Abstract | Data assimilation (DA) is an essential issue for operational prediction centers, where a com-puter code is applied to simulate physical phenomena by solving differential equations. The pro-cedure to determine the best initial condition combining data from observation and previousforecasting (background) is carried out by a data assimilation method. The Kalman filter (KF) isa technique for data assimilation, but it is computationally expensive. An approach to reduce thecomputational effort for DA is to emulate the KF by a neural network. The multi-layer perceptronneural network (MLP-NN) is employed to emulate the Kalman in a 2D ocean circulation model,and algorithmic complexity to KF and NN is presented. A shallow-water system models the oceandynamics. Synthetic measurements are used for evaluating the MLP-NN for the data assimilationprocess. Here, a parallel version for the DA procedure by the neural network is described andtested, showing the performance improvement for a parallel version of the NN-DA. |
