“…These values are 10-20 % lower in the nearshore regions (Suursaar and Kullas 2009a, b;Suursaar 2010). The most frequent wave heights are also about 20 % lower than the long-term average wave height Soomere 2008;Soomere et al 2012).…”

“…9.15). In terms of climate change, only data from upward-looking echo sounders at Almagrundet (1977, Broman et al 2006 and from a directional wave-rider at Darss Sill have been analysed (Soomere and Kurkina 2011;Soomere et al 2012). The data from the wave-rider in the northern Baltic Proper were discussed by Kahma et al (2003), Tuomi et al (2011).…”

“…A large proportion of the low waves (H s < 0.25 m) for most of the coastal visual observation sites (except for Vilsandi) (Zaitseva-Pärnaste et al 2009 resembles an analogous property of simulated distribution in semi-sheltered bays (Soomere 2005). The frequency of occurrence of waves with H s > 4 m is very low for all subbasins except the Bothnian Sea (Tuomi et al 2011) and waves with H s > 2 m may be considered extreme for semisheltered areas such as the Darss Sill (Soomere and Kurkina 2011;Soomere et al 2012). However, even sheltered bays may experience very strong waves during violent storms from unfavourable directions; for instance, H s > 4 m apparently occurred in the interior of Tallinn Bay on 15 November 2001 (Soomere 2005).…”

“…Most of the combinations of wave heights and periods roughly correspond to wave fields with a Pierson-Moskowitz (PM) spectrum (Soomere 2008;Soomere et al 2012). This indicates a large proportion of fully saturated seas in this region at wind speeds up to about 8 m s −1 .…”

This chapter describes observed changes in sea level and wind waves in the Baltic Sea basin over the past 200 years and the main climate drivers of this change. The datasets available for studying these are described in detail. Recent climate change and land uplift are causing changes in sea level. Relative sea level is falling by 8.2 mm year −1 in the Gulf of Bothnia and slightly rising in parts of the southern Baltic Sea. Absolute sea level (ASL) is rising by 1.3-1.8 mm year −1 , which is within the range of recent global estimates. The 30-year trends of

“…Although there were several studies focused on the modelling of wave field in this region (e.g. Jönsson et al 2003, Soomere and Raamet 2011, Soomere et al 2012, only in a few cases SWAN model was applied (Cieślikiewicz and Herman 2001, Reda and Paplińska 2002, Kriezi and Broman 2008.…”

Extreme bottom velocities induced by wind wave and currents in the Gulf of Gdańsk

et al. 2017

The principal goal of this study is to get some preliminary insights about the intensity of water movement generated by wind waves, and due to the currents in the bottom waters of Gulf of Gdańsk, during severe storms. The Gulf of Gdańsk is located in the southern Baltic Sea. This paper presents the results of analysis of wave and current-induced velocities during extreme wind conditions, which are determined based on long-term historical records. The bottom velocity fields originated from wind wave and wind currents, during analysed extreme wind events, are computed independently of each other. The long-term wind wave parameters for the Baltic Sea region are derived from the 44-year hindcast wave database generated in the framework of the project HIPOCAS funded by the European Union. The output from the numerical wave model WAM provides the boundary conditions for the model SWAN operating in high-resolution grid covering the area of the Gulf of Gdańsk. Wind current velocities are calculated with the M3D hydrodynamic model developed in the Institute of Oceanography of the University of Gdańsk based on the POM model. The three dimensional current fields together with trajectories of particle tracers spreading out of bottom boundary layer are modelled, and the calculated fields of bottom velocities are presented in the form of 2D maps. During northerly winds, causing in the Gulf of Gdańsk extreme waves and most significant wind-driven circulation, the wave-induced bottom velocities are greater than velocities due to currents. The current velocities in the bottom layer appeared to be smaller by an order of magnitude than the wave-induced bottom orbital velocities. Namely, during most severe northerly storms analysed, current bottom velocities ranged about 0.1-0.15 m/s, while the root mean square of wave-induced near-seabed velocities reached maximum values of up to 1.4 m/s in the southern part of Gulf of Gdańsk.
