Evaluation of Relationship Between Air Pollutant Concentration and Meteorological Elements in Winter Months

Abstract

The paper presents the evaluation of the relation between meteorological elements and air pollutants’ concentrations. The analysis includes daily concentrations of pollutants and variation of meteorological elements such as wind speed, air temperature and relative humidity, precipitation and total radiation at four monitoring stations located in the province of Lower Silesia in individual months of the winter half-year (November–April, according to hydrological year classification) of 2005–2009. Data on air quality and meteorological elements came from the results of research conducted in the automatic net of air pollution monitoring conducted in the range of the State Environment Monitoring. The effect of meteorological elements on analysed pollutant concentration was determined using the correlation and regression analysis at significance level α < 0.05. The occurrence of maximum concentration of NO, NO2, NOX, SO2 and PM10 occurred in the coldest months during winter season (January, February and December) confirmed the strong influence of “low emission” on air quality. Among the meteorological factors assessed wind speed was most often selected component in step wise regression procedure, then air temperature, less air relative humidity and solar radiation. In the case of a larger number of variables describing the pollution in the atmosphere, in all analyzed winter seasons the most common set of meteorological elements were wind speed and air temperature.

Assessing the Impact of Wind Speed and Mixing-Layer Height on Air Quality in Krakow (Poland) in the Years 2014-2015

“…For most substances, at higher wind speeds observed concentrations in the air decrease [22,25,32,45], due to the intensified dilution of pollutants. The ventilation effect is of particular importance in the heating season, during which an increased emission from household fuel combustion and petrol vehicles cause the accumulation of pollutants in the city centre.…”

“…Studies assessing the impact of selected meteorological parameters on air quality for other large Polish cities are known [5,6,8,21,33,45], but the subjected area was usually characterized by a more favourable location with better ventilation properties. Similar analysis was also carried out several times for the city of Krakow [7,25,31], but for the earlier period.…”

“…Other aspects that were studied were the environmental aspects and impacts of urban sprawl: land take and soil sealing [73,74], water consumption increase [75], surface water pollution from new traffic infrastructure [76], low emission and air pollution [77], potential of renewable energy production [78,79], landscape diversification and conversion [80,81], and changes in ecosystem benefits and services [82,83].…”

A Customized Decision Support System for Renewable Energy Application by Housing Association

“…According to the energy consumption in households, the largest percentage of the population uses solid fuels, mainly hard coal and wood. The use of energy fuels is associated with the increased exploitation of non-renewable resources and, as a consequence, negative impacts on the air quality [7,8]. In order to reduce environmental pollution, many countries have decided to use renewable energy for energy purposes.…”
