Abstract
On the basis of air temperature (T) monitoring, basic statistical and time series analysis was employed to evaluate thermal states of cave atmosphere variations. Long-term, seasonal and event comparative analysis as well as spectral and cross-correlation analysis was conducted. The results show the relative stability of air T in the isolated part of the cave, whereas variable air T was observed in the parts close to entrances and the surface. The distinctive seasonality in this part of the cave demonstrates that air convection is a driving force for the heat exchange between the cave and the surrounding environment. External air T and heat conducted through the rock walls are also an important factor influencing the cave climate, while heat released by the ice deposit and by water infiltrating through the cave ceiling has a negligible effect. Occasional irregular variations in daily patterns are caused by human impact.
