摘要这项研究的目的是利用挪威气象研究所开发的一种新的后播来计算有效波高的100年返回值估计。这一区域后预报覆盖了东北大西洋，时间跨度为1958-2009年。返回值估计基于极值统计中常用的三种不同的平稳模型：广义极值(GEV)分布、r最大阶统计量(RLOS)的联合GeV分布和广义帕累托(GP)分布。在这里，研究了模型与其相应的置信度区间之间的定性差异。
AbstractThe objective of this study is to compute 100-yr return value estimates of significant wave height using a new hindcast developed by the Norwegian Meteorological Institute. This regional hindcast covers the northeast Atlantic and spans the period 1958–2009.The return value estimates are based upon three different stationary models commonly applied in extreme value statistics: the generalized extreme value (GEV) distribution, the joint GEV distribution for the r largest-order statistic (rLOS), and the generalized Pareto (GP) distribution. Here, the qualitative differences between the models and their corresponding confidence intervals are investigated.
