Statistical properties of geomagnetic measurements as possible precursors for magnetic storms
Andres R. R. Papa, Lilian P. Sosman
Records of geomagnetic measurements have been analyzed looking for evidences of possible precursors for magnetic storms. With this objective, the main magnetic storms in the period…
Changes in fractal properties of geomagnetic indexes as possible magnetic storms precursors
Vitor H. A. Dias, Jorge O. O. Franco, Andres R. R. Papa
Records of Dst, Kp and Sym-H indexes are analyzed looking for evidences of possible precursors for magnetic storms. To accomplish this task the main magnetic storms were located an…
Simulating geomagnetic reversals through 2D Ising systems
Jorge O. O. Franco, Vitor H. A. Dias, Andres R. R. Papa
In this work 2D Ising systems were used to simulate the reversals of the Earth's magnetic field. Each spin was supposed to be a ring current in the Earth dynamo and the magnetizati…
On the time distribution of reversals in Earth's magnetic field
Cosme F. Ponte-Neto, Andres R. R. Papa
This paper presents an analysis on the distribution of periods between consecutive reversals of the Earth's magnetic field. The analysis includes the randomness of polarities, whet…
