“…This mechanism redistributes the ionosphere chemical constituents which can be distinguished up to different ionosphere heights and from large horizontal distances of the TC meridian (Guha et al, 2016). Individual noninteracting neutral particles can reach up to different ionosphere heights: oxygen ≈ 52 km, hydrogen ≈ 208 km, and helium ≈ 831 km due to different directional speed VT = (2kT/m) 1/2 .The heating of the stratosphere and the formation of a jet can occur because of the self-organization of nonlinear acoustic waves propagating upward (Aburjania et al, 2013), (Rudenko and Sapozhnikov, 2004). Oscillations of a vertically stratified dissipative atmosphere is reviewed in (Dmitrienko and Rudenko, 2016).…”

Abstract. The data analysis of the on-board instruments set of the Cosmos-1809 and IKB-1300 satellites is presented for the following events. Continuous sequence of tropical cyclones (TCs) after the Mounts Pinatubo and Hudson eruptions in 1991. Sequences of 3 super-typhoons in the Western Pacific in November 1990. Sequences of 5 hurricanes in the Atlantic Ocean in September 1981. It is shown that the effects of the several interacting TCs impact on the ionosphere differ from those of single TCs. The distribution of electron fluctuations and density, VLF-ELF oscillations, and other plasma parameters of the upper ionosphere varies at different stages of development of tropical disturbances. Models of TCs interaction that change the parameters of the ionosphere are proposed. An important role is played by acoustic oscillations generated in TCs. The strongest volcanic eruptions in the twentieth century threw a significant amount of aerosols into the stratosphere. It is discussed how stratosphere changes for interacting TCs and perturbations after volcanic eruptions apparently cause a redistribution of infrasound along the TCs track which can lead to the formation of new TCs.

Self-organization is a property of dissipative nonlinear processes that are governed by a global driving force and a local positive feedback mechanism, which creates regular geometric and/or temporal patterns, and decreases the entropy locally, in contrast to random processes. Here we investigate for the first time a comprehensive number of (17) self-organization processes that operate in planetary physics, solar physics, stellar physics, galactic physics, and cosmology. Self-organizing systems create spontaneous "order out of randomness", during the evolution from an initially disordered system to an ordered quasi-stationary system, mostly by quasi-periodic limit-cycle dynamics, but also by harmonic (mechanical or gyromagnetic) resonances. The global driving force can be due to gravity, electromagnetic forces, mechanical forces (e.g., rotation or differential rotation), thermal pressure, or acceleration of nonthermal particles, while the positive feedback mechanism is often an instability, such as the magneto-rotational (Balbus-Hawley) instability, the convective (Rayleigh-Bénard) instability, turbulence, vortex attraction, magnetic reconnection, plasma condensation, or a loss-cone instability. Physical models of astrophysical self-organization processes require hydrodynamic, magneto-hydrodynamic (MHD), plasma, or N-body simulations. Analytical formulations of self-organizing systems generally involve coupled differential equations with limit-cycle solutions of the Lotka-Volterra or Hopf-bifurcation type.
