Perturbazioni geomagnetiche, aurorali, ionosferiche e dei raggi cosmici : interdipendenze e relazioni con l'attività solare

Annals of Geophysics, 1966
Existence of interplanetary magnetic fields other than<br />the geomagnetic field is now well established. They travel as frozen-in<br />fields inside the solar plasma clouds: magnetic fields on the Sun are then<br />discussed ...

The physics of space weather/solar-terrestrial physics (STP): what we know now and what the current and future challenges are [PDF]

Nonlinear Processes in Geophysics, 2020
Major geomagnetic storms are caused by unusually intense solar wind southward magnetic fields that impinge upon the Earth's magnetosphere (Dungey, 1961). How can we predict the occurrence of future interplanetary events?

EULERIAN DECORRELATION OF FLUCTUATIONS IN THE INTERPLANETARY MAGNETIC FIELD [PDF]

The Astrophysical Journal, 2010
A method is devised for estimating the two-time correlation function and the associated Eulerian decorrelation timescale in turbulence. With the assumptions of a single decorrelation time and a frozen-in flow approximation for the single-point analysis, the method compares two-point correlation measurements with single-point correlation measurements at

The Structure and Origin of Switchbacks: Parker Solar Probe Observations

The Astrophysical Journal, 2023
Switchbacks are rapid magnetic field reversals that last from seconds to hours. Current Parker Solar Probe (PSP) observations pose many open questions in regard to the nature of switchbacks.

From the Sun to the Earth: The 13 May 2005 Coronal Mass Ejection [PDF]

, 2010
We report the results of a multi-instrument, multi-technique, coordinated study of the solar eruptive event of 13 May 2005. We discuss the resultant Earth-directed (halo) coronal mass ejection (CME), and the effects on the terrestrial space environment ...

A superposed epoch analysis of auroral evolution during substorms: Local time of onset region [PDF]

, 2010
peer reviewedPrevious workers have shown that the magnetic local time (MLT) of substorm onset depends on the prevailing east-west component of the interplanetary magnetic field (IMF).
