** The most important results**

- The obtaining of exact weak and strong solutions of the hydrodynamics equations, problems of the hydrodynamic stability and predictability on the base of the hydrodynamics equations, and also the turbulent diffusion theory of the chemically active and passive pollutions. The start of the works in this direction was set in my M.Sc. thesis in the Moscow Institute of Physics and Technology (https://mipt.ru/english/) in 1974. In my PhD thesis, [1-4] (IAP RAS, 1979), in my Doctor of Science thesis [5-7, 9-26] (ISR RAS, 1992), and in more recent papers [27-34; 39-41; 43; 46; 47; 49; 50; 52; 54; 57-59; 63; 69; 74-81; 86-93; 99, 100,107].

Thus, as a result in [107] the exact solution of main turbulence problem is obtained for the most complex compressible case/

- Various aspects of which are related to the hydrodynamics instability and exact solutions of the hydrodynamics equations were considered. Applications of the results obtained are in the field of geophysical hydrodynamics. Significant part of the works are devoted to the turbulent diffusion theory, modeling of the pollution transfer [7; 9; 10; 11; 13; 14; 16-18; 21-23; 25; 27-29; 31-34], and also to the investigation of the turbulent viscosity [20]. The papers [41; 50; 52; 84] have application in relation to the observed effects of swirling flows not only in tornado but also in the cardio-vascular system (CVS) that is very important for CVS normal functioning (see [48; 64; 65; 70-72]). Some results found also applications in the investigation of biophysical systems [35-38] and in the medicine of sleep (somnology) [51].
- I paper [9] the base for synergetic a new model of self-organization is proposed for a systems where in addition to the bimolecular chemical reactions also a transfer by the random non-Gaussian turbulent velocity field is realized. The model is alternative to the known synergetic Brusselator model (proposed by Ilya Prigogine) to autocatalytic trimolecular diffusion – control reactions. It has wider applicability with respect to it since application of the model [9] is not limited by the ban of the Hanusse theorem, e.g., for the kinetic equations with quadratic non-linearity corresponding to the most widely spread bimolecular processes.
- In the papers [6; 26; 74], we get conditions of parametric excitation of the internal gravity waves (IGW) in the stably stratified medium. It is found in [6; 26; 74] that in the region of the frequency parametric resonance of a linear oscillator with periodic in time frequency (Mathew equation), it takes place the symmetry breaking that is character for the for the phase transitions of the second kind. In [6; 26; 30; 74], we consider also application aspects related with the possibility of the IGW analysis as precursors in ionosphere of the strong earthquakes and tsunami. There is an opportunity of application of the theory developed in [6; 26; 74] to the new problem of the time crystals (F. Wilczek, 2013- arXiv:1308.5949; G.E. Volovik, JETP Lett., 2013).
- In papers [12; 15; 19] equations of dynamics of three-dimensional point vortex dipoles (extremely small ring vortices) known as the Roberts-Chefranov equations are inferred that are applicable to the description of the blow-like processes of vorticity increasing in the turbulent boundary layer. In [24] (advancing the method from [19]), we show that for the vortices collapse modeling the observed processes of the large-scale atmospheric vortices merging, significant role plays not the vortices size but their symmetry type. In [76], the theory from [19] is advanced for the case of the bounded fluid layer in relation to the modeling of the hydrodynamic mechanism of formation of the colloid and plasma-dust crystals.
- Papers [39; 46; 49; 75; 80] state conditions of the dissipative-centrifugal instability defining a mechanism of the observed violation of the cyclone-anticyclone symmetry and generally spontaneous breaking of the chiral symmetry in any model (physical, chemical, biological), that can be characterized by a linear oscillator in a rotational reference frame in the presence of the linear, with respect to velocity, friction.
- Papers [54; 57; 69; 83; 104] state an exact solution of the equations of the point vortices dynamics on a rotating sphere that can successfully model the interaction of the observed global vortex centers of action in the atmosphere that defines weather and climate anomalies in Europe and America.
