Galactic Cosmic Rays - Clouds Effect and Bifurcation Model of the Earth Global Climate. Part 1. Theory

TL;DR

This paper develops a theoretical model linking galactic cosmic rays to Earth's cloud cover and climate bifurcations, highlighting the role of aerosol effects and magnetic field variations in climate dynamics.

Contribution

It introduces a bifurcation-based climate model incorporating cosmic rays and aerosol effects, providing a new theoretical framework for Earth's climate behavior.

Findings

Climate energy-balance described by a bifurcation equation.

Two key parameters: insolation and cosmic ray intensity.

Hierarchical model construction based on structural invariance.

Abstract

Based on theoretical and experimental consideration of the first (the Twomey effect) and second indirect aerosol effects the quasianalytic description of physical connection between the galactic cosmic rays intensity and the Earth's cloud cover is obtained. It is shown that the basic equation of the Earth's climate energy-balance model is described by the bifurcation equation (with respect to the temperature of the Earth's surface) in the form of assembly-type catastrophe with the two governing parameters defining the variations of insolation and Earth's magnetic field (or the galactic cosmic rays intensity in the atmosphere), respectively. The principle of hierarchical climatic models construction, which consists in the structural invariance of balance equations of these models evolving on different time scales, is described.
