This study aims to understand the patterns of spatial distribution of snowfall by Siberian High in the Honam region in Korea. In the Honam region, Siberian High induces snowfall dominantly. There is a huge amount of snowfall in the westward of the Noryung mountain ranges to the Wert coast in the Honam region affected by northwesterly wind directly from the Siberian High. The westward of the Noryung mountain ranges such as a heavy snowfall region has a various pattern of distribution of snowfall due to topography. The coast region has a large amount of snowfall by sea effect. And, snowfall amount is decreased from the coast to the inland plain. However, in front of mountain, snowfall is increase by reason of a forced ascending air to the mountain. In general the region where frequently appear a cumuliform cloud has a large amount of snowfall. A cumuliform cloud is frequent in the mountainous region in inland, the coast, and the inland plain in order Snowfall is intense in the coast and the mountainous region, and weak in the inland plain. In the mountainous region, a cumuliform cloud induced tv a forced ascending air by reason of topography generates snowfall mostly. This fact is the main difference with snowfall in the mountainous region and the coast region. In the result, in the Honam region, snowfall distribution and snowfall pattern are various, according to geographical climate factor such as sea and topography. The heavy snowfall region in the Honam region is divided into the coast region affected by sea effect and the mountainous region affected by topography effect.

This study is about the co-relationship between the directional orientation of the houses and the geometric direction in the Korean traditional villages. The major mountain in the back of the village and the front mountain ranges give the most important influence for the direction of the houses. This paper, therefore, tries to identify how the houses of villages facing South-west direct the orientation. The village, where the natural environment face the South-west village, solves the problem by facing major direction rather than one all direction. All houses observe and respect the circumstance of geomantic surrounding to the extant that almost no houses revise its direction without any geomantic reference. This kind of research let us know the relationship between the natural direction, the direction of geomantic surrounding, and the direction of houses in traditional Korean villages.

The purpose of this study is to classify the Korean precipitation regions on the basis of the characteristics of extratropical cyclonic precipitation. From now on, extratropical cyclone is called cyclone in short. By using factor analysis and Ward method in cluster analysis, precipitation regions on the basis of the characteristics of cyclonic precipitation are classified The principal data used in this study are daily precipitation records obtained from 60 weather stations of the Korea Meteorological Service during the ten years($1981{\sim}1990$), and weather charts published by the Japan Meteorological Agency. The results obtained in this study are summarized as follows: (1) In the factor analysis using 43 variables which have relation to the extratropical cyclonic precipitations, They are seven factors whose eigenvalues are above 1.0. This explains 86 percent of total amount. The first factor explains the characteristics of precipitation in the middle-west area and its contribution degree has the highest 10.9 percent. (2) According to the cluster analysis method of Ward, extratropical cyclonic precipitation regions are classified seven macro regions(such as Kyungki and North Youngseo, Youngdong and Ullungdo, Hoseo and South Youngseo, Honam and Northwest Chejudo, Southeast Chejudo, North Youngnam, and South Youngnam), 22 meso regions. (3) The characteristics of precipitation regions have relations to the path of cyclone, the direction of air inflow and the strike of mountain ranges. As the conclusion, the Central China Low brings much precipitation in the southern coast and southern area of Korea as moving to the northeastward. The North China Low moves eastward and brings much precipitation in the western area of the Taeback mountain ranges. The probability of extratropical cyclonic precipitation is the lowest in the inland of Yeongnam and the eastern coastal areas which belong to the rain shadow region. Namely, The seasonal and spatial characteristics of precipitation are closely associated with the path of cyclone and the direction of air inflow according to its passage, and the strike of mountain ranges.

20세기 초에 고토가 설정한 우리나라의 산맥체계는 지질학적 증거의 뒷받팀이 부족했다. 그후 일본 지질학자들은 그의 산맥체계에 수정을 가하게 되었으나, 수정은 그가 설정한 틀의 범위내에서 이루어졌다. 중.고등학교 지리교과서의 산맥지도가 보여주는 산맥에는 두 종류가 있다. 하나는 지반의 융기에 의해 형성된 태백.소백.낭림.함경산맥으로 산세가 웅장하고 산줄기가 분명하며, 한반도의 골격을 이루고 있다. 다른 하나는 태백.낭림의 척량산맥에서 서해안까지 길게 뻗어내린 갈비뼈 모양의 산맥들이다. 중국방향 및 랴오뚱방향의 이들 산맥은 경동지형의 고위평탄면이 해체되는 과정에서 형성된 것으로 연속성이 약하고 구간에 따라서는 확인하기 어려우며, 처음부터 잘못 설정된 거이다. 산맥지도는 산지의 분포를 보여주는 것인데. 척량산맥 서쪽에는 이들 산맥과 관계없이 분포하는 산지가 오히려 더 많다. 산맥지도에는 하천도 그려져 있으나 하천은 산맥에 가려서 잘 드러나지 않는다. 갈비뼈모양의 산맥을 아예 없애고 그 대신 하천을 뚜렷하게 그려 넣어도 훌륭한 지도가 만들어진다. 하천은 오늘날 수자원으로서 매우 중요하다.

Mountains have significant influences on the atmospheric environment. The Korean Peninsula consists of approximately 70% mountainous area with numerous mountain ranges and peaks. The initial classification of mountains in Korea was made by a Japanese scientist from 1900 to 1902. In fact, the Japanese study created too many names of mountains to maintain, which led to confusions. The purpose of this study aims to simplify the previous names and classification of mountains in the Korean Peninsula so that they can be utilized for educational and general purpose of the society and educational institutions. Through this study, we name various mountains as one name "Korea Mountains" which is classified as the secondary world-mountain class stretching from the Korean Peninsula to northeast China (southern Manchuria). The Korea Mountains connect the third class regional medium-scale mountains of Jirin, Hamkyoung, Taebaek, and the fourth mountain class, 8 small-scale ranges including the Liaoning, Yaenbaen, Hambeuk, Pyoungbeuk, Whanghae, Charyoung, Kyoungsang and Namhae Mountains. The major mountains in the Korean Peninsula are normally influenced by the general circulation of the atmosphere of the world. The atmospheric conditions are modified on the up-stream and down-stream sides; there is a need for continuous monitoring of the atmospheric environment which impacts the ecosystem and human society.

Form the results of three field surveys from May 2022 to September 2022, a total of 478 total taxa, representing 426 species, 11 subspecies, 35 varieties, four forms, and two hybrids were identified, which were categorized in 282 genera and 94 families. We identified the elevational distribution ranges of 398 taxa of vascular plants. Among them, 19 taxa were endemic to Korea, one taxon was identified as a rare plant. The floristic target plants amounted to 72 taxa, specifically two taxa of grade V, two taxa of grade IV, 16 taxa of grade III, 27 taxa of grade II, and 25 taxa of grade I. Further, 71 taxa were identified as northern lineage plants. A total of 19 taxa of alien plants were identified, with a Naturalized Index of 4.0%, an Urbanization Index of 6.6%, and three plants that disturbed the ecosystem. The result of analyzing the pattern of species richness showed a reversed hump shape with minimum richness at mid-high elevation. A cluster analysis showed a high degree of similarity between adjacent elevation sections that are geographically adjacent with similar habitat environments. Warmth index in the Gakho mountain ranged from 57.2℃·month to 84.2℃·month. Our results provide basic data on vascular plants and valuable information on elevational distribution ranges of current plant species in the Gakho mountain, which could serve as a baseline for comparison of the shifts in elevation under future climate change.

Korea's traditional Sokgasans(a artificial rock mountain) are elements of our excellent rock garden culture that have been inherited from Goryeo Era to Chosun Era. This study is to analyze how the culture of Sokgasans in the Goryeo and the Chosun Eras has been has been representated the implications and inherited in terms of historical aspects. Korea's traditional Sokgasans, which were created in the Goryeo Era by imitating the landscape of mountain ranges, created a small artificial mountain made of oddly shaped stones, imitating a real mountain. People in those days would reproduce mountain landscapes through a miniaturization technique, enjoying the pleasure of deep mountains and valleys as they lay on their gardens at home while having an aesthetic experience of the landscape that supported their emotional stability and healing. The inner side of these Sokgasan was intended to represent the world of the Taoist hermit with miraculous powers in terms of utopia, expressing 5 Ak mountains(Song Shan, Taishan, Huashan, Heng Shan and Hyeong Shan) where the mountain of 3 Gods(Youngju, Bongrae and Bangjang) wishing for 'No aging and living long' and idea of the Taoist hermit with miraculous powers are concentrated beyond the beauty of form in the landscape itself. In addition, people could refine their minds by practicing the Confucianist lesson of loving the mountain and water by watching the Sokgasan and imitating 'Famous mountains and lakes" from China and they had been changed and advanced embracing various implications in inner side of Sokgasans. Korea's traditional Sokgasans not only made it possible for people to experience aesthetic landscapes as a practical element of the scenery but also had deep symbolic implications that go beyond their formal beauty and were sublimated as an ideational space of unlimited imagination.

Black-billed magpies (Pica pica) are a highly sedentary species due to their short and round wings, which are not adequate for long distance flights. We investigated geographic variation in the vocal signals of magpies residing in South Korea and Japan (subspecies sericea). Based on the magpie's limited dispersal ability, we predicted that the variation in vocal signals of black-billed magpies could be explained by geographic barriers such as mountain ranges and straits. We analyzed four-syllable chatter calls of magpies from five localities in South Korea, which are separated by mountain ranges (Seoul, Daejeon, Daegu, Gwangju, and Busan), and two island localities separated from the mainland by straits (Jeju in Korea and Saga in Japan). We found significant differences in the characteristics of magpie chatter calls recorded in the seven localities, and the variation pattern was independent among the variables. Mainland-island differentiation and north-south differentiation were observed. In general, magpies on Saga were the most distinctive. North-south differentiation was observed among the Korean mainland localities. However, the pattern was not related to the presence of putative geographic barriers. We hypothesize that the patterns of geographic variation in the structure of magpie chatter calls residing in South Korea might have been shaped by a sudden expansion of magpies followed by low level of local isolation, which may have led to vocal differentiation. Along with elucidating the vocal environment of Korean magpie populations, more extensive sampling is needed to clarify the functional aspects of geographic variation in the vocal signals of Korean magpies.

Tulips are bulbous geophytes that have considerable commercial value worldwide. This genus primarily originated in the Tien Shan and Pamir-Alai mountain ranges, which surround the Ferghana Valley. The Ferghana Valley is home to five sections of the genus Tulipa L, represented by 23 taxa (22 species). However, there is a lack of detailed information about the distribution of Tulipa species in the natural geographic area of the Ferghana Valley. Therefore, to address this knowledge gap, we comprehensively investigated the spatial distribution of all Tulipa species in the valley. To assess the spatial distribution, the entire area was divided into 32 squares consisting of four latitudinal and eight longitudinal zones. The results showed that latitudinal zones B and C with 15 and 13 taxa, respectively, along with five longitudinal zones (A5, B3, B4, C2, and C3) with 5 to 10 taxa were hotspots for this genus. Additionally, the spatial distributions of the species in terms of the corresponding state borders, mountain ranges, endemism, and conservation issues were assessed. The findings of this study provide comprehensive information about the distribution of Tulipa species to assist with conservation initiatives ultimately to ensure the survival of various species.
