The Hidden Link Between Earth’s Magnetic Field and Climate

By Kilifarska N.A., Bakmutov V.G. and Melnyk G.V.

The Hidden Link Between Earth’s Magnetic Field and Climate offers a new framework of understanding and interpretation for both well-known and less known relations between different geophysical and meteorological variables which can improve the quality of climate modeling. The book reviews the most current research on both current and paleo data to introduce a causal chain of interactions between the geomagnetic field, energetic particles which bombard the Earth’s atmosphere, ozone and humidity near the tropopause, and surface temperature.

The impacts of these complicated interactions is not uniformly distributed over the globe, thus contributing to our understanding of regional differences in climatic changes and the asymmetrical ozone distribution over the globe.

• Covers the newly discovered autocatalytic cycle for ozone production in the lower stratosphere, providing a better understanding of the heterogeneous distribution of ozone globally
• Outlines a mechanism for the lower stratospheric ozone influence on the temperature and humidity of the upper troposphere
• Provides a single resource on research in energetic particles’ modulation by heterogeneous geomagnetic fields, mechanisms of the influence of particles on the atmospheric ozone, and the influence of ozone on climate

Chapter 1

Geomagnetic field—Origin, spatial-temporal structure, and variability

Abstract

This chapter provides introductory information about Earth's magnetic field, necessary for understanding the following chapters of this book. The structure and methods for data collection of contemporary geomagnetic field are briefly described. More attention is paid to the methods for accurate determination of the intensity, and the precise dating of the ancient geomagnetic field. The chapter offers information about some widely used concepts like secular variations, westward drift of a nondipole part of geomagnetic field, geomagnetic reversals, and the origin of Earth's magnetic field. The secular variations during the 20th century are analysed in more detail. The reader will also find the most recent state of knowledge regarding the field generation and factors determining its external and internal variability. Finally, useful information about the recently available empirical models of geomagnetic field is
