The objective of the present study is to characterize the local climate of slope forests, a field of research which has received little attention so far. For this purpose two approaches have been chosen. The first approach was the actual investigation of concrete research areas, the second one a literature research. It became apparent that literature about the climate of slope forests is rather limited. Relevant findings could only be obtained from the Ph.D. theses of LAZAR 1978 and the diploma thesis of PAPESCH 2007.For the actual investigation, three research areas in the Eastern Alps were identified, which represent the specific climatic conditions of a slope forest in terms of geomorphology and vegetation very well. All three research areas were investigated regarding relative humidity and air temperature. The global radiation and the influence of the general weather situation, however, were investigated only for the Gesäuse mountains, the only research area for which a data set of two years was available.The results of the study show that the climate conditions of slope forests are more balanced and homogenous in comparison to shallow valley and basin locations. There is less diurnal variation of the temperature, resulting consequently in lower extreme values, and the relative humidity is constantly very high all year round. Due to the relief of the Gesäuse mountains the values for global radiation are constantly low, while differences of course are highest during winter and lowest during summer season. Most interestingly, the study reveals a significant influence of the general weather situation on the local climate. Local climatic differences are highest during fair weather periods, lower during poor weather conditions and almost not observable during intense bad weather periods. In summary, the climate of slope forests can be characterized as cool-moistly with balanced temperature curves and a higher risk of fog formation.
