The paper presents a case study for the 9-10 January 2015 period, when foehn processes were occurred on the eastern slope of the Apuseni Mountains. With a view to establishing the synoptic context in which the phenomenon was manifested, an analysis of the atmospheric fields was used, while for determining the intensity of the process several meteorological parameters (temperature, wind and relative humidity) were analyzed along three west-east profiles across the Apuseni Mountains. The analysis points out the presence of foehn processes on the eastern part of the Apuseni Mountains, the highest thermal and hygric differences being recorded on the north-eastern part of the mountains. The most important effect of this synoptic situation was the reduction of the snow cover depth.
