Lévy noise versus Gaussian-noise-induced transitions in the Ghil–Sellers energy balance model [PDF]
Nonlinear Processes in Geophysics, 2022 We study the impact of applying stochastic forcing to the Ghil–Sellers energy balance climate model in the form of a fluctuating solar irradiance. Through numerical simulations, we explore the noise-induced transitions between the competing warm and ...

Geodesy in Japan: legends and highlights
Earth, Planets and Space, 2020 Here, I review modern history of geodesy and geodynamics in Japan, highlighting a few episodes during the last two centuries. The review starts with the first measurement of the meridional arc length in Japan by Tadataka Ino (1745–1818) early in the ...

Genesis of the Planet Earth [PDF]
International Letters of Chemistry, Physics and Astronomy, 2015 This article is based on the theory of vortex gravitation and physical abnormalities of the Earth - slowing its rotation. Defined orbital acceleration, weight, approach to the Sun and the age of our planet. Offered to justify the creation of planetary material in the center of the Earth torsion, and not as the accumulation of cosmic dust and meteorites
