On the Winter Wave Climate of the Western Black Sea: The Changes During the Last 115 Years

摘要

We present a study of the winter wave climate of the Western Black Sea with a focus on the annual maximums and the mean seasonal wave heights. We did a numerical simulation of the wave parameters in the Black Sea by the wave model SWAN for a period of 110 years. The input wind fields are from the atmospheric reanalysis ERA-CLIM. We also performed a hindcast for the period 1980-2015 using winds from the CFSR reanalysis. Extended winter (December-March) was studied. We also studied the characteristics of the pressure gradients in a larger region attempting to quantify this way the interaction of Mediterranean lows with blocking highs. No significant long term changes were found for any of the characteristics of the mean and extreme wave climate.
