The Stability

Based on the simulation of a marine ecosystem dynamical model in the Bohai Sea, routine monitoring data are assimilated to study the initial field of pollution by using the adjoint method. In order to reduce variables that need to be optimized and make the simulation results more reasonable, an independent grid is selected every four grids both in longitude and latitude, and only the pollutant concentrations of these independent grids needed to be optimized while the other grids were calculated by interpolation method. Based on this method, the stability and reliability of this model were proved by a set of twin experiments. Therefore, this model could be applied in real experiment to simulate the initial field of the total nitrogen (totalN) in May, 2009. Moreover, the distribution of totalN in any time step could be calculated by this model, and the monthly mean distribution in May in the Bohai Sea could be obtained.

The Bohai Sea

Based on the simulation of a marine ecosystem dynamical model in the Bohai Sea, pseudo observations are assimilated to study the initial field of chemical oxygen demand (COD) by using the adjoint method. The three-dimension Princeton Ocean Model (POM) is used to calculate the ambient physical velocities, and only four tidal components (M2, S2, K1 and O1) are taken into account. First a prescribed initial distribution of COD is given. Run the forward model and we can pickup some pseudo observations. Then a set of twin experiments were designed to validate the inversion capability of this ecosystem dynamical model. It was discovered that no matter which form the initial field was, the adjoint method could reduce the misfit between inversion results and observations significantly, indicating that this model was stable and reliable. Therefore, this model could be applied in real experiment to simulate the initial field of COD in the Bohai Sea in future.
