Surface ozone concentration trends and it is relationship with weather types in the country (2001–2010) – sciencedirect

This paper assesses the temporal variations of surface ozone concentrations throughout the period 2001–2010 in 3 parts of The country with various geographical and socioeconomic features (northern coastland, central inland and northeast inland), along with its link to atmospheric circulation. Particularly, daily surface atmospheric patterns within the aforementioned regions are characterised using NCEP/NCAR reanalysis data as well as an objective classification plan to be able to read the relationship between synoptic weather types and daily ozone levels. The outcomes reveal that tropospheric ozone concentration includes a inclination towards a rise throughout the study period, both during daytime and night time. Furthermore, generally, this upward trend is viewed throughout all the seasons. The observed trends are consistent with a reported loss of NOX emissions while increasing in surface solar radiation throughout the 2000s in The country. However, interestingly, median concentrations were statistically considerably reduced days with anticyclonic climate conditions compared to the remainder of meteorological situations, while days having a directional weather type demonstrated greater median amounts of ozone concentration, with maximum values in days with northern and eastern component. Because of the harmful effect that ozone is wearing human health, the connection between synoptic weather patterns and daily ozone levels proven within this work may potentially be utilized for applying pollution level alert protocols based on forecast weather types.
