Four-dimensional analysis of the hydrophysical fields in the tropical Atlantic using a complete non-linear model of currents: Numerical simulation andin situ data treatment

This paper reports the results of a numerical modelling experiment on estimating the accuracy of four-dimensional analysis using the twins technique.In situ temperature and salinity data collected in the tropical Atlantic are treated using a special algorithm. Some features resulting from the disagreement between the hydrophysical fields at the time of assimilation are discussed.Translated by V. Puchkin.
