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
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[...]texto impreso
Stevens, M. Bruce ; González Rouco, J. Fidel ; Beltrami, Hugo | American Geophysical Union | 2008-02-05General circulation models (GCMs) are currently able to provide physically consistent simulations of millennial climate variability in which estimations of external forcing factors are incorporated as boundary conditions. Climate reconstruction [...]texto impreso
Lucio Eceiza, Etor E. ; González Rouco, J. Fidel ; Navarro, Jorge ; Beltrami, Hugo | Amer meteorological soc | 2018-01A quality control (QC) process has been developed and implemented on an observational database of surface wind speed and direction in northeastern North America. The database combines data from 526 land stations and buoys spread across eastern C[...]texto impreso
Lucio Eceiza, Etor E. ; González Rouco, J. Fidel ; Navarro, Jorge ; Beltrami, Hugo ; Conte, Jorge | American Meteorological Society | 2018-01A quality control (QC) process has been developed and applied to an observational database of surface wind speed and wind direction in northeastern North America. The database combines data from three datasets of different initial quality, inclu[...]texto impreso
MacDougall, Andrew H. ; González Rouco, J. Fidel ; Stevens, M. Bruce ; Beltrami, Hugo | American Geophysical Union | 2008-07-04Shallow bottom boundary conditions (BBCs) in the soil components of general circulation models (GCMs) impose artificial limits on subsurface heat storage. To assess this problem we estimate the subsurface heat content from two future climate sim[...]texto impreso
González Rouco, J. Fidel ; Beltrami, Hugo ; Zorita, E. ; von Storch, H. | American Geophysical Union | 2006-01-10A heat-conduction forward model driven by ground surface temperature from three 1000-year climate simulations with the state-of-the-art ECHO-g model has been used to simulate underground temperature perturbation profiles. An inversion approach h[...]texto impreso
Beltrami, Hugo ; Bourlon, Evelise ; Kellman, Lisa ; González Rouco, J. Fidel | American Geophysical Union | 2006-03-30Variations in the Earth's surface energy balance are recorded in the subsurface as perturbations of the steady state thermal field. Here we invert 558 temperature-depth profiles in the Northern Hemisphere (NH), in order to estimate the energy ba[...]texto impreso
Beltrami, Hugo ; González Rouco, J. Fidel ; Stevens, M. Bruce | American Geophysical Union | 2006-05-06General Circulation Models (GCMs) used to distinguish anthropogenic forcing of the Earth's past climate from its natural variability need to be validated by observations. The GCM ECHO-g was used to produce three millennial simulations of the Ear[...]texto impreso
Lucio Eceiza, Etor Emanuel ; González Rouco, J. Fidel ; García Bustamante, Elena ; Navarro, Jorge ; Rojas Labanda, Cristina ; Beltrami, Hugo | Amer Meteorological Soc. | 2020-03The variability of the surface zonal and meridional wind components over northeastern North America during June–October is analyzed through a statistical downscaling (SD) approach that relates the main wind and large-scale circulation modes. An [...]
