Seasonal variations of water condensation in cave environment: A case study from the Výpustek Cave (Moravian Karst)
Roč.32,č.1-2(2025)
Seasonal variations of water condensation were studied in the Výpustek Cave (Moravian Karst). Microclimatic data such as cave/external air temperatures and visitor numbers were monitored in the Škrapový Dome and exterior of the cave with one-hour step during an almost season-long monitoring campaign. Water condensation data were recorded at monthly intervals using a polished limestone tablet located in a dome near the thermometers. Long-term monitoring showed that the temperature of the cave air was controlled
by cave airflow driven by the temperature difference between the exterior and the cave, ΔTAF. Anthropogenic temperature influence appeared as peaks superimposed onto natural cave air temperatures curves and corresponded to the number of visitors. Seasonality of water condensation based on cave airflow was identified: no condensation during the UAF mode and drops of condensed water on the tablet surface in the DAF mode. Traces of calcite recrystallization were found on the tablet surface as a consequence of dissolution by the condensed water.
