Snow baseline conditions and changes for winter tourism

Croatian tourism is the most developed on the Croatian Adriatic coast and on the islands. Croatia’ s highland areas consist of parts that belong to the Dinaric Alps and other isolated mountains in the northern lowlands. These areas are suitable for tourism, both in summer and in winter. Good snow conditions in the Croatian highlands, including depth of snow cover as well as its duration allow the development of winter tourism oriented also on snow related activities such as cross-country skiing or snow mobiling rather than on alpine skiing only. This study focuses on the area of the Medvednica Mountain located in the south-eastern corner of the Alps. This is an isolated mountain in the vicinity of the Croatian capital Zagreb. But the snow regime on the Medvednica Mountain, which lies at about 1000 m, represents a very risky factor in winter tourism development plans. This is the reason why the interest in snow activities and the possibility to develop them (cost-benefit effect) depend not only on the snow regime characteristics, but also on the artificial snow production. The climatological study includes analyses of the annual course and probability of snow parameters at different altitudes and comparisons to the reference period 1961/62-1990/91. Due to users request the relationship between air temperature and relative humidity at 7 a.m. was analysed with regards to snow making purposes for the period from November to February. We used these climatological data as they are generally available and are the closest to the daily temperature minimum. At the same time concerns with climate variability and change put special emphasis on time analysis (fluctuations and trends) of snow parameters (intensity and frequency) and different meteorological parameters related to snow (air temperature, total precipitation and air pressure) during the second half of the 20th century.
