Study finds Earth’s magnetic field ‘simpler than we thought’
Earth’s magnetic simpler than we thought
2017/7/24
Scientists have identified patterns in the Earth’s magnetic field that evolve on the order of 1,000 years, providing new insight into how the field works and adding a measure of predictability to chan...

Evolution of magnetotelluric,total magnetic field,and VLF field parameters in Central Italy:relations to local seismic activity
Magnetotelluroc tectonomagnetism VLF waves
2015/9/28
Magnetotelluric data were collected at Collemeluccio (41.72°N, 14.37°E) in Central Italy from summer 1991 to spring 1998. Analyzed by means of tensor decomposition on the geoelectric potential and rob...
Analysis of a Permo-Triassic polarity transition in different absolute reconstructions of Pangaea,considering a model with features of the present Earth magnetic field
Permo-Triassic Pangaea absolute reconstruction Earth magnetic field polarity transition
2015/9/2
The main objective of this paper is to show that the distribution of transitional palaeomagnetic data recorded at 250 Ma are in agreement with simulated data that depend on the sampling site, using a ...
Post-processing scheme for modelling the lithospheric magnetic field
Satellite magnetic data the lithospheric magnetic field model of satellite orbit tracking satellite data noise disturbance in the magnetic field the scaling factor
2015/1/5
We investigated how the noise in satellite magnetic data affects magnetic lithospheric field models derived from these data in the special case where this noise is correlated along satellite orbit tra...
Earth's magnetic field older than we thought（图）
Earth's magnetic field the planet's core the ancient field
2010/3/26
Earth's magnetic field, which shields us from the Sun's deadly rays, emerged from the planet's core even earlier in Earth's history than we previously thought. While this field, 3.45 billion years ago...
A probabilistic approach to heterogeneity in space plasmas:the case of magnetic field intensity in solar wind
probabilistic approach heterogeneity space plasmas magnetic field intensity
2009/10/30
Since the early 90s it was shown that Probability Distribution Functions (PDFs) of small scale differences (fluctuations) of several quantities in space plasmas display significant departures from Gau...

Advection diffusion large scale magnetic field accretion disks
2009/10/30
Activity of the nuclei of galaxies and stellar mass systems involving disk accretion to black holes is thought to be due to (1) a small-scale turbulent magnetic field in the disk (due to the magneto-r...

The Cosmic Ray Asymptotic Directions for Station Oulu in the Magnetic Field of the Tsyganenko 1989 Model
cosmic rays magnetospheric magnetic field asymptotic directions geomagnetic disturbance level
2009/6/10
Using the magnetospheric field model developed by Tsyganenko (1989) the asymptotic directions
were calculated for cosmic ray particles entering the top of the atmosphere at Oulu (65.°06N, 25.°47E).Th...
