According to the paleomagnetic analysis there are variations of Earth's magnetic field
connected with magnetic moment changing. These variations affect on the South Atlantic …

Field reversals are the most spectacular events in the geomagnetic history but remain little
understood. Here we explore the dipole behaviour in particularly long numerical dynamo …

We investigate the phenomenology of reversals predicted by a multiscale αω dynamo model
in which a hierarchical structure of length scales accounts for the nature of turbulent thermal …

The Earth's magnetic field is the sum of several contributions. These are internal ones, ie the
core field, also known as the main field, and the crustal or lithospheric field, and external …

Paleomagnetic results from Europe and North America show that the Lower Triassic is
characterized by mixed polarity (" Buntsandstein-Chugwater mixed polarity zone"), in …

The study of geomagnetism is, after geodesy, the oldest of the geophysical sciences and,
with the advent of plate tectonics, perhaps the most important. European mariners were …

The top of Earth's liquid outer core is nearly 2900 km beneath Earth's surface, so we will
never be able to observe it directly. This hot, dense, molten iron‐rich body is continuously in …

Geomagnetic intensity fluctuations provide important constraints on time-scales associated
with dynamical processes in the outer core. PADM2M is a reconstructed time series of the 0 …

Abstract The South Atlantic Anomaly (SAA) is an area of geomagnetic weakness that
represents the most significant anomaly in the present‐day field. Notwithstanding anomalies …
