PM10 particulate matter concentration pollutants during winter with consideration an excess admissible standards. basis for analysis were hourly concentrations as well basic elements automatically recorded at five stations located in Tricity agglomeration, operating within weather station network belonging Agency Regional Air Quality Monitoring Gdansk Metropolitan Area (ARMAAG). covers calendar winters (December–February) years 2004/2005 through 2009/2010. both under certain conditions, i.e. air temperature relative humidity, atmospheric pressure, wind speed direction, evaluated by means cluster using k-means a group non-hierarchical method. composite effect isolated clusters determined multiple linear regression, stepwise procedure, significance level α = 0.05 0.01. individual pattern levels was partial regression coefficients. Clusters grouping highest characterised, most cases, lowest lower speed, often higher sometimes slightly anticyclonic weather. Weather had statistically significant all clusters; however, crucial role. Thermal decisive factor season 2005/2006 frequent, overnormative daily concentration, yet inversion layers upper, occurring almost every day January 2006 also influence.
