Toward the Selection of Control Parameters in Models of the Purposeful Weather and Climate Modification

A unified methodology for planning and implementation of weather and climate modification (geoengineering) can be apparently developed based on the ideas and methods of geophysical cybernetics in which the climate system and its processes represent a control object and the role of the controlling subsystem is given to the appropriate social structures and, in particular, to operators having the necessary resources. This problem can be solved based on the sensitivity theory of dynamical systems. In this paper, as an example, we study the impact of the main parameters that control the development of baroclinic instability in the atmosphere on the growth rate of unstable waves. Analytical expressions for the absolute and relative sensitivity coefficients are obtained, which allows estimating the model response to the control parameters and, therefore, drawing a conclusion about the hypothetical ability to control the large-scale wave dynamics in the atmosphere and ocean. Selecting the baroclinic instability as a subject of this study is due to the significant role of this physical mechanism in the formation of the general circulation of the atmosphere and ocean, and, consequently, the Earth's climate.
