Geomagnetic reversals at the edge of regularity
Breno Raphaldini, Everton S. Medeiros, David Ciro +2
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…

Topography-induced persistence of atmospheric patterns
David Ciro, Breno Raphaldini, Carlos M. Raupp
Atmospheric blockings are persistent large-scale climate patterns with duration between days and weeks. In principle, blockings might involve a large number of modes interacting no…

Evidence for crisis-induced intermittency during geomagnetic superchron transitions
Breno Raphaldini, David Ciro, Everton S. Medeiros +2
The geomagnetic field's dipole undergoes polarity reversals in irregular time intervals. Particularly long periods (of the order of yrs) without reversals, named superchrons,…
