Description
The present study deals with climatic condition in the Abukuma limestone cave, Northeast Japan, based on the results of micro-meteorological observations carried out in the summer of 1996 and the winter of 1997.<br>In the closed upper level of the cave, wind velocity were almost 0m/s in the summer of 1996 and in the winter of 1997. Breeze blew occasionally from the entrance of the lower level and the exit of the middle level in the summer. In most cases wind blew into the lower level, but a part of it blew from the exit of the middle level in winter. At the lower and middle level, air temperature and humidity were lower in the winter than the summer, because of the effect of air streams from outside into the cave. On the other hand, higher air temperature and higher carbon dioxide concentration appeared at the closed upper level of the cave in the summer of 1996 and in the winter of 1997. Air temperature increased in accordance with the increase number of visitors in the cave. Daily maximum and minimum air temperature increase in mid-August because of the largest number of visitors. After mid-August, it began to decrease gradually. In winter, air temperature rose by visitors at the only upper level. In conclusion, at the upper level, the relations between the daily numbers of tourists and air temperature, the cumulative number of tourists and carbon dioxide concentration showed a significant correlation.
