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
Calvo Fernández, Natalia ; García, Rolando R. ; García Herrera, Ricardo ; Gallego Puyol, David ; Gimeno Presa, Luis ; Hernández Martín, Emiliano ; Ribera Rodríguez, Pedro | American Meteorological Society | 2004-10The El Niño-Southern Oscillation (ENSO) signal in the troposphere and lower stratosphere was investigated using Microwave Sounding Unit (MSU) data for the period 1979-2000. Empirical orthogonal functions (EOFs) were computed separately for zonal[...]texto impreso
Assessing and understanding the impact of stratospheric dynamics and variability on the earth system
Gerber, Edwin P. ; Butler, Amy ; Calvo Fernández, Natalia ; Charlton-Perez, Andrew ; Giorgetta, Marco ; Manzini, Elisa ; Perlwitz, Judith ; Polvani, Lorenzo M. ; Sassi, Fabrizio ; Scaife, Adam A. ; Shaw, Tiffany A. ; Son, Seok-Woo ; Watanabe, Shingo | American Meteorological Society | 2012-06New modeling efforts will provide unprecedented opportunities to harness our knowledge of the stratosphere to improve weather and climate prediction.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
Marsh, Daniel R. ; Mills, Michael J. ; Kinnison, Douglas E. ; Lamarque, Jean-François ; Calvo Fernández, Natalia ; Polvani, Lorenzo M. | American Meteorological Society | 2013-10The NCAR Community Earth System Model (CESM) now includes an atmospheric component that extends in altitude to the lower thermosphere. This atmospheric model, known as the Whole Atmosphere Community Climate Model (WACCM), includes fully interact[...]texto impreso
Palmeiro Nuñez, Froila María ; Barriopedro Cepero, David ; García Herrera, Ricardo ; Calvo Fernández, Natalia | American Meteorological Society | 2015-09Sudden stratospheric warmings (SSWs) are characterized by a pronounced increase of the stratospheric polar temperature during the winter season. Different definitions have been used in the literature to diagnose the occurrence of SSWs, yielding [...]texto impreso
Calvo Fernández, Natalia ; Prieto, M. R. ; Gallego, D. ; García Herrera, Ricardo | Springer | 2005-11Records of wind strength taken onboard Spanish and French ships during the 1750-1850 period have been digitized and examined using content analysis techniques to derive the equivalent wind strength in terms of the current Beaufort scale, this co[...]texto impreso
García Herrera, Ricardo ; Wilkinson, C. ; Koek, F. B. ; Prieto, M. R. ; Calvo Fernández, Natalia ; Hernández, E. | Springer | 2005-11Meteorological observations made on board ships prior to 1854 have until now been overlooked in climatological research largely as a result of the lack of rigorous abstraction and treatment criteria. However, the CLIWOC project has shown that mi[...]texto impreso
Calvo Fernández, Natalia ; García, R. R. ; Randel, W. J. ; Marsh, D. R. | American Meteorological Society | 2010-07The Brewer-Dobson circulation strengthens in the lowermost tropical stratosphere during warm El Nino-Southern Oscillation (ENSO) events. Dynamical analyses using the most recent version of the Whole Atmosphere Community Climate Model show that t[...]texto impreso
The climatology and future changes of the Brewer–Dobson circulation (BDC) in three climate change scenarios are studied using the latest version of the Whole Atmosphere Community Climate Model (WACCM4), which is fully coupled to an ocean model. [...]texto impreso
Peña Ortiz, C. ; García Herrera, Ricardo ; Ribera, P. ; Calvo Fernández, Natalia | http://dx.doi.org/10.1196/annals.1446.007 | 2008The quasibiennial oscillation (QBO) dominates the variability of the equatorial stratosphere and also affects the circulation and temperature of the extratropical region. In this paper we review previous work showing that the mid- to high-latitu[...]texto impreso
Richter, Jadwiga H. ; Matthes, Katja ; Calvo Fernández, Natalia ; Gray, Lesley J. | American Geophysical Union | 2011-10-21Stratospheric sudden warmings (SSWs) are a major source of variability during Northern Hemisphere winter. The frequency of occurrence of SSWs is influenced by El Nino-Southern Oscillation (ENSO), the quasi-biennial oscillation (QBO), the 11 year[...]texto impreso
Ábalos Álvarez, Marta ; Polvani, Lorenzo ; Calvo Fernández, Natalia ; Kinnison, Douglas ; Ploeger, Felix ; Randel, William ; Solomon, Susan | American Geophysical Union | 2019-03-16It has recently been recognized that, in addition to greenhouse gases, anthropogenic emissions of ozone-depleting substances (ODS) can induce long-term trends in the Brewer-Dobson circulation (BDC). Several studies have shown that a substantial [...]texto impreso
Gallego, David ; García Herrera, Ricardo ; Calvo Fernández, Natalia ; Ribera, Pedro | American Geophysical Union | 2007-06-23A new documentary source of data for wind, atmospheric pressure and air temperature for the city of Cadiz (southern Spain) has been abstracted, analyzed and compared with present-day data. Wind records cover the period 1806-1852 with three obser[...]texto impreso
Calvo Fernández, Natalia ; Giorgetta, Marco A. ; García Herrera, Ricardo ; Manzini, Elisa | American Geophysical Union | 2009-07-14The influence of the quasi-biennial oscillation (QBO) on the Northern Hemisphere (NH) polar vortex response to warm El Nino-Southern Oscillation (ENSO) events and the impact of the warm ENSO events on the QBO signal in the NH polar stratosphere [...]
