Abstract EN
This paper presents an algorithm for the estimation of open boundary conditions (OBCs) which force tides in the interior region by an adjoint data assimilation approach.
Assuming that OBCs are position dependent, OBCs can be approximated by linear interpolation among values at certain independent points (IPs).
Twin experiments are performed to examine the sensitivity of the model to the IP distribution and interpolation radius.
It is proved that the prescribed OBCs can be well recovered with appropriate number of IP and interpolation radius.
In the Bohai Sea model domain with horizontal resolution of 10’×10’, the appropriate number of IP is 3 and the interpolation radius is 60′.
In the practical experiment, the M2 constituent in the Bohai Sea is simulated by assimilating the T/P data and tidal gauge data.
The mean absolute errors in amplitude and phase are 5.0 cm and 5.7°, respectively, and the cochart obtained shows the character of M2 constituent in the Bohai Sea.
