台风“鲇鱼”作用下南海波浪场的数值模拟研究

运用第三代海浪模式WAVEWATCHⅢ,以台风模型风场与美国NCEP风场的合成风场为驱动风场,模拟西北太平洋在台风"鲇鱼"期间的波浪变化情况。在运用卫星高度计波高资料对预报模型进行验证的基础上经进一步分析认为,台风"鲇鱼"产生的波浪在北部湾以风浪为主,涌浪较少,而在北部湾以外的南海产生的波浪以涌浪为主,涌浪波高可达3~6 m,周期为12~16 s。在台风"鲇鱼"由东向变为向北行进过程中,在南海产生的涌浪也由东向逐渐变为东北向。

长时间、长周期的涌浪,对大型船舶的系靠泊及作业会产生较大影响,可靠的波浪预报数据能够为大型船舶及港口的运营提供生产决策依据。本文基于先进的海浪预报数值模式及技术手段,针对董家口港区影响船舶安全生产作业的海浪进行精细、准确的预报、预警。通过对该港区数值模拟与海浪监测站实测有效波高进行对比,两者吻合较好,均方根误差满足业务化海浪预报要求,为保障船舶系泊安全,合理进行生产调度,提高码头装卸效率提供科学指导。     

合成风场在南海台风浪数值模拟中的研究

基于第三代海浪模式SWAN,利用Myers理论模型风场、CCMP风场以及两者的合成风场,分别作为台风驱动风场,对2003~2010年经过南海的15个台风浪过程进行数值模拟研究。将数值模拟结果与台风期间Jason-1卫星高度计观测资料进行比较,结果表明:Myers理论模型风场模式在台风中心附近波高较大时与实测值吻合较好,CCMP风场模式离台风中心较远处与实测值吻合较好。合成风场结合了Myers理论模型风场和CCMP风场各自的优点,比较符合南海的台风风场分布;合成风场模式的数值模拟结果与实测值吻合良好,能很好地适用于南海。     

两种海浪模式模拟结果的对比研究

利用合成风场驱动SWAN和WAVEWATCHⅢ这两种海浪模式,分别模拟了墨西哥湾海域和印度洋海域的海浪,并将两种海浪模式的模拟结果与波浪实测资料及Jason-1卫星高度计观测资料进行对比研究。研究结果表明:以CCMP风场为背景风场,合成Myers台风模型风场所得的合成风场能较好地模拟台风风场,但对于部分台风风场,模拟结果明显偏小。WW3对台风浪的模拟效果偏弱,SWAN模拟效果更好,与实测值更接近;对于大范围海域的海浪模拟,SWAN对涌浪传播的模拟耗散较大,模拟的波高和周期均偏小,而WW3模拟效果更好。

Recent progress on wave induced loading measurements in warships

Recent measurements of wave induced hull strain and flexure in RN warships are presented together with the derivation of the current design criteria for extreme hull girder bending loads. The history of the development of the shipboard instrumentation used is given and recent developments to improve the quality and ease of analysis of the data are described. An unexpectedly high transverse asymmetry in the longitudinal strains measured in destroyers is shown to be the result of a combination of vertical and lateral bending in oblique seas. Finally recent theoretical comparisons between the loading of Deep-Vee hulls and conventional UK rounded bilge hulls are presented which demonstrate the higher loading experienced by this type of hull form.

Impact of regulation on the performances of long-distance transport services: A comparison of the different approaches in Sweden and Norway

Despite the many socio-economic similarities between Sweden and Norway, differences in jurisdiction, organisation, cooperation, and financing of long-distance passenger train and coach services have led to the development of four distinctively different ways of serving the markets. This paper describes how the train and coach markets have developed in the two countries, with emphasis on regulatory and industrial structure and a couple of performance variables.Looking at passenger rail, both countries separated infrastructure from operation over a decade ago. However, while Norwegian rail is characterised by an almost monopoly supplier, rail services in Sweden are partly decentralised to the responsibility of county authorities and are widely subjected to competitive tendering. The rest of the network is about to be opened up for on-the-track competition. Swedish Rail (SJ) has spent the last decades consolidating its core business (passenger rail) and sold out its other businesses. In contrast, the Norwegian state rail (NSB) has expanded its business to become a major bus operator and property owner, with extensions also into the Swedish market.The coach industry was more recently deregulated in both countries. The Swedish coach market is dominated by privately owned companies operating services to and from Stockholm. In Norway, state-owned NSB is a major coach operator on medium distance routes, and is also the largest partner of Nor-Way Bussekspress which totally dominates long-distance coach services. Further, the Norwegian coach market is characterised by cross-ownership and cooperation which has enabled an extensive route network which covers most of Norway.We find distinct differences in achievements in the two modes and in the two countries. Swedish rail services have succeeded in winning market shares and in renewing and developing both infrastructure and service levels to a greater extent than the Norwegian model. On the other hand, the Norwegian coach market seems to be more developed and efficient compared to its Swedish counterpart.The paper concludes with a discussion on the possible links between the different approaches and the performance observed, with the aim to stimulate further and more detailed research on some important issues.
