A temporal sliding procedure for ocean wave variational data assimilation and its application

为波浪的顺序的性能变化数据吸收，我们建议了时间的重叠在被考虑的一个时间的滑动方法。这个方法的优点是优化过程的起始的波浪光谱被观察在后者和以前的时间修改。这个时间的滑动过程为边缘的区域是重要的，如此的著名计算机生产厂商他中国海，在吸收有效性的持续时间是 2-3 天的地方。实验在气旋 9403 的整个功课(俄罗斯人) 被执行。在气旋中心附近，波浪元素的最大的价值没由吸收改变大部分，因为极端价值被还没被优化的风精力输入决定。在在气旋中心外面的区域，这修正为风波浪生长特别是明显的。

For sequential performance of wave variational data assimilation, we proposed a temporal sliding method in which the temporal overlap is considered. The advantage of this method is that the initial wave spectrum of the optimization process is modified by the observations in latter and former times. This temporal sliding procedure is important for marginal region, such as the China seas, where the duration of assimilation effectiveness is 2-3 days. Experiments were performed in the whole course of Cyclone 9403 （Russ）. Around the cyclone center, the maximum value of wave elements did not change much by assimilation, because the extreme value was determined by wind energy input that was not yet optimized. In the area outside the cyclone center, this modification is evident especially for wind wave growth.
