The paper presents the results of a study of the effects of a cold wave in eastern Serbia. The research was conducted in an artificially-established spruce stand in MU `Obla glava`, Sokobanja Forest Administration. The stand is even-aged, 38 years old, well-preserved with a very dense canopy closure (1.0). In late November and early December 2014, eastern Serbia was hit by a cold wave that caused serious damage and the occurrence of ice-breaks in the forests of this region. A part of the study spruce stand was directly exposed to the cold wave because there is a clearing in front of it, while the other part was protected by neighboring stands. The characteristics of the climate at the time of the cold wave were determined for the altitude of 700 m where the study stand is located. The summary of the climate was based on the study of the main meteorological elements using the method of altitudinal gradients and the study of the harmful effects of the cold wave on artificially-established spruce stands in the area. We presented the annual values and the values of the following most important climatic elements for the months of November and December when the ice wave occurred: air temperature, rainfall, and air humidity. Categorization of trees by the degree of damage was used to determine the intensity of the stand damage. The index of the stand damage was calculated using the method of Reber tus, А. Ј . et al. (1997), which was adapted to the classification of tree damage applied in this paper.
