A mechanism for the multidecadal modulation of ENSO teleconnection with Europe.
(Springer, 2014-10-26)El Niño phenomenon is the main oceanic driver of the interannual atmospheric variability and a determi- nant source of predictability in the tropics and extratrop- ics. Several studies have found a consistent and statisti- ... -
A Review of ENSO Influence on the North Atlantic. A Non-Stationary Signal
(MDPI journals, 2016-06-25)The atmospheric seasonal cycle of the North Atlantic region is dominated by meridional movements of the circulation systems: from the tropics, where the West African Monsoon and extreme tropical weather events take place, ... -

ENSO influence on the North Atlantic European climate: A non-linear and non-stationary approach
(Springer, 2015-12-29)ENSO impact on the North Atlantic European sector (NAE) is still under discussion. Recent studies have found a non stationary feature of this teleconnection, suggesting an effective modu- lating role of the ocean mean ... -
ENSO Influence on Western European Summer and Fall Temperatures.
(American Meteorological Society, 2021)In certain regions, such as Europe, the increase in global air temperatures in the world is translated into more frequent extreme events. Recent studies suggest that the increasing intensity in heatwaves seems to be related ... -

The separation of global horizontal irradiance (GHI) into its direct and diffuse components is necessary in a variety of applications, most specially in solar energy utilization, where knowledge of direct normal irradiance ... -
Impact of increased resolution on the representation of the Canary upwelling system in climate models
(European Geosciences Union, 2022-11-17)We investigate the representation of the Canary upwelling system (CUS) in six global coupled climate models operated at high and standard resolution as part of the High Resolution Model Intercomparison Project (HighResMIP). ... -
Influence of ion size effects on the electrokinetics of aqueous salt-free colloids in alternating electric fields
Carrique-Fernández, Félix; Ruiz-Reina, Emilio; Arroyo Roldán, Francisco José; Delgado Mora, Ángel Vicente (American Physical Society (APS), 2020)
Electrokinetics is an important tool for the characterization of colloids because of its sensitivity to the electrical properties of particle-solution interfaces. Its rigorous description may require inclusion of the effects ... -
