摘要
为了得到山东沿海台风浪的重现期波高分布场,以Jelesnianski-Ⅱ模型构建的风场作为模式驱动,利用SWAN模式建立了山东及其附近海域的台风浪数值模型。通过对典型台风过程"麦莎"和"梅花"的数值计算,将模拟的有效波高与观测数据作了对比分析,验证了模型在计算海域的适用性;基于建立的模型,对1960-2012年期间发生于山东沿海的50场台风进行模拟。选取计算海域10个点的模拟所得波高序列,寻求复合极值分布拟合最优的分布型式,根据所得分布进行重现期波高的统计分析;最终绘制计算海域50年一遇和100年一遇的台风浪波高分布图,为山东沿海的防灾减灾和海洋结构设计提供参考依据。
A SWAN wave model, which is driven by Jelesnianski-Ⅱ wind field model, is established to get the return period of typhoon wave height distribution map in Shandong coastal area. The typical typhoon processes ＂Masta＂ and ＂Muifa＂ are simulated and verified based on observation data. Based on the established model, 50 typhoons in Shangdong coastal area between 1960 and 2012 are simulated. The fitting curves in 10 points with four kinds of compound extreme value are selected from the simulated wave height sequences. The chosen distribution is adopted to do statistical analysis of wave heights. The wave height distribution map with the return period of 50 year and 100 year are draw out separately. The map can be used as reference for disaster prevention and reduction and marine structure design in Shandong coastal area.
