This paper analyzes artificial acoustical impact inside natural clouds, in particular inside the non-precipitated stratiform clouds, non-precipitating shallow cumulus clouds, and Cu-clouds with drizzle. Optimal power and frequency for acoustical impact were indicated based on properties of natural cloud, such as liquid water content, droplet concentrations, and the average diameter size of a droplet ensemble followed by lognormal or gamma size distributions in the presented consideration. The model is constructed to ensure collisions of neighboring droplets when they vibrate in acoustical field to merge with mass unification, but the process is designed with a minimum required level of acoustic power for comfort realization in practice. Vibration model of suspended droplets with typical size in cloud is analyzed. The optimized acoustic power is near 130 dB, and frequency f  50 – 100 Hz, and detailed characteristics are indicated for each cloud type depending on their parameters. Simple formulas and typical calculations for droplet amplitude are presented in terms of parameters of acoustical field as well as cloud characteristics. The first low-frequency acoustic experiments for clouds are performed and presented. The low-frequency method has shown a promising potential to be used for precipitation enhancement to tackle water shortage problem in the modern world.

The author has extended possibilities of axiomatic method for writing deductive theories in biology and anthropology and their parallel systematization by creating an algorithm consisting of 32 rules. The algorithm is based on the hypothesis that all words are deductible from each other and on the hypothesis that the properties of the living beings are periodically repeatable when they are arranged in a row. The hypotheses made it possible to find two periodic systems similar to D.I. Mendeleev’s system. These systems help to determine the order of axioms in a row of theories. The algorithm is supplemented by links of axioms that are similar in the non-living, living, and intelligent worlds with notions of symmetry. The work can raise the axiomatic method to a new level also in the area on unification of knowledge.

The paper еtheorizes the relationship between a redshift in the electromagnetic spectrum of space objects and their gravity and demonstrates it with computational experiments. Redshift, in this case, is a consequence of deceleration of the photons emitted from the surface of objects, which is caused by the gravity of these objects. The photon speed reduction due to the attraction of space gravitating object (GO) is defined as ΔC = C-C ‘, where C’ is a photon speed changed by the time the receiver records it. Then, at photon speed variation between a stationary source and a receiver, the redshift factor is determined as Z = (C-C ‘)/C’. Computational experiments have determined the gravitational redshift of the Earth, the Sun, a neutron star, and a quasar. The graph of the relationship between the redshift and the ratio of sizes to the mass of any space GOs washas been obtained. The findings indicate that the distance to space objects does not depend on the redshift of these objects.

The paper considers the features of the mutual influence caused by the ice cover of the Arctic waters and the meridional components of the atmospheric circulation in the Northern Hemisphere of Earth, which are manifested in the modern period. The identification of such features is an urgent problem of climatology, meteorology, oceanography, as well as the maritime transport industry.
The subject of this research is the statistical relationship between interannual changes in a number of characteristics of the Arctic ice cover and components of the atmospheric circulation. The features of the impact of external factors on them are also investigated.
The paper checks the adequacy of the hypothesis put forward that the significant factors of the interannual variability of the characteristics belonging to Arctic Air Outbreak that occur in the summer season in a number of regions of the Arctic include variations in the state of their ice cover caused by the combined effect of global warming and the decline of the average level of solar activity taking place in the current period.
To achieve this goal, there are considered the results of a retrospective analysis of changes in 1993–2019 concerning average daily values of the average thickness of the ice cover, its concentration, average temperature and salinity of the surface layer of the Arctic water areas, as well as air temperatures and meridional components of wind speed in various layers of the troposphere. The specified information has been obtained from the GLORYS, V12, NCEP / NCAR, and ERA - Interim electronic databases. The method of correlation analysis and statistical goodness-of-fit tests were used to assess the adequacy of the hypothesis under consideration.
Using the example of the Arctic waters located in the European, Siberian, Far Eastern and Pacific sectors of the Northern Hemisphere, the features of the mutual influence of changes in the state of their ice cover and meridional components of the atmospheric circulation in the summer season are revea
