Recent studies on the behavior of geomagnetic secular acceleration (SA) pulses have
provided a basis for understanding the dynamic processes in the Earth's core. This analysis …

地磁急变(jerk) 是起源于地球外核并在导电地幔过滤效应后在地球表面观测到的一种地磁现象,
其反映了地核内部某些动力学过程. Jerks 在空间范围上既可以是区域性的, 也可以是全球性的 …

摘要研究中国地区地磁急变(jerks) 和地磁长期加速度(secularacceleration, SA) 的响应关系,

In recent years, the evolution of the magnetic flux lobes in terms of location and intensity has
been attributed to paleosecular variation of the geomagnetic field, reflecting outer‐core fluid …

The Earth's surface magnetic field and its secular variation (SV) are composed of several
constituents, at sub-centennial (60–90 years) and inter-decadal (20–30 years) timescales, of …

Studying the relationship between geomagnetic jerks and the geomagnetic secular
acceleration (SA) in the China region is helpful for better understanding the regional …

Declination annual mean time series longer than 1 century provided by 24 geomagnetic
observatories worldwide, together with 5 Western European reconstructed declination series …

As a geomagnetic phenomenon, the geomagnetic jerk originates from the Earth's outer core,
which is observed on the Earth's surface after the filtering of the conductive mantle. It reflects …
