García Herrera, Ricardo ; Ribera, Pedro ; Gimeno, Luis ; Hernández Martín, Emiliano | Springer | 2000-02The North Atlantic Oscillation (NAO) and the Southern Oscillation (SO) are compared from the standpoint of a possible common temporal scale of oscillation. To do this a cross-spectrum of the temporal series of NAO and SO indices was determined, [...]texto impreso
Nieto, Raquel ; Gimeno, Luis ; Torre, Laura de la ; Ribera, Pedro ; Gallego, David ; García Herrera, Ricardo ; García, José Agustín ; Nuñez, Marcelino ; Redaño, Ángel ; Lorente, Jerónimo | American Meteorological Society | 2005-08-15This study presents the first multidecadal climatology of cutoff low systems in the Northern Hemisphere. The climatology was constructed by using 41 yr (1958-98) of NCEP-NCAR reanalysis data and identifying cutoff lows by means of an objective m[...]texto impreso

García Herrera, Ricardo ; Gimeno, Luis ; Ribera, Pedro ; Hernández, Emiliano ; González, Ester ; Fernández, Guadalupe | Springer | 2007-07This paper analyses five hurricanes that occurred in the period 1600 to 1800. These examples were identified during a systematic search in the General Archive of the Indies (AGI) in Seville. The research combined the expertise of climatologists [...]texto impreso
Gimeno, Luis ; Ribera, Pedro ; Iglesias, Raquel ; Torre, Laura de la ; García Herrera, Ricardo ; Hernández Martín, Emiliano | Inter-Research | 2002-06-14This study characterizes the influence of the El Niño-Southern Oscillation (ENSO) and the North Atlantic Oscillation (NAO) on the most important crops in Spain using statistical analysis of the response of historical yields to ENSO and NAO phase[...]texto impreso
Prieto, Rosario ; Herrera, Roberto ; Doussel, Patricia ; Gimeno, Luis ; Ribera, Pedro ; García Herrera, Ricardo ; Hernández, Emiliano | Australian Govt. Publ. Serv. | 2001-06Using documentary sources, a series of the annual number of snow days in the Mendoza area of Argentina has been constructed. Analysis of the series using Singular Spectrum Analysis (SSA) and the Maximum Entropy Method (MEM) showed that the numbe[...]texto impreso
Gimeno, Luis ; De la Torre, Laura ; Nieto, Raquel ; Gallego, David ; Ribera, Pedro ; García Herrera, Ricardo | Pergamon- Elsevier Science Ltd | 2007-11We studied the main climatological features of the Arctic and Antarctic stratospheric vortices, using a new approach based on defining the vortex edge as the 50 hPa geostrophic streamline of maximum average velocity at each hemisphere. Given the[...]texto impreso
Gallego, David ; Ribera, Pedro ; García Herrera, Ricardo ; Hernández, Emiliano ; Gimeno, Luis | Springer | 2005-05A new jet stream description, defined as the geostrophic streamline of maximum average velocity is proposed. An objective algorithm for detecting and tracking the jet has been developed, tested and applied to the NCEP/NCAR 200-hPa geopotential h[...]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
García Herrera, Ricardo ; Gimeno, Luis ; Ribera, Pedro ; Hernández Martín, Emiliano | American Geophysical Union | 2005-02-04Spanish historical documents from the Archivo General de Indias (General Archive of the Indies) have been used to identify Caribbean hurricanes and storms from the sixteenth to the nineteenth centuries. These sources provide previously unrecorde[...]texto impreso
García Herrera, Ricardo ; Ribera, Pedro ; Hernández Martín, Emiliano ; Gimeno, Luis | American Geophysical Union | 2007-03-22In recent years, the population and the value of properties in areas prone to tropical cyclone (TC) have increased dramatically. This has caused more attention to be placed on the characterization of TC climatologies and the identification of th[...]texto impreso
García Herrera, Ricardo ; Calvo Fernández, Natalia ; Gallego, David ; Hernández Martín, Emiliano ; Gimeno, Luis ; Ribera, Pedro | John WiIley & Sons LTD | 2003-02A strong decreasing trend in the Canary Islands' precipitation is detected by studying daily rainfall time series for the second half of the 20th century. An analysis of the extreme events shows that this trend is due mainly to a decrease in the[...]texto impreso
García Herrera, Ricardo ; Gimeno, Luis ; Hernández Martín, Emiliano ; Prieto, Rosario ; Ribera, Pedro | Inter-Research | 2000-03-20This study presents the preliminary results obtained in the reconstruction of the North Atlantic atmospheric circulation during the 16th, 17th and 18th centuries using documental sources for the Spanish journeys to America kept in the 'Archivo G[...]texto impreso
García Herrera, Ricardo ; Macias, Antonio ; Gallego, David ; Hernández Martín, Emiliano ; Gimeno, Luis ; Ribera, Pedro | American Meteorological Society | 2003-08Records of taxes collected during the seventeenth and eighteenth centuries contribute to understanding of climatic variability of the subtropical North Atlantic region. Historical documentary sources in the Canary Islands have been used to const[...]texto impreso
Gallego, David ; García Herrera, Ricardo ; Peña Ortiz, Cristina ; Ribera, Pedro | Nature Publishing Group | 2017-11-23A new bicentennial series of the Australian monsoon strength based on historical wind observations has allowed for the assessment of the variability of this system since the early 19th century. Our series covers a period in which the scarcity of[...]
