  • The heavy snow event occurred on JAN 4, 2010 brought huge disaster such as Gimpo International Airport runway closed, heavy delays of other airport, and property damage of 16 billion won. Though this heavy snow event is involved in the general synoptic scale heavy snow forecast, it recorded too much snow amount and longer duration than expected. To explain this unusual event, we used the conveyor belt theory. By combining the synoptic scale heavy snow forecast and the conveyor belt theory, the characteristics of heavy snow event was well explained.

  • PURPOSES : This study is to investigate the countermeasures against heavy snow on road in Seoul: Focusing on Seocho 1-dong. METHODS : Since 2000, three cases of the top 10 in the highest snow fall depth in a day occurred in 2001(234mm, 156mm) and 2010(258mm) and the possibility of heavy snow is getting higher. 10 days after heavy snow fall when the snow thaws, socio-economic damages occurred often. For example, the insufficient snow removing, difficulty in patients transfer, crash accidents, injuries from a fall, the increasing cost of snow removing etc. RESULTS : For the effective deploying snow removing equipment and workers, it is necessary to understand emergency snow removing spots. Seocho 1-dong was tested because it contains mountains, hill and urban areas as well as various buildings and road types exposures. CONCLUSIONS : Based on the domestic and international heavy snow researches, the elements for vulnerability were analyzed and vulnerable areas to snow fall were derived.

  • The objectives of the on-the-spot inspection in Honam district are to find out the situation of the damages on facilities and the reason of the damages caused by heavy snow, and to suggest the preventive plan for reducing the damages from the future heavy snow. From the results of the on-the-spot inspection, plastic houses, barns and ginseng cultivation facilities are mainly damaged by heavy snow in the Honam district, and the importance of the future heavy snow preparedness measures is highly recognized in an agricultural district. In this research, 4 kinds of alternative proposals for the heavy snow are suggested.

  • This Study focuses on the binary forecast of occurrence of heavy snow in Honam area based on the MOS(model output statistic) method. For our study daily amount of snow cover at 17 stations during the cold season (November to March) in 2001 to 2005 and Corresponding 45 RDAPS outputs are used. Logistic regression model and neural networks are applied to predict the probability of occurrence of Heavy snow. Based on the distribution of estimated probabilities, optimal thresholds are determined via true shill score. According to the results of comparison the logistic regression model is recommended.

  • 본 논문은 우리나라 기원전 6년 11월부터 1928년 까지 1934년 간의 강설기록을 살펴 본 것으로서 다음과 같은 특징을 정리할 수 있었다. 첫눈 기록은 733년 7월에 신라땅과 1637년 전라도 무주에서 있었고 끝눈 기록은 6월 11일에 눈보라가 온 것으로 기록되어 한 여름에도 눈이 왔었다는 사실을 확인할 수 있다. 적설량은 척관법 단위를 써서 기록하였는데 최고 적설량은 약 열 자 혹은 한 장(장여 혹은 일장) 기록이 있었으며 자주 나타나는 큰눈 기록은 대개 4∼5자가 많이 발견된다. 단위를 치(촌)와 푼(분)까지 사용하여 기록한 바 정확성을 기하려 한 흔적도 보인다. 눈피해는 주로 인명과 가옥 등을 중심으로 기록하고 있다. 눈피해 중 인명피해로는 크게 3건이 발견된다. 1524년과 1521년에 함경도 경성 땅에서 각각 100여명과 140여명, 1670년에는 제주도에 큰눈이 내려 91명이 사망한 것으로 기록되어 있다. 첫눈이 오면 상서로운 것으로 여겨 나라에서는 신설하례(新雪賀禮) 의식을 갖고 나라의 안녕을 기원하였고, 눈이 오지 않으면 왕에게 간하여 기설제를 지내기도 하였다. 눈과 관련된 기상이변은 여러 번 발견된다. 눈 올 때 심한 천둥번개가 친다거나, 이상한 벌레들이 섞여 내린다거나 붉은 색깔의 눈이 내렸다는 기록이 있다. 검색한 결과는 단어별 건수에 있어서나 내용에 있어서나 미진한 것이다. 검색방법이나 검색에 사용해야 할 단어 중에는 좀 더 합당한 단어들이 있을 줄 안다. 차후의 연구를 위한 과제로 남기기를 희망한다.

  • 연구목적 : 최근 기후변화에 따라 여름철 태풍, 호우와 겨울철 대설, 한파 등의 기상재난이 증가하고 있다. 대설재난은 교통, 건물, 시설물 등에 다양한 피해를 발생시키기 때문에 신속한 대처가 필요하다. 대설재난이 도시 안전에 영향을 주고 있으나 우리나라의 대설재난 대처는 미흡하고, 정책 연구도 부족한 상황이다. 연구방법 : 본 연구는 대설재난이 발생할 때 신속한 도로 제설을 위하여 제설차량과 장비에 정보 통신 기술을 활용한 사례를 분석하고, 시사점을 도출한다. 연구결과 : 도로 제설장비에 정보통신기술이 적용된 장비를 부착하면 긴급 상황시 제설차량과 장비의 위치를 파악하여 인근지역의 도로 제설을 응원할 수 있다. 결론 : 본 연구의 사례 분석은 향후 지자체 제설장비의 효율적 이용을 위해 활용될 수 있다.

  • PURPOSES : This study is to suggest heavy snow risk analysis in Seoul. METHODS : Recently, the increase of extreme weather caused by global warming raises the occurrences of unpredictable natural disasters and the loss potential of human disasters by land use facilities accumulation. It is necessary to develop the risk analysis for the natural and human disasters. RESULTS : In this study, heavy snow risk analysis among natural disasters in Seoul was suggested. The spatial unit of risk analysis level was established for the lines and administrative districts. CONCLUSIONS : The risk analysis was performed using risk matrix of disaster occurrence score and disaster damage score. The components affecting the risk disaster analysis by types were analyzed and the application of heavy snow risk analysis was suggested.

  • Successive 24 snow samples, collected from a 1.2m snow pit at a site on the summit of Main Dome in King George Island, Antarctic Peninsula, were measured for heavy metals such as Pb, Cd, Cu, and Zn and other chemical species. The mean concentrations of heavy metals are 3.48pg/g for Pb, 0.10pg/g for Cd, 16.6 pg/g for Cu and 15.8 pg/g for Zn, respectively. Pb and Cd concentrations observed in our samples are very comparable to those reported for recent snow at other Antarctic sites, while Zn and Cu levels are much higher than those at other sites. The annual fallout fluxes of all heavy metals approximately calculated are, however, much greater in King George Island than at other sites. With respect to the estimates of natural contributions, sea salt spray is found to be a major contributor to Cd and Zn inputs to the snow and minor to Cu inputs. On the other hand, the anthropogenic input can account for a large part of Pb concentrations. A tentative estimate represents that local emissions could be responsible for more than half of the excess Pb flux to the snow in King George Island.

  • The results of the synoptic meteorological analysis showed that when the cold and dry continental high pressure was extended, heavy snow occurred at dawn when the upper atmosphere cooled. In particular, when the continental high pressure was extended and the upper pressure trough passed through, heavy snow occurred due to the convergence region formed in the west coast area, sometimes in the inland of the Honam area. In addition, it was verified that the changes in the humidity coefficients in the upper and lower layers are important data for the determination of the probability, start/end and intensity of heavy snow. However, when the area was influenced by the middle-latitude low pressure, the heavy snow was influenced by the wind in the lower layer (925 hPa and 850 hPa), the equivalent potential temperature, the convergence field, the moisture convergence and the topography. In Case 2010 (30 December 2010), OSTIA had the best numerical simulation with diverse atmospheric conditions, and the maximum difference in the numerically simulated snowfall between NCEP/NCAR SST and OSTIA was 20 cm. Although there was a regional difference in the snowfall according to the difference in the SST, OSTIA and RTG SST numerical tests, it was not as significant as in the previous results. A higher SST led to the numerical simulation of larger snowfall, and the difference was greatest near Buan in the west coast area.

  • The pipe framed and arch shape plastic greenhouse, which is the most popular greenhouse in Korea, is relatively weak in snowdrift. Reinforcement of rigid frame or column is required to reduce the damage from heavy snow in this type. But additional rigid frames or columns decrease light transmissivity or workability, and increase construction cost. So it is desirable to prepare some temporary poles and to install them when the warning of heavy snow is announced. This study was carried out to develop the temporary pole supporting system using galvanized steel pipes for plastic housing and to evaluate the safe snow load on a temporary pole. A pipe connector, which is inserted in the top of pipe used in the temporary pole and supports the center purline, was designed and manufactured to be able to carry the upper loads safely. And a bearing plate was safely designed and manufactured in order to carry the loads acting on it to the ground. When temporary poles of ${\phi}$ 25 pipe are installed at 2.4m interval, it shows that the single span plastic greenhouses with 5~7 m width are able to support the additional snow depth of 13.9~25.3 cm beyond the snow load supported by main frame.
