Local Wind Regime Induced by Giant Linear Dunes: Comparison of ERA5-Land Reanalysis with Surface Measurements
Cyril Gadal, Pauline Delorme, Clément Narteau +4
Emergence and growth of sand dunes results from the dynamic interaction between topography, wind flow and sediment transport. While feedbacks between these variables are well studi…
Coexistence of two dune growth mechanisms in a landscape-scale experiment
Ping Lü, Clément Narteau, Zhibao Dong +5
In landscape-scale experiments at the edge of the Gobi desert, we show that various dune types develop simultaneously under natural wind conditions. Using 4 years of high-resolutio…
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…
Triskels and Symmetries of Mean Global Sea-Level Pressure
F. Lopes, V. Courtillot, J-L. Le Mouël
The evolution of mean sea-level atmospheric pressure since 1850 is analyzed using singular spectrum analysis. Maps of the main components (the trends) reveal striking symmetries of…
On two formulations of polar motion and identification of its sources
F. Lopes, V. Courtillot, JL. Le Mouël +1
Differences in interpretation may arise from differences in formulation of the equations of celestial mechanics. This paper focuses on the Liouville system of differential equation…
Rapid Variations of Earth's Core Magnetic Field
V. Lesur, N. Gillet, M. D. Hammer +1
Evidence of fast variations in the Earth's core field are seen both in magnetic observatory and satellite records. We present here how they have been identified at the Earth's surf…
