Studies on the Definition of Occurrence Mechanisms of Storm, Tornado and Flood Damage Appeared by Typhoon 0613 in 2006 and their Countermeasures

0613号台风出现在菲律宾附近的东海上，越过石垣，经过东海，袭击佐世保，然后穿过日本海。最大瞬时风速在石垣为69.9 m/s，在长崎超过50 m/s。当台风位于距加拉津2000公里处时，受锋面影响，该地区出现暴雨。一场大雨和山体滑坡被调查。佐贺和长崎的盐风害非常严重，佐贺的水稻形势指数为42。盐害指数的变化规律从海边到15 km呈指数关系。通过对树木盐分含量的测定，研究了盐风害。明确了遥感数据与植被活动度研究的NDVI之间的关系。选择了抗盐害强度高的防风林。宫崎和大分县发生了5次龙卷风。龙卷风的规模为F2级，长7.5公里，宽200米，在野冈有列车被掀翻。其破坏特征是以飞物作为屋面板的二次破坏为主，且中等城市破坏较大。评估了阵风与损伤的关系。该问题是基于屋顶部分的强度。通过对天线避雷针线圈的破坏，明确了龙卷风的特征.研究了龙卷风和积雨云的出现频率以及云雨带的模拟模式。半岛和岛屿的地形对龙卷风的出现有一定的影响。介绍了长崎和北九州的海上机场的特点，并展示了老年人和残疾人对策的支持系统。通过对台风灾害的调查，以及对农业和养殖设施的调查，分析了灾害的构成要素及其对策。为降低建筑物的风险，进行了问卷调查，指出了存在的问题，并对建筑物的损坏状况进行了评估。

Typhoon 0613 was appeared on the East Sea near Philippines, crossed to Ishigaki, passed in the East China Sea, hit at Sasebo, and passed through to Japan Sea. The maximum instantaneous wind speed at Ishigaki was 69.9 m/s and over 50 m/s in Nagasaki. A heavy rain at Karatsu was affected by the front when the typhoon located at 2000 km from the place. A heavy rain and landslide were investigated. The salt wind damage was very severe at Saga and Nagasaki and rice situation index was 42 at Saga. The changing pattern of salt damage index was an exponent relation from sea side to 15 km. A salt wind damage was investigated by salt amount on trees. The relation between remote-sensing data and NDVI studied for vegetation activity were made clear. The strong windbreaks against salt damage were selected. 5 tornadoes were in Miyazaki and Oita. The scale of tornado was F2, 7.5 km length and 200 m width, and train was overturned at Nobeoka. The characteristics of damage were based on secondary damage by flying things as a roof slate, and the damage was large in middle city. The relation between gust and damage was evaluated. The problem was based on the strength of parts of roof. The characteristics of tornado were made clear by destroy of lighting rod coil of antenna. The frequencies of tornado and cumulonimbus cloud, and simulation model of rain band of the cloud were investigated. The topography as a peninsula and island was affected on appearance of tornado. The airports surrounding by sea at Nagasaki and Kitakyushu were characterized.Support system was shown for countermeasures for the aged and handicap peoples. Elements of disaster and their countermeasures were investigated by the typhoon, and a culture and agriculture facilities. The questionnaire was carried out for the decrease of risk and the problem was pointed out an evaluated status of building damage.
