This article emphasises that one of the conditions for the formation of extreme inflow events from the North into the Baltic Sea is the long-time impact of same-type atmospheric processes on the water surface. There is a need to consider the intensity and the duration of one-direction atmospheric processes. The authors focus on the features and types of large-scale atmospheric circulation over
the North-East Atlantic, which determined the regional atmospheric processes over the Baltic Sea during the formation of a large inflow. The article analyses the inflows of December 22, 1975 — January 14, 1976, and the inflow of January 16—222003, as well as baric topography (500hPa) and daily synoptic maps.

This article offers the results of regular (weekly) monitoring of the coast of the Vistula Lagoon in the area of the village of Pribrezhny (the Kaliningrad region) throughout the year. The steady profile measurements of the beach width, photographing, coast description, the calculation of changes in the relative level of the Vistula Lagoon, and the analysis of the wind regime over the observation period made it possible to reveal the coast dynamics, assess the stability of the beach and coastal slope condition, as well as the influence of the
main regime-forming factor — the wind.

This article offers a computer simulation for incompressible stratified fluid based on Euler’s equations. The ocean and the atmosphere above it are considered as an integral continuous environment. At the water-air surface, the density changes abruptly from ρ = ρwater = 1000 kg/m3 for water to ρ = ρair = 1.2 kg/m3 for air. The solution to model equations is generalised. The mathematical mechanism
of equation solving suggests automatic smoothing of density in the area of wave breaking and formation of a thin fluid layer with an intermediate density.

This article offers an analysis of a series of maximum values of annual levels in 1950-2009 and historical maximums of storm onsets in Kaliningrad. The authors calculated the linear trend equation and identified the duration of onset cycles. The article offers a forecast for 2016.
