FOG, A RISK PHENOMENON FOR THE RIVER TRAFFIC ON THE DANUBE-BLACK SEA CANAL

Summary/Abstract: Fog is a meteorological process quite frequent along, the Danube- Black Sea Canal, the average number of fogdays being 45-48 days a year. In the lower layers of the atmosphere, entering in contact with the activeunderlying surface, after clear warm days during which intensive processes of evaporation occur, often the fogphenomenon arises, due to the droplets of water or ice crystals which are in suspension. The average number offog days occurs differently from one season to another, the highest frequency being encountered during winterand autumn. Fog is most frequent at night, especially during the first hours after sunset and before sunrise. Wemay say that fog is a phenomenon which arises partly because of the water and because the region has an aislecharacter. During foggy days the river traffic on the Danube- Black Sea Canal is hindered or even stoppedwhen the fog is very dense.
