Young, Paul J. ; Butler, Amy H. ; Calvo Fernández, Natalia ; Haimberger, Leopold ; Kushner, Paul J. ; Marsh, Daniel R. ; Randel, William J. ; Rosenlof, Karen H. | American Geophysical Union | 2013-01-27We present a comparison of temperature trends using different satellite and radiosonde observations and climate (GCM) and chemistry-climate model (CCM) outputs, focusing on the role of photochemical ozone depletion in the Antarctic lower stratos[...]texto impreso
Analyses of the effective elastic thickness of the Martian lithosphere have been previously used to calculate surface heat flow on Mars at different places and times. In this work, I use elevation differences in a putative Late Hesperian shoreli[...]texto impreso
Jiménez, P. A. ; Dudhia, J. ; González Rouco, J. Fidel ; Montávez, J. P. ; García Bustamante, E. ; Navarro, J. ; Vilà-Guerau de Arellano, J. ; Múñoz Roldán, A. | American Geophysical Union | 2013-07-27The performance of the Weather Research and Forecasting (WRF) model to reproduce the surface wind circulations over complex terrain is examined. The atmospheric evolution is simulated using two versions of the WRF model during an over 13year per[...]texto impreso
Arrillaga Mitxelena, Jon Ander ; Jiménez, Pedro ; Vilá Guerau de Arellano, Jordi ; Jiménez, María A. ; Román Cascón, Carlos ; Sastre Marugán, Mariano ; Yagüe Anguis, Carlos | American Geophysical Union | 2020-02-27Sea breeze (SB) frontal passages, the relevant factors influencing their formation and their interaction with local turbulence, are analyzed. To proceed, numerical simulations from the Weather Research and Forecasting (WRF) model are compared wi[...]texto impreso
Barriopedro Cepero, David ; Gomez Escolar, M. ; Fueglistaler, S. ; Calvo Fernández, Natalia | American Geophysical Union | 2012-11-22Stratospheric Sudden Warmings (SSWs) strongly affect the polar stratosphere during winter months mainly in the Northern Hemisphere. The intraseasonal distribution and type of SSWs for the 1958-1979 and 1979-2002 periods in ERA-40 and NCEP-NCAR r[...]texto impreso
Evans, N. M. ; Smerdon, J. E. ; Kaplan, A. ; Tolwinski-Ward, S. E. ; González Rouco, J. Fidel | American Geophysical Union | 2014-12Climate field reconstructions (CFRs) of the global annual surface air temperature (SAT) field and associated global area-weighted mean annual temperature (GMAT) are derived in a collection of pseudoproxy experiments for the past millennium. Pseu[...]texto impreso
Torre, Laura de la ; Garcial, Rolando R. ; Barriopedro Cepero, David ; Chandran, Amal | American Geophysical Union | 2012-02-25Major stratospheric sudden warmings (SSW) occurring during Northern Hemisphere winter were identified in four runs of the Whole Atmosphere Community Climate Model (WACCM). Their characteristics are compared to those found by other authors using [...]texto impreso

MacDougall, Andrew H. ; Beltrami, Hugo ; González Rouco, J. Fidel ; Stevens, M. Bruce ; Bourlon, Evelise | American Geophysical Union | 2010-06-18Heat fluxes in the continental subsurface were estimated from general circulation model (GCM) simulations of the climate of the last millennium and compared to those obtained from subsurface geothermal data. Since GCMs have bottom boundary condi[...]texto impreso
Ribera, P. ; Peña Ortiz, C. ; García Herrera, Ricardo ; Gallego, D. ; Gimeno, L. ; Hernández Martín, Emiliano | American Geophysical Union | 2004-09-23The quasi-biennial oscillation (QBO) signal in stratospheric zonal and meridional wind, temperature, and geopotential height fields is analyzed based on the use of the National Centers for Environmental Prediction (NCEP) reanalysis (1958-2001). [...]texto impreso
Gutiérrez Alonso, Gabriel ; Fernández Suárez, Javier ; Jeffries, Teresa E. ; Johnston, Stephen T. | American Geophysical Union | 2011U?Pb (zircon) crystallization ages of 52 late?Variscan granitoid intrusions from NW Iberia (19 from new data, 33 from previous studies) constrain the lithospheric evolution of this realm of the Variscan belt of Western Europe and allow assessmen[...]texto impreso
Barriopedro Cepero, David ; García Herrera, Ricardo ; Lionello, Piero ; Pino, Cosimo | American Geophysical Union | 2010-07-01This study explores the long-term frequency variability of high-surge events (HSEs) in the North Adriatic, the so-called acqua alta, which, particularly during autumn, cause flooding of the historical city center of Venice. The period 1948-2008,[...]texto impreso
The dynamical connection between Northern Hemisphere blocking events and the variability of the stratospheric polar vortex strength is studied. The analysis is based on the composite time evolution of the energy of baroclinic planetary waves dur[...]texto impreso
Díez Fernández, Rubén ; Jiménez Díaz, Alberto ; Arenas Martín, Ricardo ; Pereira, M. Francisco ; Fernández Suárez, Javier | American Geophysical Union | 2019-01The Calzadilla Ophiolite is an ensemble of mafic and ultramafic rocks that represents the transition between lower crust and upper mantle of a Cadomian (peri?Gondwanan) fore arc. Mapping and structural analysis of the ophiolite demonstrates that[...]texto impreso
Stevens, M. Bruce ; Smerdon, Jason E. ; González Rouco, J. Fidel ; Stieglitz, Marc ; Beltrami, Hugo | American Geophysical Union | 2007-01-18[1] A one-dimensional soil model is used to estimate the influence of the position of the bottom boundary condition on heat storage calculations in land-surface components of General Circulation Models (GCMs). It is shown that shallow boundary c[...]
