Future Antarctic bed topography and its implications for ice sheet dynamics
Future Antarctic bed topography ice sheet dynamics
2015/1/6
The Antarctic bedrock is evolving as the solid Earth responds to the past and ongoing evolution of the ice sheet. A recently improved ice loading history suggests that the Antarctic Ice Sheet (AIS) ha...
Floating stones off El Hierro, Canary Islands: xenoliths of pre-island sedimentary origin in the early products of the October 2011 eruption
Floating stones off El Hierro Canary Islands xenoliths of pre-island sedimentary origin early products
2015/1/4
A submarine eruption started off the south coast of El Hierro, Canary Islands, on 10 October 2011 and continues at the time of this writing (February 2012). In the first days of the event, peculiar er...
New developments in the analysis of column-collapse pyroclastic density currents through numerical simulations of multiphase flows
column-collapse pyroclastic density currents numerical simulations of multiphase flows
2015/1/4
A granular multiphase model has been used to evaluate the action of differently sized particles on the dynamics of fountains and associated pyroclastic density currents. The model takes into account t...
The reconciliation of mantle chemistry with the structure of the mantle inferred from geophysics and dynamical modelling has been a long-standing problem. This paper reviews three main aspects. First,...
Remobilization of silicic intrusion by mafic magmas during the 2010 Eyjafjallajökull eruption
silicic intrusion mafic magmas 2010 Eyjafjallajokull eruption
2014/12/31
Injection of basaltic magmas into silicic crustal holding chambers and subsequent magma mingling or mixing is a process that has been recognised since the late seventies as resulting in explosive erup...
Influence of the Ringwoodite-Perovskite transition on mantle convection in spherical geometry as a function of Clapeyron slope and Rayleigh number
Ringwoodite-Perovskite transition mantle convection spherical geometry Clapeyron slope Rayleigh number
2014/12/31
We investigate the influence on mantle convection of the negative Clapeyron slope ringwoodite to perovskite and ferro-periclase mantle phase transition, which is correlated with the seismic discontinu...
The stochastic quantization method and its application to the numerical simulation of volcanic conduit dynamics under random conditions
stochastic quantization method application to the numerical simulation volcanic conduit dynamics random conditions
2014/12/31
Stochastic Quantization (SQ) is a method for the approximation of a continuous probability distribution with a discrete one. The proposal made in this paper is to apply this technique to reduce the nu...

Testing conceptual and physically based soil hydrology schemes against observations for the Amazon Basin
Testing conceptual physically based soil hydrology
2014/12/18
This study analyzes the performance of the two
soil hydrology schemes of the land surface model ORCHIDEE in estimating Amazonian hydrology and phenology for five major sub-basins (Xingu, Tapajó...
A mimetic, semi-implicit, forward-in-time, finite volume shallow water model: comparison of hexagonal–icosahedral and cubed-sphere grids
A mimetic semi-implicit forward-in-time
2014/12/18
A new algorithm is presented for the solution
of the shallow water equations on quasi-uniform spherical
grids. It combines a mimetic finite volume spatial discretization with a Crank–Nicolson ...
Evaluation of the new UKCA climate-composition model – Part 2: The Troposphere
UKCA climate-composition Troposphere
2014/12/18
In this paper, we present a description of the tropospheric chemistry component of the UK Chemistry and
Aerosols (UKCA) model which has been coupled to the Met
Office Hadley Centre’s HadGEM fa...
A fast input/output library for high-resolution climate models
high-resolution climate models input/output library
2014/12/18
We describe the design and implementation of climate fast input/output (CFIO), a fast input/output (I/O) library for high-resolution climate models.

Coupling a new turbulence parametrization to RegCM adds realistic stratocumulus clouds
turbulence parametrization RegCM adds realistic stratocumulus
2014/12/10
To model stratocumulus clouds in the regional climate model, RegCM4.1, the University of Washington (UW)
turbulence parametrization has been coupled to RegCM. We
describe improvements in RegCM’s coa...
Models of soil organic matter decomposition: the SOILR package, version 1.0
soil organic matter decomposition
2014/12/10
Soil organic matter decomposition is a very important process within the Earth system because it controls the
rates of mineralization of carbon and other biogeochemical
elements, determining their &...
