This article summarizes the related progress and issues about the oceanic 3-D temperature,salinity and current numerical simulation,including ocean model,data assimilation,the applications in the mesoscale numerical forecast and reanalysis,as well as the required supporting conditions.The related scientific issues in the wide range,mesoscale and submesoscale high-resolution ocean 3-D temperature,salinity and current numerical simula-tion are pointed out.The necessity of the developments of the oceanic in situ observations,such as the Argo pro-files,and the remote observations,like the satellite altimetry data,as well as the supporting conditions,such as the high-performance computer simulation platform,is briefly explained.From these,the related issues which constrain our high-speed progress of the mesoscale numerical simulation are preliminarily discussed.
