| Description | Based on the case study in Císařská Cave (Moravian Karst), it was tested the impact of external wind on airflow dynamic. Time series of the cave airflow, external wind, and cave/external temperature (signals) were monitored at the lower entrance of the cave during an upward airflow ventilation mode. The periods of the oscillations in both signals (3.8 to 13.3 minutes in the cave airflow and 5.5 to 9.2 minutes in the external wind) were inconsistent. The correlation between both signals was statistically insignificant. The cross correlation did not show any time shift between both signals. These results rather question the generally presumed impact of external wind on cave airflow. |
