A parallel version of the NEMO complex ocean circulation model has been implemented for the Black Sea basin; the results of circulation numerical modeling with a high spatial resolution are presented. Analysis of the spatial variability is performed for the reconstructed hydrophysical fields in 2005–2008. The resulting simulated spatial variability characteristics of the sea surface temperature are compared with available satellite observational data. 相似文献

This paper considers the main steps in improving the methods for calculating the ocean (sea) dynamics on the basis of observational
data on sea-water temperature and salinity. The results of diagnostic and adaptation calculations for the near-equatorial
area of the West Atlantic in the area of the Lomonosov countercurrent formation are presented. We consider the problem of
the complex use of measurements of temperature, salinity, and current velocity in the POLYMODE polygons with their assimilation
into the model using a Kalman filter. The results of calculations of the coordinated fields with the mechanism of geostrophic
adaptation and using asynchronous measurements obtained by the Razrezy program are given. We discuss further modifications
of the assimilation algorithms for hydrological observation data in models of sea dynamics and the principles of adaptation
of hydrophysical fields that made it possible to reconstruct the climate fields of the Black Sea and to reproduce the basin
dynamics for 23 years. 相似文献

We realize the algorithm of adaptive statistics of forecasting errors for the assimilation of the climatic fields of temperature
and salinity in the σ-coordinate model of the dynamics of the Black Sea. The principal relations of this algorithm and its
simplified version based on the Kalman filter are presented. The distinctive features of realization of the algorithm specified
by the model are discussed. We also present the results of comparison of the hydrophysical fields of the Black Sea reconstructed
according to the algorithm of adaptive statistics and a simplified scheme of assimilation of the climatic data. It is shown
that the dependence of sources in the transport equations (heat and salt diffusion) on the four-dimensional variances of forecasting
errors and threedimensional measurement errors enables one to reconstruct the mutually adapted climatic parameters of the
sea more exactly. 相似文献
