García Herrera, Ricardo ; Barriopedro Cepero, David ; Correoso, Juan Francisco ; Hernández Martín, Emiliano ; Paredes, Daniel | Elsevier Science INC | 2006-02In this paper cloud-to-ground (CG) lightning flashes of 33 Mesoscale Convective Systems (MCSs) over the Western Mediterranean area are analyzed. Mean values of 22% for the positive CG ratio, 1.1 (2.4) for positive (negative) CG multiplicity, 17 [...]texto impreso
Nieto, R. ; Gimeno, Luis ; Añel, J. A. ; Torre, L. de la ; Gallego, D. ; Barriopedro Cepero, David ; Gallego, M. ; Gordillo, A. ; Redaño, A. ; Delgado, G. | Springer Wien | 2007-04The Iberian Peninsula is one of the regions in the world with higher occurrence of cut-off low systems (COL). The aim of this paper is to analyse the weather events (rainfall and cloudiness layer) associated to COLs in the Iberian Peninsula with[...]texto impreso
This paper aims to provide a new blocking definition with applicability to observations and model simulations. An updated review of previous blocking detection indices is provided and some of their implications and caveats discussed. A novel blo[...]texto impreso
Barriopedro Cepero, David ; García Herrera, Ricardo ; González Rouco, J. Fidel ; Trigo, R. M. | Springer | 2010-12A previously defined automatic method is applied to reanalysis and present-day (1950-1989) forced simulations of the ECHO-G model in order to assess its performance in reproducing atmospheric blocking in the Northern Hemisphere. Unlike previous [...]texto impreso
Barriopedro Cepero, David ; Antón Martínez, Manuel ; García García, José Agustín | American Meteorological Society | 2010-07-15This paper analyzes the statistical relationship between the total ozone column (TOC) and atmospheric blocking using 40-yr European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA-40) data for the 1978-98 period, with special [...]texto impreso
Woollings, Tim ; Barriopedro Cepero, David ; Methven, John ; Seok-Woo, Son ; Martius, Olivia ; Harvey, Ben ; Sillmann, Jana ; Lupo, Anthony R. ; Seneviratne, Sonia | Springer Heidelberg | 2018-09Purpose of Review Atmospheric blocking events represent some of the most high-impact weather patterns in the mid-latitudes, yet they have often been a cause for concern in future climate projections. There has been low confidence in predicted fu[...]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
García Herrera, Ricardo ; Díaz, H. F. ; García, R. R. ; Prieto, M. R. ; Barriopedro Cepero, David ; Moyano, R. ; Hernández Martín, Emiliano | American Meteorological Society | 2008-05The authors present a chronology of El Niño (EN) events based on documentary records from northern Peru. The chronology, which covers the period 1550-1900, is constructed mainly from primary sources from the city of Trujillo (Peru), the Archivo [...]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
García Herrera, Ricardo ; Barriopedro Cepero, David ; Lupo, Anthony R. ; Hernández Martín, Emiliano | American Meteorological Society | 2006-03-15In this paper a 55-yr (1948-2002) Northern Hemisphere blocking climatology is presented. Traditional blocking indices and methodologies are revised and a new blocking detection method is designed. This algorithm detects blocked flows and provide[...]texto impreso
Delgado, G. ; Redaño, A. ; Lorente, J. ; Nieto, R. ; Gimeno, L. ; Ribera, P. ; Barriopedro Cepero, David ; García Herrera, Ricardo ; Serrano, A. | Springer Wien | 2007-04This paper reports a cloud cover analysis of cut-off low pressure systems (COL) using a pattern recognition method applied to IR and VIS bispectral histograms. 35 COL occurrences were studied over five years (1994-1998). Five cloud types were id[...]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
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
Wang, Lin ; Chen, Wen ; Zhou, Wen ; Chan, Johnny C. L. ; Barriopedro Cepero, David ; Huang, Ronghui | John WiIley & Sons LTD | 2010-01Blocking variability over the Ural Mountain region in the boreal winter and its relationship with the East Asian winter climate is investigated. The climate shift around mid 1970s has been shown to exert a significant influence on the blocking p[...]
