      This perspective paper reviews progress made in the last decades to enhance the communication and use of climate information relevant to the political and economic decision process. It focuses, specifically, on the ...
    • Climatic cues for secondary growth and cone production are sex-dependent in the long-lived dioecious conifer ... 
      Rozas, Vicente; Le Quesne, Carlos; Rojas-Badilla, Moisés; González-Reyes, Álvaro; Donoso, Sergio; Olano, José Miguel (Elsevier B.V., 2019)
      Trees’ growth responses to climate may depend on tree age and site conditions. In dioecious species, sex adds an extra level of complexity due to differential reproductive effort between the sexes and potentially sex-related ...
    • Climatological characterization of puelche winds down the western slope of the extratropical andes mountains ... 
      Montecinos, Aldo; Muñoz, Ricardo C.; Oviedo, Stephanie; Martínez, Andrés; Villagrán, Víctor (American Meteorological Society, 2017)
      The existence of strong easterly winds down the western slope of the south-central Andes in Chile, locallyknown as Puelche winds, has been known by the meteorological community since at least the mid-twentiethcentury. ...
    • A climatology of cutoff lows in the Southern Hemisphere 
      Fuenzalida Ponce, Humberto; Sánchez, Rodrigo; Garreaud Salazar, René (2005)
      The occurrence of cutoff lows (COLs) in the Southern Hemisphere at 500 hPa is studied for a 31-year period using atmospheric NCEP-NCAR reanalysis. The methodology combines objective detection and tracking for cyclonic ...
    • Clinical features and possible founder mutation of the 8bp duplication mutation in the SLC4A11 gene causing ...

    • Clinical neurophysiology standards of EMG instrumentation: twenty years of changes 
      Verdugo Latorre, Renato; Matamala, José Manuel (Elsevier, 2020)
    • Clique coloring B1-EPG graphs 
      Bonomo, Flavia; Mazzoleni, María Pía; Stein, Maya (Elsevier, 2017)
