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
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
Ayarzagüena Porras, Blanca ; Palmeiro Nuñez, Froila María ; Barriopedro Cepero, David ; Calvo Fernández, Natalia ; Langematz, Ulrike ; Shibata, Kiyotaka | Copernicus Publications | 2019-07-26Major sudden stratospheric warmings (SSWs) represent one of the most abrupt phenomena of the boreal wintertime stratospheric variability, and constitute the clearest example of coupling between the stratosphere and the troposphere. A good repres[...]texto impreso
The polar winter stratosphere is dominated by strong thermally-driven westerly winds (Andrews et al. 1987). Every two years on average (Charlton and Polvani 2007), this polar vortex is disrupted by a Sudden Stratospheric Warming (SSW), whereby t[...]texto impreso
Palmeiro Nuñez, Froila María ; Iza San Juan, Maddalen ; Barriopedro Cepero, David ; Calvo Fernández, Natalia ; García Herrera, Ricardo | American Geophysical Union | 2017-03-28This paper examines the outstanding characteristics of the strong 2015-2016 El Nino (EN) winter and its impact over the European region through the stratosphere. Despite being classified as a strong eastern Pacific (EP) EN event, our analysis re[...]
