In the present work, the interaction between temperature, relative humidity, wind speed, and wind direction was studied in the atmosphere of Patras port, and the following were found: The interaction between temperature and air particle concentration was synergistic in the absence of wind direction, this result being however false. The actual effect of temperature in the presence of wind direction was antagonistic in line with most of the authors of the international bibliography; i.e., increase of the temperature level resulted in a decrease of particle concentration per unit volume (cm³). On the other hand, increase of the relative humidity increased the particle concentration per cm³, while the interaction between temperature and relative humidity was also antagonistic; i.e., increase of temperature decreased accordingly the relative humidity, and vice versa. Similarly, the interaction between wind speed and relative humidity was also antagonistic and statistically significant. It is emphasized that the wind direction played an important role in determining the antagonistic or synergistic nature of the interactions between the meteorological factors, and especially, in controlling quantitatively the results (or outcomes), of the above interactions.
