The influence of different versions of the planetary boundary layer parameterization in the model of system “Wave – Atmosphere” on the quality of wind wave simulation is investigated. The system consisting of components: WAVEWATCH (wave) / WRF (atmosphere) adapted for the Baltic Sea is described. The schemes of the planetary boundary layer parameterization used in the WRF are considered. From all experiments are selected two cases with stormy conditions observed in 2014: from 11 to 20 August and from 4 to 10 October. The comparison is produced by root-mean-square error of significant wave height simulation calculated according to automated FMI buoys located in Northern Baltic Proper, Bothnian Sea, Bay of Bothnia, Gulf of Finland. The sensitivity of significant wave height reproduction to different ways to PBL is evaluated. The evolution of storm waves at each buoy point is considered. The selection of parameterization with less errors in wind wave simulation is justified.
