Wave Climate of the Caspian Sea, Input Wind Data for Hydrodynamic Modeling, and Some Calculation Results

Abstract

The main stage of a modern approach to calculating the wave climate includes the creation of a sea state database based on hydrodynamic modeling. The input data for retrospective calculations are wind information available in the global hydrometeorological data reanalysis. This reanalysis, especially when reproducing the extreme statistics of the wave mode, should be adjusted in light of the regional characteristics of atmospheric processes. The specifics of any waters require a priori adaptation of hydrodynamic models to specific conditions, the results of which are checked by comparing model calculations with field observation data. The calculation results for the hydrodynamic model are summarized using a set of probabilistic models of different classes.
