2005年12月3日-4日香港举办了新一届冬季国际游艇展览会,这是2005年香港举办的第二个国际游艇展。香港一向实行自由贸易的市场运作机制,绝大部分的国际展览活动都交由民间的私人商业机构来举办。在游艇展览方面,香港政府引入两家私人机构同年举办国际游艇展览会,意在繁荣活跃香港的水上活动。早在2005年4月初,香港西部的黄金海岸游艇会就举办了香港第8届国际游艇展览会。才过去半年时间,12月份香港政府又在香港东部西贡的匡湖居游艇会办展, 相似文献

Data from four studies of waves generated by hurricanes are reviewed and compared. The combined dataset presents a consistent picture of the wave field within a hurricane. The wave field is more asymmetric than the corresponding wind field, mainly due to the “extended fetch” which exists to the right of a translating hurricane. This concept leads to the specification of an equivalent fetch for a hurricane which enables the use of fetch limited growth relations for the prediction of the significant wave height within a hurricane. Examination of spectra recorded within hurricanes indicates that they are remarkably similar to fetch limited forms. Relationships for the parameters defining fetch limited spectra are found to also be valid for hurricane conditions. The reason for the similarity of hurricane and fetch limited spectra is attributed to the shape stabilizing effect of non-linear wave–wave interactions, which continually reshape the spectrum to conform to the standard JONSWAP-like form. Although the wind speeds within hurricanes are very high, the spectra generated are mature, with values of non-dimensional peak frequency typical of fully-developed seas. The analysis develops a set of standard relationships which can be used to define the wave field and spectral form for use in design of offshore fixed and floating structures. 相似文献

This article examines the evacuation behavior of residents in two South Carolina communities, Hilton Head and Myrtle Beach, during the 1996 hurricane season. Two hurricanes that approached South Carolina but hit in North Carolina allowed us to study the impact of repeated “false alarms”; (evacuations ordered based on expectations of a hurricane landfall that proved to be wrong). Differences in evacuation behavior, specific information and concerns prompting evacuation, and the reliability of information sources between hurricane events are examined to determine the impact of false alarms on the credibility of warning systems. Data were derived from a face‐to‐face survey of residents 2 weeks after Hurricane Fran in September 1996. We found that the role of official advisories was more limited than reported in previous research as people sought information on more diverse sets of concerns in their decision making. Reliance on the media and the Weather Channel, in particular, for storm characteristics and advisories was an important factor in evacuation decision making during both hurricane events. The perceived lack of reliability of gubernatorial warnings coupled with dependence on the media suggests that residents find other sources of information more personally relevant. Thus, while residents do not find that officials are “crying wolf,”; they are searching elsewhere for information to assess their own risk—what does it mean to me if there is a wolf? This increased attention toward individual differences in perceived threat may become more pronounced in future evacuations from hurricanes. 相似文献

飓风浪对于船舶航行、海洋和海岸结构物的安全意义重大,分析工程区设计波要素需要考虑飓风引起的大浪。采用YoungSobey风场模型建立飓风风场,以飓风风场作为第三代波浪模型MIKE 21 SW的驱动场,对发生在大西洋的飓风IRENE引起的飓风浪进行模拟,并将模拟结果与实测浮标数据进行对比。对比结果显示,MIKE 21 SW可以很好地模拟飓风引起的极值波浪要素。 相似文献
