ABSTRACT

In winter season, at the inclined talus slope of the north side of Mt. Mudeung, there are holes (Warm Wind Holes; WWH) with no artificial heating, which are warmer than the surrounding area. These holes are usually referred as the wind hole (Poong-hyul in Korean). More precisely speaking, it is referred so when warm air comes out of the entrance of wind holes during the winter season. The effect of winter warming in wind holes in relation to the outside climate has not been well explained. This study, conducted from January 2014 to february 2016, observed and analyzed the annual variations of temperature/humidity of wind hole inside and outside. Based on the result of this analysis, I found several characteristics as follows. First, the annual average temperature/humidity of the WH10 (In) showed 12.01°C/96.12% during two years, while WH19 (Out) showed 7.59°C/84.5%. Second, the difference in maximum temperature during the period was 23.25°C in summer season, but it was 43°C in winter season. This reveals that WWH event has an outstanding phenomenon than cold wind hole event in Mt. Mudeung. This phenomenon is assumed to be caused by the effect of thermal mechanism between inside and outside of wind holes. In other words, it is changed from latent heat to changed sensible heat. In this way, Wind holes zone of Mt. Mudeung is a continuum which is formed by a set of column joint, talus slope, is a infrequent topographical landscape that creates a natural warm hole phenomenon.
