摘要

Abstract

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.
