Abstract

The downflowing cool air that goes outside the cavities is a known process, but barely studied. This communication incorporates preliminary results of a multidisciplinary-team research to characterize and analyze these airflows, their envi- ronmental implications and the information they provide from the interior of fractured karst massifs. In situ measurements of temperature, humidity and wind speed, have been carried out together with image captures by handheld and carried-UAV thermal infrared (TIR) cameras. Two sectors in Sierra Mágina (Jaén, S. Spain) with different geological characteristics have been studied. In both sectors, the expelled cool airflow has turned out to be a widespread phenomenon that occurs for more than 4 months a year at multiple points. The temperature of the outgoing air is almost constant for each entrance throughout the warm season, but instead it can vary from one entrance to the next. The study of this phenomenon has direct applications in speleology and risk analysis, by locating entrances and preferential fractures. In order to determine the factors inside the rock massif that control the process characteristics, future research are necessary, including its modeling.
