Abstract:
Cotnari vineyard is the northernmost wine-growing vineyard of our country, located close enough to the northern limit
of the expanding region of the grape vine. Within this study, we analyse one of the climatic factors that, in our view,
contributes to the climatic favorability of this region for the vine plantations: the foehn. More precisely, the hydraulic
foehn, which is not mentioned in the Romanian climatology literature, although the mechanism associated with the
development of this type of foehn wind, is described for more than 40 years in the international climatological
literature. We bring arguments for the manifestation of the hydraulic foehn during winter 2013-2014 in the related
region of Cotnary vineyard on the basis of measurements accomplished at Paşcani climatologic station and at other 11
points of hourly monitoring temperature of Dealu Mare-Hârlău region. Additionally, radio-sounding data, synoptic
maps and other synoptic data of some of the meteorological indicators of foehn development are used. Local generating
mechanism, periods of occurrence, synoptic conditions associated to its generation, the intensity of temperature
difference recorded within the region and the possible effect of its development in the increase of the region’s
favourability for the vine-growing, are analysed in our study
