Transport mechanism and influential factors of chloride ion in two different stages to atmospheric transport and concrete Transport were explored and an improvedmulti-factor model for surface chloride concentration in concrete structure Exposed to Marine atmosphere Zone was developed . firstly , The main influential factors onsurface chloride Concentration were investigated , and , influential laws of various Factors, including Marine environmental Conditions, concrete material Properties Then exposure time , and on surface Chloride concentration were explored . taking into consideration this Influences of, various important factors such as distance from theSea,wind speed , Water -to-binder ratio, Binder types and exposure time , Improved multi-factor model for surface chloride concentration of concrete structure Exposed To          marine atmosphere Zone was developed based on Marine Field data of multiple Locations including European,north American, South American and Asian data and Two-level multiple Nonlinear regression analysis . Finally , The accuracy and applicability of the Proposed model were demonstrated by comparing with

based on the global Ocean - sea ice coupling numerical mode , studied the trans-Atlantic circulation of sea-table driving field with different time and spatial resolution (Atlantic meridional overturningcirculation , Amoc and sea surface temperature ( seasurface Temperature , SST ) Impersonation effect . The results of the Sensitivity numerical experiment show that The difference between, and the time and spatial resolution of the Sea-table driving field will not only affect SST simulation , and can significantly affect amoc intensity simulation . compared to high time resolution Sea table driving field , reduction in time and space resolution results in Amoc simulate intensity decrease and SST elevated . average driving field driver amoc ratio 6 h Resolution driving field driven control experiment reduction 6.7Sv , lowers 34%; Same as 6hdivide Resolution , Rough space resolutions atmospheric driving field simulations Amoc lower than space resolution experiment 1.4Sv , the reduces the 7%. to the ocean upper flow field and the sea surface heat flux Further analysis indicates that , Low-time and spatial-resolution sea surface wind field weakening is caused by Amocweakens and SST The main reason for the elevation .

Ocean Mode and data assimilation method for numerical simulation of ocean three-dimensional warm salt flow , In mesoscale numerical prediction and re-analysis apply , and required support conditions , describes progress and issues at home and abroad . the describes a wide-range resolution, "" Numerical simulation of high-resolution oceanic three-dimensional temperature and salinity flow in degree and even secondary mesoscale vortices the issues under study ,brief description provide match the need for a high-performance computer simulation platform for . Preliminary discussion on issues restricting the rapid development of the study .

This article uses ocean satellite to observe sea surface temperature ( SST ) and sea surface height exception (SLA ) data , on SOA first ocean researchInvestigate Earth system mode fio- ESM ( the "a Institute ofoceanographyearthsystem Model version 1 0) China Sea The Ocean mode component is set to adjust the Kalman filter (eakf) Assimilation , The contrasts the general circulation of the atmosphere , Humidity and cloud cover for ocean data Assimilation response , influence of ocean assimilation on the simulation deviation of tropical precipitation . results show : Ocean data assimilation effectively improves sea table simulation of temperature and upper ocean thermal content , °s ~ 30° N Latitude Band annual average SST The absolute difference of is reduced by 60% . assimilation of atmospheric modulessimulation of the equatorial side of the wind has significantly improved , The ascending airflow is enhanced in the tropical regions north of the equator, minus the in the tropics south of the equator weak , The dynamic structure of the tropical precipitation simulation is more reasonable , the water vapor and cloud cover distributions are also more realistic . Spatial distribution of annual average rainfall in the tropics and intensity improved after assimilation , A significant reduction in the peak annual average precipitation in the south of the equator , precipitation deviations are significantly reduced , after assimilation , °s~ 30° N reduce the average mean precipitation in the latitude band by 35% .
