| Abstract: | The integrated assessment of the influence of air mass transport directions on the average long-term seasonal variations of
concentrations of minor gas components (MGC: ozone, CO, NO2) of the atmosphere is carried out according to the data of a number of European stations. Distributions of nitrogen dioxide
and carbon monoxide concentrations according to transport directions are similar to each other and differ considerably from
the distribution of ozone concentrations. It is demonstrated that the relationships of levels of spring and summer ozone concentrations
maxima differ considerably at all examined stations in different regions of Europe depending on different transport directions:
the summer maximum is stronger pronounced according to the data for the southern and eastern directions than according to
the data for the northern and western directions. The change of air transport directions may account for from 10% (Moscow
region) to 30–40% (the northwest of continental Europe and Ireland) variations of MGC concentration. The obtained results
point out the perspective of their use in statistical models of the forecast of MGC concentrations. |
