Investigation of the westward drift of the earth’s main geomagnetic field based on the spatial distribution of secular variation derived from IGRF-14 [PDF]

E3S Web of Conferences
Westward drift of the Earth's magnetic field is an important manifestation of geomagnetic secular variation and provides information on fluid dynamics within the outer core.

WMM2020模型与我国局部区域航测地磁场数据差异分析

Dizhen xuebao
利用我国东西部两个区域的无人机实测航磁数据，分析其与WMM2020模型数据的偏差。对地磁场数据的北向分量、东向分量和垂直分量的差异分析结果显示：WMM2020模型数据与我国东部浙江省余姚区域地磁场数据的北向分量及垂直分量的差异较小，而与西部地区陕西省渭水区域地磁场数据的北向分量及垂直分量的差异较大；这两个区域内的模型数据与航磁数据的东向分量基本吻合，差异均很小。另外，研究还显示，渭水区域实测数据与WMM2020模型数据间偏差小于其与WMM2025模型间的偏差，而余姚区域的情况恰恰相反。

Neural network prediction of geomagnetic activity: a method using local Hölder exponents [PDF]

, 2002
Local scaling and singularity properties of solar wind and geomagnetic time series were analysed using Hölder exponents . It was shown that in analysed cases due to the multifractality of fluctuations, α changes from point to point.

THE METHOD TO SOLVE DRIFT IN MAIN GEOMAGNETIC FIELD

Proceedings of the Mongolian Academy of Sciences, 2016
The method to solve the velocity of drift in MGF is written in this paper. This method is based on the dynamo theory for geomagnetic field. The velocity of drift in the main geomagnetic field is also solved from the condition that the power variation of ...

Statistical relationships between variations of the geomagnetic field, auroral electrojet, and geomagnetically induced currents

Solar-Terrestrial Physics, 2019
Using observations from the IMAGE magnetic observatories and the station for recording geomagnetically induced currents (GIC) in the electric transmission line in 2015, we examine relationships between geomagnetic field and GIC variations.
