Abstract :In this study the characteristics of fog events were examined at Çarşamba International Airport in Turkey. Historical meteorological observations were used between the years of 2008 and 2017. Fog events were classified by a simple conceptual model on fog formation process. Fog types, visibility, duration, wind direction and speed, sea surface temperature were reviewed. Results show three main fog types; classified, radiation, advection and cloud base lowering. No fog events were observed between July and September, whereas the most foggy periods are between the beginning of January and the end of May. This corresponds with the advection fog period. Sea surface temperature and weather temperature during fog onset was found to highly correlate with each other.  The return period of dense fog for two years was determined to be 8.27 hours. Light, calm and eastern directions of wind were detected during the most of the fog events. Fog onset and dissipation times were figured out in monthly scale and the effect of solar radiation is clearly seen with the onset and dissipation processes. Determined characteristics of fog in Çarşamba airport can be useful for future modeling studies.
