'ABSTRACT In this study, the relationship between meteorological parameters and ambient air pollutant concentration in three cities of North Cyprus have been investigated for three criteria pollutants. The primary and secondary air pollutants and the meteorological parameters such as temperature, pressure, wind speed, direction, and relative humidity were analysed for a period of 2 years from 2014 to 2015. Meteorological conditions were correlated (temperature, relative humidity, wind speed, pressure) with pollutants (NO2, O3 PM10). Three cities of Northern Cyprus were selected (Famagusta, Kyrenia and Nicosia). According to the seasonal analyses and spearman rank correlation, ozone exhibits a different trend from the rest of the pollutants. A clear seasonal trend was also observed for PM10 and NO2 with maximum concentrations in the winter and minimum in the spring seasons. Also, temperature is positively correlated with Ozone and PM10 while wind speed is negatively correlated with all air pollutants. In Kyrenia, easterly winds (southeast, east, northeast) let to the highest PM10 concentration. Northerly winds let to the highest PM10 concentration in Nicosia while in the Famagusta, southerly winds (southwest, southeast, south) dominated for PM10 concentration. Particulate Matter concentration was highest in the winter seasons, followed by summer and subsequently fall and spring in all three cities. In Famagusta, days with top 10% of PM10, and NO2 concentration occur at higher relative humidity compared to days of bottom 10% of concentration. Still in Famagusta, Ozone had a distinct difference in relative humidity with lower concentrations in bottom 10% and higher concentration in the top 10%. In Nicosia, days of top 10% PM10 and NO2 concentrations occurred with higher relative humidity compared to days of bottom 10% although there exists a higher variability than top 10% for NO2 and vice versa. However, top 10% ozone concentration in Nicosia occurred at lower relative humidity with a higher variability than bottom 10%. Lastly in Kyrenia there was no fluctuation between top and bottom 10% NO2 but PM10 had a higher top 10% relative humidity than bottom 10% (low variability). Ozone had no distinct difference in relative humidity for both top and bottom 10% in Kyrenia.'
