The research against Youngdong area Bronze Age settlement structure the condition where the investigation against the area and the remains which are limited becomes accomplished and Only the dwelling site will be investigated from the early settlement of most and recognition there is not a possibility which it will investigate synthetically. The Early settlement to the time which reaches the size of the settlement is small and From Bangnae-ri phases the house possession area increases inside the hill and it follows on south and if dwelling site numbers under increasing, from the aspect where the size of the settlement is magnified seems and it is a position. The Middle settlement currently was confirmed as the beginning from the room village A ruins, it investigates a settlement structure to, the increase of data is necessary. Is Pottery with clay stripes, phases the Later Settlement which Dwelling site, Storeage, Earthenware Kiln, Ditch enclosure and Tomb, the Public dwelling site back large scale Pottery with clay stripes settlement of formation will be investigated from Bangdong-ri settlements which correspond to Songhyun-ri settlement which is a hill characteristic settlement which is located in rivers circumference and the higShland characteristic settlement to provide the data the cultural aspect and character and a settlement structure of Bronze Age postscript and it will be able to grasp.

This study was conducted to investigate the effects of local climatic conditions on the annual increment of Korean white pine planted in Gapyung and Yaungdong. For this, stand variables such as mean DBH, mean height, basal area per hectare, and volume per hectare by stand age were measured and summarized for each locality. Based on these statistics, annual increments for 8 years from stand age 10 to 18 were calculated for each of stand variables. A topoclimatological technique which makes use of empirical relationships between the topography and the weather in study sites was applied to produce normal estimates of monthly mean, maximum, minimum temperatures, relative humidity, precipitation, and hours of sunshine. Then, the yearly climatic variables from 1990 to 1997 for each study site were derived from the spatial interpolation procedures based on inverse- distance weighting of the observed deviation from the climatic normals at the nearest 11 standard weather stations. From these estimates, 17 weather variables such as warmth index, coldness index, index of aridity etc., which affect the tree growth, were computed on yearly base for each locality. The deviations of measured annual increments from the expected annual increments for 8 years based on yield table of Korean white pine were then correlated with and regressed on the yearly weather variables to examine effects of local climatic conditions on the growth. Gapyung area provides better conditions for the growth of Korean white pine in the early stage than Youngdong area. This indicates that the conditions such as low temperature, high relative humidity, and large amount of precipitation provide favor environment for the early growth of Korean white pine. A ccording to the correlation and regression an analysis using local climatic conditions and annual increments, the growth pattern of Gapyung area corresponds to this tendency. However, it was found that the relationship between annual increments and local climatic conditions in Youngdong area shows different tendency from Gapyung. These results mean that the yearly growth pattern could not sufficiently be explained by climatic conditions with high variance in yearly weather variables. In addition, the poor growth in Youngdong area might not only be affected by climatic conditions, but also by other environmental factors such as site quality.

The change in fuel moisture in accordance with the number of days after rainfall is an important factor in predicting forest fire dangers and supporting forest fire rangers. Therefore, in order to clear up these forest fire occurrence conditions, forest fire danger levels for surface fuel 0.6 cm or lower, 0.6~3.0 cm, 3.0~6.0 cm, and 6.0 cm or above by fallen leaves layer, humus layer, soil layer, and diameter after rainfall of 5.0 mm and higher in accordance with tree density in 2008, 2009 Spring/Autumn Young Dong region have been analyzed. Research showed an approximate 17 % fuel moisture which is a dangerous forest fire occurrence level after 5 days from rainfall in medium-density areas and 3 days after rainfall in loose-density areas of Spring time in the fallen leaves layer. On the other hand, the humus layer showed a 40 % or higher fuel humidity even after 6 days from rainfall regardless of the season, while the upper and lower parts of the soil layer had a little change. In loose-density areas with 0.6 cm or less surface fuel per diameter in Spring time, the fuel humidity displayed a dangerous level in fire forest occurrence after 3 days, and 4days in medium-density areas, and for loose-density areas with 0.6~3.0 cm surface fuel per diameter in Autumn time it showed a dangerous level in forest fire occurrence after 3 days, and for medium-density areas, 5 days. In the case of 3.0~6.0 cm of fuel moisture per diameter in both Spring and Autumn times, even after 6 days, low and medium-density areas showed that they maintain fuel moisture and therefore the dangers of forest fires were very low, and in the case of 6.0 cm or higher, it showed 25 % or higher fuel moisture even after 6 days from rainfall regardless of the season.

A heavy (93 mm hr^-1) rainfall event accompanied by lightning occurred over Gangneung in the Yeongdong region of South Korea on August 6, 2018. This study investigated the underlying mechanism for the heavy rainfall event by using COMS satellite cloud products, surface- and upper-level weather charts, ECMWF reanalysis data, and radiosonde data. The COMS satellite cloud products showed rainfall exceeding 10 mm hr^-1, with the lowest cloud-top temperature of approximately -65℃ and high cloud optical thickness of approximately 20-25. The radiosonde data showed the existence of strong vertical wind shear between the upper and lower cloud layers. Furthermore, a strong inversion in the equivalent potential temperature was observed at a pressure altitude of 700 hPa. In addition, there was a highly developed cloud layer at a height of 13 km, corresponding with the vertical analysis of the ECMWF data. This demonstrated the increased atmospheric instability induced by the vertical differences in equivalent potential temperature in the Yeongdong region. Consequently, cold, dry air was trapped within relatively warm, humid air in the upper atmosphere over the East Sea and adjacent Yeongdong region. This caused unstable atmospheric conditions that led to rapidly developing convective clouds and heavy rainfall over Gangneung.

폭설은 짧은 시간에 많은 양의 눈이 오는 기상현상으로, 자연재해에 속하며 각종 피해를 유발한다. 우리나라는 주로 산지가 많고 삼면이 바다로 둘러싸인 지형으로 폭설의 발생 및 영향은 국지적으로 차이가 많이난다. 이에 우리나라 폭설의 지역별 위험도를 이해하기 위해서는 체계적인 지역구분과 연구가 필요하다. 본 연구는 우리나라 폭설의 지역별 위험도를 분석하기 위해 지난 39년 겨울철동안(Oct-Apr, 1971-2010) 68개의 지상기상관측소에서 측정한 일별 최심신적설량을 이용하여 우리나라 대설지역을 바탕으로 크게 울릉도, 영동 해안북부(속초와 강릉), 서태백산맥(춘천, 홍천, 양평, 원주 등), 소백산맥북서부(부여, 보은, 대전 등), 남해안 (해남, 완도, 장흥 등)의 폭설지역으로 세분화하였다. 폭설지역을 기상청의 대설특보 기준에 따라 대설주의보(5cm이상)와 대설경보(20cm이상)가 발령됐던 기간으로 빈도분석을 시행하였다. 대설주의보의 발생일수는 총 5,712일로 전체 폭설 발생일의 68%를 차지한다. 이 중 대설경보의 발생일수는 총 1,976일로 전체 폭설 발생일의 23%를 차지한다. 울릉도에서는 대설주의보의 발령일수가 총 602회로 가장 눈이 많은 지역으로 나타났으며, 그 반대로 가장 눈이 적은 지역인 남해안은 3cm이상일 경우에 대설주의보를 발령하며, 이 지역에서의 대설주의보의 발령일수가 지역별 평균 21회였다. 영동북부해안에서는 대설주의보의 발령일수가 지역별 평균 180회, 서태백산맥에서의 대설주의보 발령일수가 지역별 평균 87회, 소백산맥북서부에서의 대설주의보 발령 일수가 지역별 평균 122회로 우리나라의 폭설지역에 속하는 것으로 나타났다. 각 관측소의 39년 겨울철 최심 신적설량을 대설주의보와 대설경보의 빈도수에 따른 지역별 위험 지역을 IDW (Inverse Distance Weighting) 기법을 이용하여 공간 분포도를 작성하였다. 본 연구의 결과는 폭설 위험 지역의 지역별 빈도 분석 결과를 위험 분포도로 도시화하여 매년 반복적으로 발생하는 폭설로 인한 피해 경감 및 사회 경제적 안정에 기여할 수 있을 것으로 사료된다.

최근 세계적으로 기상이변에 의해 한파와 폭설이 발생하고 있으며, 이로 인한 피해를 예측하기 어려워 졌다. 우리나라의 대설피해는 지역별로 상이해 강설 특성을 파악하기 위해 강설자료와 과거의 기상현상자료를 분석하여야 한다. 대표적인 대설피해로 설압피해, 적설피해, 착설피해와 간접피해로 분류 되며 시설재배면적에 가장 많은 영향을 미치는 설압피해는 쌓인 눈의 압력으로 인하여 파손 및 붕괴를 유발한다. 본 연구에서는 과거 재해연보 자료(1994년~2018년)와 기상청에서 제공되는 적설자료를 활용해 대설피해 관련 자료를 수집 및 분석하여 온실에 손상을 입힐 수 있는 적설심을 분석하였다. 로지스틱 회귀분석을 위한 자료 구축은 재해연보의 피해기간을 기반으로 하여 종속변수로 사용하였다. 이후 적설심자료를 최심신적설로 변형하였으며 온도와 함께 독립변수로 사용하였다. 우리나라의 대설 사례가 많은 영동지역은 강설빈도가 높아 대설 방지대책 및 대설 연구자료가 다른 지역에 비해 많은 것으로 판단된다. 이에 따라 최근 빈도가 증가하고 있으며 대설피해 사례가 10건 이상이고 관측지점이 피해지역과 가까운 지역, 적설관측자료가 연속적으로 관측되어 있는 남원, 보령, 장수, 부안을 공간적 범위로 선정하였다. 연구의 결과로 대설 피해 재난관리가 가능한 적설심 기준 설립에 도움을 줄 것으로 판단된다.
