ABSTRACT. Consideration of the fog regime in the airports area from Moldavia territory (Romania). In the airports area where the possibility of frequent mists and lasting fog exist, there is a risk that the aviation activity shut down for hours and sometimes for days. The paper is based primarily on the factual material represented by continually measured data during the 1961-2012 period by the weather stations witch are located in Iaşi, Bacău and Suceava airports area. Of all the airports located on the Moldova territory, the Iasi airport have lowest risk of occurrence of fog (33 days/year), and the opposite, with the highest number of days with fog, is Bacău airport (57 days/year). Annual average duration of fog case is between 5.4 hours at Iași and 8.3 hours at Suceava. In all that three airports, calculations based on long sequences of observations (1961 - 2012) have indicated that the annual number of days with fog presents a downward trend, more pronounced in Bacău and Suceava airports.
