  • The Weather Research and Forecasting (WRF) model was designed to identify the role of the Taebaek Mountains in the occurrence of heavy snowfall in Yeongdong area with a strong northeast wind on January 20-21, 2008. To this end, in addition to the control simulation with the realistic distribution of the Taebaek Mountains, a sensitivity experiment that removed the orography over the Taebaek Mountains was performed. The control simulation results showed that the resulting wind field and precipitation distribution were similar to what were observed. Results from the sensitivity experiment clearly demonstrates the presence of orographic lifting on the windward slope of the mountains. It is concluded that the altitude of the Taebaek Mountains is the main controlling factor in determining the distribution and amount of precipitation in the Yeongdong area for the case of heavy snowfall in January 2008.

  • This study analyzes the spatial distribution of the highest level terrace which can be regarded as an initial land surface before the uplift of the Taebaek Mountains and estimates spatial characteristics of the incision and uplift rates around the Mountains. The altitude above the riverbed of the 54 highest level terraces seems to be greatly influenced by the incision of large stream and their elevation shows a high correlation with the uplift of the Mountains. The elevation of the terraces in the north and middle parts decreases westward with a rate of 5~6 m/km and meets with the sea level at area 100~120 km apart from the Mountains. Therefore, it can be suggested that the west coast of Korea might have generally experienced subsidence during the Quaternary. The elevation of the terraces suggests that area with a direction of N-S or NNW-SSE from Yeoryang-myeon, Jeongseon-gun to Taebaek-si shows the highest uplift rate around the Mountains and area with a direction of N-S connecting Girin-myeon, Inje-gun and Pyeongchang-eup, Pyeongchang-gun also indicates a high uplift rate.

  • 태백산맥에서 발견된 Saussurea속의 신식물을 태백취(S. grandicapitula)로 기재하였다. 우리나라 특산인 본 종은 크기가 70-100cm에 달하는 장대한 식물로, 잎 뒷면이 창백한 녹색이며, 적갈색의 얽힌 털이 엽병에 나고, 수개의 두화가 짧은 화경에 달리며, 구형의 커다란 총포에는 갈색의 얽힌 털이 밀생하고, 포편은 뒤로 젖혀지기도 하는 특징을 가져서, 한반도 북부나 일본의 다른 종들과는 명확히 구별된다. 이는 태백산맥의 눈 많은 환경에 적응 진화한 종으로 생각된다.

  • 본 연구는 경기, 강원 지역을 대상으로 감입곡류절단 지형의 공간적 분포 특성을 검토하였다. 강원도에서도 높은 산지지역인 정선군 및 인제군을 주로 흐르는 내린천 및 동대천 등의 하천에서 곡류절단면의 분포 밀도가 가장 높았다. 곡류절단의 발생은 제4기 동안 반복적으로 나타났으며. 빙기와 간빙기 사이의 기후 변동기에 집중된 것으로 추정된다. 지질별로는 퇴적암에서 분포 빈도가 가장 높고, 화성암에서 가장 낮았다. 지질구조로 볼 때, 태백산맥으로부터 서쪽 $11{\sim}20km$ 거리에 가장 많이 분포하며. 적종하천이나 적종하천에 유입하는 지류의 하구부, 즉 단층선에 직교하는 하천에서 곡류절단이 가장 활발하였다. 태백산맥에서의 거리와 해발고도와의 관계는 영서하천에서 매우 뚜렷하고, 하상비고 및 절단면 면적과의 관계에서는 태백산맥에서 서쪽 12km를 기준으로 동서로 갈수록 값이 작아진다. 기반암 종류에 대한 해발고도. 하상비고, 하천차수와의 관계는 공통적으로 퇴적암 지역에서 값이 가장 높으며, 화산암 지역에서 가장 낮다.

  • This study tries to identify distributional characteristics of stream incision rates at 23 points in the northern part of the Taebaek Mountains. Soyang-gang, Naerin-cheon, Odae-cheon, Dong-gang and upper reaches of Okdong-cheon Rivers closed to the Range show higher incision rates and the rates clearly decrease with distance from the Range. Therefore, the incision process in the northern part of the Range has been greatly influenced by uplift around the Range, and the Sobaek Mountain Range seem to play a role in the incision process. Limestone areas show lower incision rates due to degradation of terrace surface by dissolution. This study suggests that local hydrological, geological and geomorphological conditions can be regarded as an important factor in stream incision rates, although stream incision rates are greatly influenced by regional uplift.

  • A sensitivity study has been performed using ARPS (Advanced Regional Prediction System) version 5.2.10 in a downslope windstorm case of 12-13 February 2006. The purpose of this study was to find out the role of the inversion layer of temperature mainly in relation to the strength of the downslope winds over the Yeongdong region located downstream of the Taebaek mountains. Under the conditions of N (Brunt-$V{\ddot{a}}is{\ddot{a}}la$ frequency)=0.008 and N=0.016, the effects of the presence of the inversion layer, its variation of height of the layer, and the depth of the layer were identified. The sensitivity experiments suggested that the inversion layer effected the downstream wind speed of the mountains under both conditions of N=0.008 and N=0.016, and notably when the inversion layer was located near the mountain crest the downstream wind speed of the mountains was strong (~ $27ms^{-1}$) only under the condition of N=0.016. In addition, when the atmosphere was rather stable (N=0.016) and the depth of the layer was relatively thin (765 m) the downstream wind speed of the mountains was the strongest (~ $30ms^{-1}$) among the sensitivity experiments.

  • 실험지역으로 선정된 거제도와 남해도에 대해 Yamada(1999)의 산치차수구분을 시도해 보았으며, 그 결과를 바탕으로 산지차수구분을 남한 전 지역에 확대·적용하였다. 남한 지역의 최고 산지차수는 5차수였는데, 설악·태백산지, 지리·덕유산지, 영남알프스산지 모두 3곳으로 확인되었다. 4차수 산지는 10곳, 3차수 산지는 87곳에 나타난다. 5차수 산지는 대략 한반도의 융기축과 관련이 있는 것으로 판단되며, 4차수와 3차수 산지의 분포는 2차산맥과 같은 북동-남서의 방향성을 지니고 있다. 한편 하천차수법칙과 마찬가지로 차수별 산지 개수, 면적, 비고의 로그함수 값이 차수에 대해 선형관계를 이루고 있다. 차수별로 구분된 산지 중에서 기존의 산맥체계에서 고려하지 않은 산체들을 확인할 수 있었는데, 이들은 한반도의 지체구조를 보다 자세하게 이해하는 근거로 활용될 수 있다. 국립공원 및 도립공원은 대부분 5, 4, 3차수 산지에 분포하고 있다. 특히 속리산국립공원이 남한 지역의 대표적인 두 산체인 지리·덕유산지와 설악·태백산지를 연결하는 생태축의 중요한 연결고리 역할을 하고 있음을 확인할 수 있었다. 이는 산치차수구분법이 지니고 있는 지형학적 의미뿐만 아니라 실용적 가치를 시사해준다.

  • "Gangwon Yeongdong Wind Experiments (G-WEX) Pilot Study: Downslope windstorms in the Taebaek Mountains, South Korea" is promoted based on joint organization by Gangwon Regional Office of Meteorology and National Institute of Meteorological Research and participation by 12 institutions to understand the mechanism in development of Yeongdong wind phenomena. The special observation (G-WEX) involved total of 5 intensive observations in March 2020 and April 2020. To collect the data necessary for the research on Yeongdong wind phenomena, (1) high-resolution surface observation network was used to examine surface wind and (2) atmospheric soundings were observed by using Rawinsonde, Wind profiler, Wind Lidar, and Drone. This study covers the detailed information on the special observational experiments for downslope windstorms in the leeward of the Taebaek Mountains, named as the Yeongdong wind, including the observational strategies, experimental designs, and pilot studies during the Intensified Observing Period (IOPs). According to 2020 G-WEX observation results, downslope windstorms were observed in 2~3 km of upper atmosphere when the strong winds happened around the top of the mountain near Daegwallyeong. Also, dry adiabatic expansion related to downslope windstorms caused temperature rise and led to formation of an inversion layer in altitude below 2.5 km. Bands of strong wind were located right under the altitude where downslope windstorms are observed with temporal rise of the temperature. As these are preliminary observation results, there needs to be continuous related researches and high-resolution weather observation.

  • If 《Bailuyuan》 is a piece that reflects the trend of changing Chinese contemporary literature after the 1990 reform and the opening up of socialism, 《Taebaek Mountain》 is a literary masterpiece that shows the peak of the people and coincided with subject controversy in the 1980s. These two pieces of literature were based on a common experience swayed by the encroachment of Japanese imperialism, and they became best sellers in Korean and Chinese literary circles in the 1980s and 1990s. Based on their similarities, this paper focused on and took a closer look at character modeling in the two texts. In these books, the investigators also discuss how the main characters of Bailuyuan and Taebaek Mountain are portrayed, and how this portrayal strategically works to realize the theme of the text as well as the literary significance, value, and expected effects of the comparison between these two pieces of literary work.

  • Some part of the route in KEPCO 765kV transmission line being constructed passes through a high mountain area which is 800m above the sea level (Taebaek, Sabuk area in Gangwon province). This area is the top part of Taebaek mountains corresponding to the backbone of korean peninsula and has lots of snow during the winter season because the winter seasonal wind gone up along the mountainside of Taebaek Mts. meets open air of the East sea. KEPCO has experienced 63 faults of T/L between 1968 and 1993 in this area, which is a very serious problem. Especially 154kV Hwang-Ji T/L fault in 1990, 2 was a unprecedented case which needs to be analyzed carefully to take proper measures. After reviewing ice and snow loading conditions and analyzing the fault of Hwang-Ji T/L, we're going to determine the revisement of ice and snow loading condition in this area to increase reliability of 765kV transmission line.
