Figure 1: Equatorial and meridional cross-sections of the axial component of the vorticity, ω z. Figure 2: Sheet plumes observed in experiment and simulation. By observing the plume pattern as a movie ...

A new analysis of computer simulations of Earth’s magnetic field suggests that its behavior was different early in Earth’s history, resulting in greater stability and fewer reversals of the magnetic ...

The Earth's magnetic field is generated by the complex interplay of convective flows in its liquid outer core, a process commonly referred to as the geodynamo. The dynamics of this magnetic field are ...

How does the Earth generate its magnetic field? While the basic mechanisms seem to be understood, many details remain unresolved. A team of researchers has introduced a simulation method that promises ...

Researchers are using the Blue Waters supercomputer at NCSA to better understand geomagnetic variations and their underlying mechanisms, so that better forecasting models can be developed. Deep in the ...

The Earth has a shell-like structure. It is divided into a core (inner and outer core), a mantle (lower and upper mantle, separated by a transition zone), and the earth's crust. The Earth’s magnetic ...
