Variability of climatic characteristics оver the South-East Baltic coastal waters in the early XXI century
The study is focused on features of hydrometeorological conditions in the southeastern Baltic Sea and their trends assessment for 2005—2019 (climatic half period). The authors used the data from field observations of atmospheric pressure, wind direction and speed, and air temperature from the automatic hydrometeorological station located offshore, as well as the satellite data from the infrared and microwave (radar images) ranges to determine sea ice and sea surface temperature,...

On asymptotic expression for velocity field of atmosphere gas perturbed by 1D acoustic wave
The problem of 1D acoustic wave initiation by a rise of water masses is formulated as a boundary problem at half space . The atmosphere is modeled as a multi-layer gas with an exponential structure of density in each layer. The boundary conditions at determine the direction of propagation, by link between dynamic variables (pressure, density, and velocity) of the wave. It defines the dynamic projection operators on the subspaces of z-evolution for each layer. The universal formulas for the perturbation of atmospheric variables in an arbitrary layer are derived in frequency ...

Effects of storm events on the upper atmos-phere in the Baltic sea
... layer was 19 % during the storm. The increase in the amplitudes of ionospheric variations with periods of 6—20 min over the area of a meteorological storm was also revealed. The results of the numerical experiment on the disturbance of the upper atmosphere due to the observed variations in surface pressure also showed an increase in wave activity with periods of ~ 15 min and the formation of a large-scale disturbance at the heights of the thermosphere.

The Evolution, or Seasonal and Interannual Variability, of the Diurnal Variation of Hydrometeorological Fields in the Southern Baltic Sea
We present the results of an analysis of field observations of the air temperature Ta, the dew point Td (relative humidity f), the sea-level atmospheric pressure P0, and the wind speed W. The data were obtained by a Mini- KRAMS-4 hydrometeorological facility installed within Russia’s exclusive economic zone in the southeastern Baltic Sea on the LUKOIL-KMN (D6) offshore ice-resistant fixed platform and ...
