Geomagnetism: Theories of since 1900
A definitive history of geomagnetism is yet to be written, but brief accounts have appeared in various publications. The story up to 1940 has been summarized (Chapman and Bartels, pp. 898-936). Perhaps the most complete account is by David R. Barraclough (pp. 584-592). Brief accounts have also been given by Stuart Malin (in Jacobs, ed., Geomagnetism, 1: 1-50), and others (Multhauf and Good, pp....
متن کاملGrand challenges in geomagnetism and paleomagnetism
Geomagnetism and paleomagnetism is a broad sub-discipline of the Earth Sciences. I present the Grand Challenges from the perspective of a paleomagnetist and rock magnetist, hence I feel more comfortable with the paleomagnetic side of this short article than the geomagnetic side. Nevertheless, exciting things are happening in geomagnetism and the future is bright for both paleomagnetists and geo...
متن کاملGeomagnetism and the Emission - Line Corona
This paper summarizes the results of an extensive investigation of the relation between Kp and the intensity of the emission-line corona. We consider the coronal intensity in the northern and the southern solar hemispheres separately, and find that the intensity in the hemisphere on the same side of the solar equator as the earth shows the closer relation to Kp. We discuss the identification of...
متن کاملGeomagnetism during solar cycle 23: Characteristics
On the basis of more than 48 years of morphological analysis of yearly and monthly values of the sunspot number, the aa index, the solar wind speed and interplanetary magnetic field, we point out the particularities of geomagnetic activity during the period 1996-2009. We especially investigate the last cycle 23 and the long minimum which followed it. During this period, the lowest values of the...
