Ocean 4DVar Data Assimilation Research in the Northern South China Sea
摘要
Abstract
In order to study the four-Dimensional Variational assimilation (4DVar) in northern South China Sea marine numerical forecast,ocean data assimilation system is build based on the Region Ocean Model System (ROMS).The observed sea surface temperature and temperature and salinity profiles are assimilated,using the4DVar.The three 4DVar methods are tested and compared,which are I4DVar,4DPSAS and R4DVar.The 4DVar shows good performance,and the I4DVar method is more stable than 4DPSAS and R4DVar.The research result in this paper is foundation of the South China Sea ocean operational 4DVar assimilation and forecast system.关键词
