A preliminary dynamic view of the circulation of Jupiter's atmosphere
Geofisica pura e applicata - Tập 110 - Trang 2108-2129 - 1973
The problem of the gross nature of the Jovian atmospheric circulation is examined from the viewpoint of the following previous findings of the writer and others. 1) The equatorial acceleration cannot be accounted for by axisymmetric motions. 2) The departures from symmetry in a rotating system having an equatorial acceleration must impart angular momentum selectively to those particles moving towa...... hiện toàn bộ
Estimation of Deeper Structure at the Soultz Hot Dry Rock Field by Means of Reflection Method Using 3C AE as Wave Source
Geofisica pura e applicata - Tập 150 - Trang 661-676 - 1997
—We investigate the deep subsurface structure below the artificial reservoir at the Soultz Hot Dry Rock (HDR) site in France by a reflection method which uses acoustic emission (AE) as a wave source. In this method, we can detect reflected waves by examining the linearity of a three-dimensional hodogram. Additionally for imaging a deep subsurface structure, we employ a three-dimensional inversion ...... hiện toàn bộ
Magnetotelluric Power Line Noise Removal Using Temporally Varying Sinusoidal Subtraction of the Grid Utility Frequency
Geofisica pura e applicata - Tập 180 - Trang 3303-3317 - 2023
The magnetotelluric method relies on variations of natural electromagnetic fields, which in the vicinity of human settlements are persistently distorted by anthropogenic electromagnetic noise. A large source of noise to the magnetotelluric response is caused by the harmonic oscillations of the power network utility frequency centered on 50/60 Hz along with the associated higher harmonics. Removing...... hiện toàn bộ
Attenuation Characteristics of Body-Waves for the Bilaspur Region of Himachal Lesser Himalaya
Geofisica pura e applicata - Tập 173 - Trang 447-462 - 2015
The attenuation characteristics around Bilaspur region of the Himachal Lesser Himalaya have been estimated adopting extended-coda-normalization method, and using a data set of 41 local events (0.5 < M
L ≤ 2.9) that occurred in the region from May 2013 to March 2014. The frequency-dependent relations governing the quality factors of P-waves (Q

The fractal geometry of flow paths in natural fractures in rock and the approach to percolation
Geofisica pura e applicata - Tập 131 Số 1-2 - Trang 111-138 - 1989
On the stability properties of the nongeostrophic disturbances in a barotropic zonal current
Geofisica pura e applicata - Tập 96 - Trang 193-204 - 1972
The stability properties of the nongeostrophic disturbances are studied in a barotropic zonal current. The growth rate of the nongeostrophic disturbances is increased and the instability is generally shifted towards shorter wavelengths. Even in the structure of the nongeostrophic disturbances large differences are found as compared to geostrophic disturbances.

Magnetic Anomaly Characteristics Analysis of a Finite-Length Submarine Cable
Geofisica pura e applicata - Tập 178 - Trang 4529-4547 - 2021
Submarine cables are a typical weak magnetic target. Studying the magnetic anomaly principle of these cables and establishing their magnetic anomaly model are the bases of realizing magnetic detection, location, and recognition. The magnetic anomaly model of a 2D, infinite-length, horizontal cylinder is traditional and typical. However, when the cable is laid on a polygonal line under the constrai...... hiện toàn bộ
