Often in nature the temporal distribution of inhomogeneous stochastic point processes can be modeled as a realization of renewal Poisson processes with a variable rate. Here we investigate one of the classical examples, namely, the temporal distribution of polarity reversals of the geomagnetic field. In spite of the commonly used underlying hypothesis, we show that this process strongly departs from a Poisson statistics, the origin of this failure stemming from the presence of temporal…

Statistical analysis of magnetic field reversals in laboratory dynamo and in paleomagnetic measurements

Statistical properties of the temporal distribution of polarity reversals of the geomagnetic field are commonly assumed to be a realization of a renewal Poisson process with a variable rate. However,

Inferring basic parameters of the geodynamo from sequences of polarity reversals

The asymmetric time dependence and various statistical properties of polarity reversals of the earth's magnetic field are utilized to infer some of the most essential parameters of the geodynamo;

The geodynamo as a random walker: A view on reversal statistics

[1] The sequence of durations of the geomagnetic polarity intervals is often described in terms of a nonhomogenous Poisson process with time-dependent reversal rate, reflecting the nonstationarity of

Geomagnetic reversals at the edge of regularity

Geomagnetic field reversals remain as one of the most intriguing problems in geophysics and are regarded as chaotic processes resulting from a dynamo mechanism. In this article, we use the polarity

Statistical Study of Magnetic Field Reversals in Geodynamo Models and Paleomagnetic Data

The most striking features in the temporal evolution of the Earth's dipolar magnetic field are polarity reversals and excursions. Several hundred polarity switches have been documented for the last

Are geomagnetic field reversals controlled by turbulence within the Earth's core?

We consider geomagnetic field reversal sequences from the last 160 Ma, and find the inter‐reversal times to be well fit by a lognormal distribution. Such a distribution could arise from

A model for the geomagnetic field reversal rate and constraints on the heat flux variations at the core-mantle boundary

Data of geomagnetic reversal rates are investigated and it is shown that the transition towards periods where reversals do not occur for tens of million years can be described by a second-order phase transition that is interpreted to be driven by variations of the heat flux at the core-mantle boundary (CMB).

Geomagnetic reversals and the stochastic exit problem

We consider a dynamical system consisting of a fundamental mode (amplitude x, nonlinearly stable) and one stable periodic overtone, coupled by multiplicative noise. The problem emerges from attempts

Asymmetric polarity reversals, bimodal field distribution, and coherence resonance in a spherically symmetric mean-field dynamo model.

Using a mean-field dynamo model with a spherically symmetric helical turbulence parameter alpha, the basic features of geomagnetic polarity reversals are shown to be generic consequences of the dynamo action in the vicinity of exceptional points of the spectrum.

Geomagnetic dipole strength and reversal rate over the past two million years

It is shown that, at least during this period, the time-averaged field was higher during periods without reversals but the amplitude of the short-term oscillations remained the same, and few intervals of very low intensity are expected during periods with a strong average dipole moment, whereas more excursions and reversals areexpected during periods of weak field intensity.
