摘要:
基于HYCOM海洋模式和集合最优插值(EnOI)同化方法,开发了一套西北太平洋及印度洋三维温盐流数值预报业务系统(IAPos),2016年5月开始进行业务试验,并对业务试验的结果与原有的三维温盐流数值预报系统(wylV2)进行对比检验,从检验结果看:在中国近海,IAPos系统的预报效果,较wylV2有非常显著的改善,但对不同预报变量、不同垂直层、不同区域也有一些差异。整体来说,IAPos系统的预报性能较好。
Based on the HYCOM ocean model and the Ensemble Optimal Interpolation (EnOI) assimilation method, a three-dimensional ocean numerical forecast operational system in the Northwest Pacific and Indian sea (IAPos) is established, and began to run operational test from May in 2016. The modeled results are contrasted to the former three-dimensional ocean model system (wylV2). The results show that the forecasting ability of IAPos system is better than that of wylV2 system in the China seas. There are some difference between different forecast variables and different vertical layers. In general, the forecast capability of the IAPos is better than that of the wylV2.
