The values of basic climate elements for the definite altitude (from 750 to 1,950 m) were obtained, by the application of the calculated altitudinal linear gradients characterized by the altitudinal distribution of the certain forest zones in the Kopaonik mountain massif in central Serbia. At the lower limit of the zone the average annual temperature ranges from 6.8^oC at the south exposure to 7.1^oC at the north exposure (in the vegetation period it is about 13^oC), and at the upper limit it is 1.8^oC. The average annual quantity of precipitation at the lower limit of the zone is below 776 mm at the south exposure, and it is 861 mm at the north exposure, whereas at the upper limit of the zone it is above 955 mm. The climate classification by Thornthwaite's method shows that in the analyzed altitudinal forest zone in Kopaonik the following climate types occur: midly humid (B₁) at the lower limit, extremely humid (B₄) at the altitudes ranging from 1,500 to 1,700, and perhumid (A), at the altitudes above 1,700 m. The interdependence of the occurrence and survival of the forest vegetation in this area, its distribution and altitudinal differentiation, and the climate characteristics, is proved in this research as well. Each altitudinal forest zone is characterized by the specific microclimate conditions.
