Name of the project:

Nonlinear hydrophysics with applications to natural disasters in the Far Eastern region.

Goals of project:

Studying the physics of nonlinear processes in the hydro- and geosphere with applications to hazardous (catastrophic) phenomena in the Far East region.

Project objective:

Developing a theory of nonlinear wave processes in the development of geospheric disasters and linking it to accumulated experimental data;
Studying the statistics of waves on the sea surface. Analyzing abnormally high outliers. Developing models of the formation of killer waves in the settings of deep and shallow waters and their subsequent verification using collected experimental data;
Studying the nature of infrasonic disturbances created by typhoons during their movement from the moment of their formation until complete dissipation;
Developing a technology for monitoring catastrophic storms for the purpose of minimization of their influence on the environment;
Developing a methodology for the assessment of the main parameters of tsunamis relying on crust deformation disturbances with their remote monitoring;
Researching microseisms of the «voice of the sea» while fine-tuning the methodology of angular position measurement of the zones where they originate;
An experimental, theoretical research and modeling of the laws of the formation and development of abnormal internal marine waves. Experimental research of undular bores on the shelf of the Sea of Japan and the verification of their models. A theoretical and experimental solution of the reverse problem of determining the parameters characterizing the hydrophysical background of shallow water: quadratic nonlinearity, dispersion and phase velocity of linear internal waves. Verifying the methodology over experimental data;
Creating computational atlases of baroclinic Rossby waves and internal waves of the Far Eastern region.
