Advance in modes and skills on predicting mesoscale oceanographic processes in the key sea regions
Recently, the project of “Study on Modes and Skills on Predicting Mesoscale Oceanographic Processes in the Key Sea Regions” from China Academy society has acquired a good result in the Medium Term Assessment, in Tsingtao. Weiming Fan, the director of resource and environment bureau of CAS, Xu Chang, vice director of resource and environment bureau of CAS and Xiaobo Ren, the director of atmos-ocean department of CAS, have attended in this meeting. The all experts consider that this project is scientifical and rich-fruits has made a great headway.. The Medium Term Assessment reached an unanimously pass.
“Study on Modes and Skills on Predicting Mesoscale Oceanographic Processes in the Key Sea Regions ” is an important project, proposed by the Resource and Environment Bureau of CAS. And Prof.Dongxiao Wang is the chief scientist of this project. It mainly researchs the meso-scale oceanographic process and develops predicting models in north region of South China Sea.
Through several key methods, such as in-site survey, Sub-Surface Buoys Observation, Acoustic Detecting, Remote Sensing Interpretation, Theoric Analysis and Numerical Modeling, The project of “Study on Modes and Skills on Predicting Mesoscale Oceanographic Processes in the Key Sea Regions” reveals the time-spatial distribution characters and ACOUSTIC effect of the meso-scale vortex, front, cline, internal wave and so on, resolves the key scientific and technical problems on predicting and forecasting the meso-scale phenomenon in coastal regions of China Sea.
During the 2-years’ research, the organizer of this project has implemented a comprehensive ocean survey in the north region of South China Sea., and have distributed and taken back three groups of sub-surface buoys successfully. The meso-scale phenomenon characters of meso-scale vortex, internal wave, cline and so on, has been studied seriously, Meantime, they could provide the objective analytical products. The project, has completed the improvement and test of the ocean environment observing sub-surface buoy, has reconstructed ACOUSTIC field and developed ACOUSTIC high-speed forecasting model and algorithm, has finished the tentative design and work of 1/12 degree HYCOM meso-scale vortex model,and developed two internal wave model. It has gathered the comparison of Ensemble Optimize interpolation and 3D-var autograph data, built a sea surface remote sensing meso-scale information database and developed light information distraction and inversion method, and designed a data contribution and service platform scheme. The organizer of this project has already published 80 papers.
