Wind wave climate of the baltic sea following the results of modelling by swan // The 11th Baltic Sea Science Congress ‘Living along gradients: past, present, future’, ABSTRACTS, June 12 – 16, 2017, pp. 368. — Baltic Sea Science Congress 2017, Rostock, June 12 – 16, 2017 Rostock, Germany, 2017. — P. 249–249. The long-term simulated wind wave data for 1979−2015, time period of the Baltic Sea were used to examine the properties of wind wave climate. The wave parameters were calculated using the SWAN spectral wave model with a regular mesh (0.05o). NCEP/CFSR (∼0.3o) input wind forcing was used. The simulated data were compared with instrumental data of the Sweden buoys (SMHI) and statistical errors were estimated. As input wind fields the NCEP/CFSR reanalysis was used. The results of numerical simulations were compared with the results of numerical modelling, based on other unstructured mesh with spatial resolution from 250 m to 10 km and on other input wind fields (NCEP/NACR). It was revealed, that for the Baltic Sea simulations have less significant errors with regular mesh and with data of NCEP/CFSR reanalysis. The simulated maximum significant wave heights, periods and the quantity of storm situations were calculated. The wind wave climate of the Baltic Sea has very instable character with its typical (10−12 years) time intervals of the increase and of the attenuation of the wind wave intensity. [ DOI ]
