简介：整体最佳的插值(EnOI)被用于与吸收沿着轨道海水平异例(TSLA)的能力为系统(ROMS)建模的地区性的海洋。这个系统与华南海(SCS)的一个解决旋涡的系统被测试。背景错误从一变季节被导出在SCS以内说明季节的可变性的整体。有250km本地化半径的第五顺序的本地化功能被选择减少采样错误的否定效果。数据吸收系统从2004年1月被测试到2006年12月。结果证明根意味着海水平异例的方形的偏差(RMSD)从10.57～6.70厘米减少了，它代表错误的36.6%减小。为在内的温度的数据吸收还原剂错误上面800m并且为在内的咸度上面200m，尽管错误在更深的深度稍微降级。表面水流在对在数据吸收以后的表面流浪者的轨道的更好的同意。海水平的变化在吸收TSLA以后以强壮、弱的变化区域的振幅和位置显著地改善。当考虑温度和咸度的改进时，有年龄错误(年龄)的结果比没有年龄错误(NoAGE)更好表现。而且，在高分辨率在北SCS为极其强壮的可变性推想模型被调查。结果证明在高分辨率模型的海水平的强壮的可变性被极其强壮的自台湾东面的菲律宾海流向日本的暖流侵入引起。因此，吸收TSLA以便更好与高分辨率模型一起模仿SCS是必要的，这被表明。

简介：在这篇论文，统计远离台风和非带的上层的急流有关在暴雨之间的关联被分析。在200hPa的急流是的结果表演常常SW(90.2%)在在哪个暴雨发生的时期期间。在权利的降雨区谎言饲养喷气斧子的区域。当暴风雨加强时，喷气趋于更强壮并且变得非带。与MM4模型一起，数字模拟和诊断在8月19日为台风No.9711(Winnie)被执行到20。1997。远暴雨是紧关联词到喷气和低级台风马槽。喷气的分叉地与v部件有关。上面的水平能在底层引起关於气压变化的风集中。这是低级台风马槽的表格和暴风雨的力量的结果。由规模分析，有在在在300-hPa下面的喷气后面的正确入口区域的横向的反的循环铺平的中间的规模的一个分支，这被发现，它对维护很重要并且暴雨加强。反的循环的这个分支相对喷气的非带的特征的加强。从中央规模分叉地的域和非带的风地，我们知道更强壮的对称在喷气的二个方面由横向的循环引起了。降雨喷气有的非带的特征的反馈和加强导致暴雨的是有利的加强的积极反馈机制。
