Increase in Storm Activity in the Kara Sea from 1979 to 2019: Numerical Simulation Data

Doklady Earth Sciences - Wind wave modeling (WAVEWATCH III model) is used to analyze the storm activity in the Kara Sea for the period from 1979 to 2019. The NCEP/CFSR/CFSv2 reanalysis data used as...     

Wave Climate in the Caspian Sea Based on Wave Hindcast

The results of wind wave hindcast for the Caspian Sea for the period of 1979–2017 are presented. The WAVEWATCHIII wave model and wind forcing from the NCEP/CFSR reanalysis are used. The modeling is performed on the unstructured grid with the spacing to 1 km in the coastal zone. Mean and extreme values of wave height, length, and period are provided. It is shown that the maximum height of waves of 3% probability of exceedance is 11.7 m. The interannual variability of wave parameters is analyzed. No unambiguous trend towards increase or decrease in the storm activity was revealed over the hindcasting period.

Tidal discrete-wave motions and continental drift

The concept of special running waves of deformation that provide the wave mass transfer of solids, liquids, and gases is considered. These unidirectional motions called discrete-wave give rise to the lateral displacement of bodies. The discrete-wave motions arise under the effect of tidal forces of the Moon and the Sun on the Earth and induce the lateral displacements of geospheres, which include the atmosphere, oceanic currents, and the lithosphere. The tidal discrete-wave motions are real and permanently acting planetary events that provide mass transfer and accumulation of energy. They are crucial in the lateral displacements of the lithosphere, its particular blocks, and in the continental drift. Such motions cannot be ignored in the consideration of global tectonics.
