МОДЕЛИРОВАНИЕ ШТОРМОВОГО ВОЛНЕНИЯ В БАРЕНЦЕВОМ МОРЕ

Abstract

The implementation of spectral wave model SWAN for the Barents Sea, including the Northern part of the Atlantic Ocean was presented. Computations were performed by using special unstructured mesh, which has spatial resolution in the Atlantic Ocean is 1°, in the Barents – 0,5°. The wind forcing data from reanalysis NCER-CFSR and from mesoscale models WRF-ARW and COSMO-CLM used. The simulation results quality was provided by comparing modeled significant wave with satellite data. Numerical calculations are performed for January 2010, because in this time there was a series of storms. For compare we also used the results of AARI-PD2 wave model which implemented in the AARI. It is shown that both models are generally adequately reproduce the wind regime at points of stations. Synoptic variability of wind speed simulated well, but local features simulated much worse. The values of correlation coefficient (average 0.7) is significant and evidence that the overall variability simulated well, but they do not assure good quality of modeling wind waves. Wind wave modeling results revealed that in the current configuration, forcing COSMO-CLM and WRF produces a results close to the NOАА and NCEP-CFSR.
