Travel-time tomography in shallow water: Experimental demonstration at an ultrasonic scale [PDF]

, 2011
International audienceAcoustic tomography in a shallow ultrasonic waveguide is demonstrated at the laboratory scale between two source-receiver arrays. At a 1/1 000 scale, the waveguide represents a 1.1-km-long, 52- m-deep ocean acoustic channel in the ...

Planetary magnetic fields [PDF]

, 1983
As a consequence of the smallness of the electronic fine structure constant, the characteristic time scale for the free diffusive decay of a magnetic field in a planetary core is much less than the age of the Solar System, but the characteristic time ...

Exploring the impact of CMIP5 model biases on the simulation of North Atlantic decadal variability [PDF]

, 2015
Instrumental observations, palaeo-proxies, and climate models suggest significant decadal variability within the North Atlantic subpolar gyre (NASPG).

Experimental investigation into localized instabilities of mixed Rayleigh-Bénard-Poiseuille convection [PDF]

, 2017
The stability of the Rayleigh-Bénard-Poiseuille flow in a channel with large transverse aspect ratio (ratio of width to vertical channel height) is studied experimentally. The onset of thermal convection in the form of ‘transverse rolls' (rolls with axes

Large-scale features of Pliocene climate: results from the Pliocene Model Intercomparison Project [PDF]

, 2013
Climate and environments of the mid-Pliocene warm period (3.264 to 3.025 Ma) have been extensively studied. Whilst numerical models have shed light on the nature of climate at the time, uncertainties in their predictions have not been systematically ...

A numerical study of the longitudinal thermoconvective rolls in a mixed convection flow in a horizontal channel with a free surface

, 2012
This paper presents a numerical study of three-dimensional laminar mixed convection within a liquid flowing on a horizontal channel heated uniformly from below. The upper surface is free and assumed to be flat.
