On the external forcing of global eruptive activity in the past 300 years
J-L. Le Mouël, D. Gibert, V. Courtillot +11
The decryption of the temporal sequence of volcanic eruptions is a key step in better anticipating future events. Volcanic activity is the result of a complex interaction between i…
Is the Earth's magnetic field a constant ? a legacy of Poisson
J-L. Le Mouël, F. Lopes, V. Courtillot +2
In the report he submitted to the Académie des Sciences, Poisson imagined a set of concentric spheres at the origin of the Earth's magnetic field. It may come as a surprise to many…
On distributions law of planetary rotations and revolutions as a function of aphelia, following Lagrange's formulation
F. Lopes, V. Courtillot, D. Gibert +2
Earth rotation is determined by polar motion (PM) and length of day (lod). The excitation sources of PM are torques linked to fluid circulations ("geophysical excitations"), and th…
On the Slow Drift of Solstices: Milankovic Cycles and Mean Global Temperature
F. Lopes, V. Courtillot, D. Gibert +1
The Earth's revolution is modified by changes in inclination of its rotation axis. Despite the fact that the gravity field is central, the Earth's trajectory is not closed and the…
On the Nature and Origin of Atmospheric Annual and Semi-annual Oscillations
V. Courtillot, J-L. Le Mouël, F. Lopes +1
This paper proposes a joint analysis of variations of global sea-level pressure and of Earth's rotation (RP), expressed as the coordinates of the rotation pole and length of day. S…
On the annual and semi-annual components of variations in extent of Arctic and Antarctic sea-ice
F. Lopes, V. Courtillot, D. Gibert +1
The time series of northern hemisphere (NHSI) and southern hemisphere (SHSI) sea-ice extent are submitted to singular spectral analysis (SSA). The components are analyzed with Lapl…
