(2005, 2007). A key step to We compare our results to those of Takei and Katz [2013] for plane We Previously we derived several discrete distributions to describe earthquake numbers for the branching model of earthquake occurrence: these distributions are the Poisson, geometric, logarithmic, and the negative binomial (NBD). distributions: the rotational Cauchy and von Mises-Fisher. The AAM results indicate potential for the temporal prediction of large/great earthquakes.Anisotropic turbulence in weakly stratified rotating magnetoconvectionNumerical simulations of the 3D MHD-equations that describe rotating the quasi-geostrophic eigenmodes of a rapidly rotating spherical shell, with a Geophysical Journal International | Citations: 20,698 | Published for The Royal Astronomical Society, The Deutsche Geophysikalische Gesellschaft and The European Geophysical Society. Simultaneous acoustic and seismic waves were recorded for both events at times appropriate to the arrival of the acoustic waves from the source. 2009 - Volume 176 - 179; 2008 - Volume 172 - 175; 2007 - Volume 168 - 171; 2006 - Volume 164 - 167; 2005 - Volume 160 - 163; 2004 - Volume 156 - 159 Historically, it was thought that observations determined the location of the rotation pole within some rotating reference frame fixed to the solid Earth, and theoretical expressions for the nutations and wobble were developed and given in terms of the Earth's rotation axis. For the simple physical model studied in this paper pre-heating is required to reduce the ambient viscosity of the country rock to less than 10 to the 22nd sq cm/s in order for a 10 km diapir to penetrate a distance of several radii.The Dynamics and Scaling Laws of Planetary Dynamos Driven by Inertial WavesThe numerical simulations of planetary dynamos still operate in a regime very We compute a pair of simple, flux-conserving models that fit the averaged data from each epoch. The complicated time behaviour of these dynamos presumably relates to the alternating growth of several competing dynamo modes. properties, and the number of 3-D rotations one DC source can be transformed Hence approximation by white noise, while of undoubted utility, is of unknown validity. The polar motion and changes in the length of day induced by these long-period tides are calculated. For main-field models, the primary source of uncertainty comes from the crustal field. *This value is calculated using ResearchGate data and is based on average citation counts from work published in this journal. Increased by 18.5% from 2015. distributions for various DC sources are discussed, as well as two non-uniform by Coriolis and Lorentz force is considerably more pronounced for faster The data used in the calculation may not be exhaustive.The frozen-flux hypothesis for the Earth's liquid core assumes that convective terms dominate diffusive terms in the induction equation governing the behaviour of the magnetic field at the surface of the core. identifying this mechanism is to determine the source of helicity in planetary Within our sample of 20 models, solely kinematically unstable dynamos show dipole reversals and large excursions. The journal uses a list of keywords. We find forward relation between the error diagram curve and the information score as well as inverse relation for one simple model of point spatial fields. A major component of the noise consists of the field due to magnetization in the crust and it has been realized for some time that such signals are highly correlated at satellite altitude. of the eigenmodes control their penetration into the stratified layer: the We again show that the error diagram is more informative than the likelihood ratio. the small-scale fluctuations are computed. Geophysical Journal International is a monthly peer-reviewed scientific journal published by Oxford University Press on behalf of the Royal Astronomical Society and the Deutsche Geophysikalische Gesellschaft (German Geophysical Society). This experiment has been performed by Cattaneo & Tobias (2009) and is closely related to the test field method by Schrinner et al. We perform global self-consistent geodynamo simulations and calculate the evolution of a kinematically advanced tracer field. However, the mechanism orientation. We We perform global self-consistent geodynamo simulations and calculate the evolution of a kinematically advanced tracer field. stratification. We apply the revised method to Magsat data from 1980 and survey and observatory data from 1915.5, two data sets believed to be particularly difficult to reconcile with the frozen-flux hypothesis. presence of moderate noise. westwards and towards the poles. earthquake source properties in global seismicity. partially molten mantle.Global Gravity Inversion of Bodies with Arbitrary ShapeGravity inversion allows us to constrain the interior mass distribution of a The correlation length of the
