Stratospheric role in interdecadal changes of El Niño impacts over Europe.
(Springer, 2018-04-02)The European precipitation response to El Niño (EN) has been found to present interdecadal changes, with alternated periods of important or negligible EN impact in late winter. These periods are associated with opposite ... -
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 ... -
Multidecadal Modulation of ENSO Teleconnection with Europe in Late Winter: Analysis of CMIP5 Models
(American Meteorological Society, 2016-11-15)Many studies point to a robust ENSO signature on the North Atlantic–European (NAE) sector associated with a downstream effect of Rossby wave trains. Some of these works also address a nonstationary behavior of the ... -
Tropical North Atlantic Response to ENSO: Sensitivity to Model Spatial Resolution
(American Meteorological Society, 2022-01-01)In this study, the ENSO teleconnection with the tropical North Atlantic (TNA) sea surface temperatures (SSTs) in boreal spring is analyzed in ocean–atmosphere coupled global circulation models. To assess the role played ... -
El Niño as a predictor of round sardinella distribution along the northwest African coast
(2020-05-25)The El Niño Southern Oscillation (ENSO) produces global marine environment conditions that can cause changes in abundance and distribution of distant fish populations worldwide. Understanding mechanisms acting locally on ... -
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, ... -
Potential SST drivers for Chlorophyll-a variability in the Alboran Sea: A source for seasonal predictability?
(Frontiers Media, 2022)This study investigates the link between large-scale variability modes of the sea surface temperature (SST) and the surface chlorophyll-a (Chl-a) concentration in spring along the northern flank of the Alboran Sea. To this ... -
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 ... -
Multidecadal modulation of El Niño influence on the Euro-Mediterranean rainfall.
(American Geophysical Union, 2012)[1] El Niño influence on the Euro-Mediterranean Rainfall (EMedR) has changed along the 20th century, and the reasons for this lack of stationarity, which represents an important issue in the climate change context, are ... -
Solar irradiance component separation benchmarking: The critical role of dynamically-constrained sky conditions
Ruiz-Arias, José Antonio; Gueymard, Christian A. (2024-07-01)
The decomposition of global horizontal irradiance into its direct and diffuse components is critical in many applications. To guarantee accurate results in practice, the existing separation techniques need to be validated ... -
