Each year, the south coast of Korea is badly damaged from storm surge. The damages are greatly dependent upon the local peculiarities of the region where the storm surge occurs. So, in order to prevent/reduce recurrence of the disaster, it is very important to investigate the fluctuation characteristics of the storm surge height, related to the local peculiarities at each coastal area where occurrence of the disaster is expected. In this paper, using the numerical model, the storm surge was simulated to examine its fluctuation characteristics at the Gyeongnam coast (southeast coast of Korea). Typhoons of Sarah (5914), Thelma (8705) and Maemi (0314), which caused terrible damage to the coastal area in the southeast coast of Korea in the past, were used forstorm surge simulations. Moreover, the storm surge due to virtual typhoons, which were combined the characteristics of each proposed typhoons (Maemi, Sarah, Thelma)with the travel route of other typhoon, was predicted. As expected, the results revealed that the storm surge heights are enhanced at the coastal regions with the concavity like a long-shaped bay. Also, the storm surge heights, due to each typhoon, were compared and discussed at major points along the Gyeongnam coast, related to the local peculiarities, as well as the characteristics and the travel route of typhoon.

This study was carried out to find a way of improving the windproof capability of greenhouse foundations. Generally, greenhouses are often collapsed due to the strong winds, because they are very light weight structures. In such a critical situations, the foundations are very often subjected to uplift and vibration at the same time. This paper describes both the wind disaster of greenhouses by the typhoon FAEY and the uplift resistance of greenhouse foundations. Followings are the results obtained from this study ; Judging from the view point of year round cultural aspects, it is recommended that some measures be taken for the preventions of greenhouse film ruptures because greenhouse structural damages are found to be directly associated with the local rupture of cover film. In the case of surveyed area, movable pipe-houses or pipe-houses of 1-2W type were found to be completely destroyed when the maximum instantaneous wind velocity was over 30m/sec or so. In the case of movable pipe-houses, the uplift resistance of greenhouse was expected to increase with the increase of pipe diameter and/or the embedment pipe length. But at present situations there is a limitation in raising the uplift resistance of movable pipe-house, because pipe diameters as well as pipe lengths customarily selected by farmers are quite a much limited.

A recent dramatic increase of natural hazards in the Korean peninsular (KP) due to typhoons have raised necessities for the accurate typhoon prediction. Ieodo ocean research station (IORS) has been constructed in June 2003 at the open ocean where typhoons pass frequently, aiming to observe typhoons before the landfall to the KP and hence to improve the prediction skill. This paper investigates the importance of measurements at the IORS in the typhoon research and forecast. Analysis of the best track data in the N. W. Pacific shows that about one typhoon passes over the IORS per year on the average and 54% of the KP-landfall typhoons during 59 years (1950-2008) passed by the IORS within the range of the 150-km radius. The data observed during the event of typhoons reveals that the IORS can provide useful information for the typhoon prediction prior to the landfall (mainland: before 8-10 hrs, Jeju Island: before 4-6 hrs), which may contribute to improving the typhoon prediction skill and conducting the disaster prevention during the landfall. Since 2003, nine typhoons have influenced the IORS by strong winds above 17m/s. Among them, the typhoon Maemi (0314) was the strongest and brought the largest damages in Korea. The various oceanic and atmospheric observation data at the IORS suggest that the Maemi (0314) has kept the strong intensity until the landfall as passing over warm ocean currents, while the Ewiniar (0603) has weakened rapidly as passing over the Yellow Sea Bottom Cold Water (YSBCW), mainly due to the storm's self-induced surface cooling. It is revealed that the IORS is located in the best place for monitering the patterns of the warm currents and the YSBCW which varies in time and space.

It is suggested that what kinds of key points are in order to decrease that calamities has suffered by typhoons that attacks annually from July to October in Korean peninsula. In considering to influence directly or indirectly huge calamities for Korea during 10 years with from 1991 to 2000, it is recorded that attacking times are 37.2% In August among total limes, 28.7% in July and 25.5% in September respectively. Especially the number of victims of lives and amount of calamities of properties are marked annually mean 142 persons and $6,111{\times}10^{10}$ won from 1990 to 1999, and similar to only 49 persons and $6,454{\times}10^{10}$ won in 2000.

Currently, according to the climate change, serious damage by Typhoon has been occurred in the world. In this respect, the research on the damage prediction model to minimize the damage from various natural disaster has been conducted in several developed countries. In the case of U.S, various damage prediction models of buildings from natural disasters have been used widely in many organizations such as insurance companies and governments. In South Korea, although studies regarding damage prediction model of hurricane have been conducted, the scope has been only limited to consider the property of hurricane. However, it is necessary to consider various factors such as socio-economic, physical, geographical, and built environmental factors to predict the damages. Therefore, to address this issue, correlation analysis is conducted between various variables based on the data of hurricane from 2003 to 2012. The findings of this study can be utilized to develop for predicting the damage of hurricane on buildings.

최근 세계적으로 기후 변화에 따라 태풍으로 인한 피해규모가 커지고 가속화되어 많은 피해를 받고 있는 중이다. 이에 몇몇 선진국의 경우, 태풍을 포함하여 다양한 자연재해로부터 건물에 미치는 손상을 최소한으로 하기 위해 건축물 피해액 사전예측 모델에 관한 연구가 진행되고 있는 추세이다. 하지만, 국내에서는 외국에서 개발된 프로그램을 사용하기에는 태풍의 크기나 영향력에서 많은 차이가 나므로 국내의 특성에 적합한 모델이 필요한 실정이다. 또한, 국내의 연구들은 태풍의 특성만을 고려하여 진행되고 있으나 태풍은 폭우와 강풍을 동반하는 복합재해로서 태풍의 특성뿐만 아니라 지리, 사회경제, 건설환경 등 다양한 요인을 고려하여야 한다. 이에 본 연구에서는 태풍에 따른 지역별 건물피해액 영향요인을 도출하고 회귀분석을 활용한 건물피해액 예측모델 개발을 목적으로 한다. 향후 본 연구의 결과는 미국의 HAZUS -MH와 같이 국내에서 태풍에 따른 피해를 예측하기 위한 모델 개발을 위한 자료로 활용될 것이다.

최근 빈번하게 발생하는 이상기후 현상은 수자원관리에 많은 어려움을 주고 있으며 예상치 못한 기상관련 재난피해를 야기하고 있다. 특히, 기후변화에 의해 점차 태풍의 세력이 강력해짐에 따라 태풍은 위험기상으로 인지된다. 본 연구의 주요목적은 태풍으로 인하여 발생하는 강우특성 및 종관기후학적 분석을 수행하는 것으로 일본 지역특별기상센터(Regional Specialized Meteorological Center Tokyo Typhoon Center, RSMC)에서 제공하는 1973년부터 2012년의 6시간 간격 최적경로(best track) 자료를 사용하여 우리나라에 상륙한 태풍사상만을 대상으로 태풍의 상륙 지속시간(내습시간)을 총 4개의 시간구간으로 구분하여 각 내습유형에 따른 강우특성 및 종관기후학적 분석을 수행하였다. 본 연구를 통한 결과는 태풍의 진로 및 이동속도를 예측 가능한 현 시점에서, 우리나라 태풍내습시 내습유형에 따른 홍수방어 및 사전대피와 같은 재해관리 측면에서 매우 유용한 정보를 제공할 것으로 사료된다. 향후 연구로서 본 연구를 통해서 확인된 기상학적 패턴을 활용하여 단기 태풍강수량 모의기법 개발이 필요할 것으로 판단된다.

In the case that construcion period is delayed because of the force majeure such as a typhoon or a flood, the owners in general should compensate the damages caused by those. But with exception the weather worsening of ordinary level is paid by contractors, while that of exceptional level by the owners. It is critical that it is difficult to distinguish objectively between ordinary and exceptional level weather worsening. Although the term of "ordinary" itself is too abstractive, we can reduce the disputes between owners and contractors by setting the appropriate and objective standard of distinction. For example in the case of rainfall it may be the standard of distinction whether the days of actual rainfall exceed those of average rainfall or not. If the days of actual rainfall don't exceed those of average rainfall contracters should pay the damages because it is distinguished with a ordinary level weather worsening. Besides the standard of distinction in another weather worsening such as severe cold/hot, strong wind etc. which have a effect on delaying the term of works could be settled as a similar model.
