Abstract Understanding how climate variability influences corn yield is essential for improving agricultural forecasting and resilience strategies. This study examines the role of four major indices—El Niño Southern Oscillation (ENSO) index related ONI, IOD, AAO TSA—on across Argentina's diverse agro-ecological regions (22° to 39° S latitude). Using historical rainfed data at county level monthly records (1994–2024), we assessed temporal spatial relationships between these indices detrended anomalies. ONI emerged as dominant predictor, particularly in core production region country, where its positive phase correlated strongly with increased rainfall during critical crop growth stages. IOD also exerted a significant influence, although it was more localized seasonally dependent, primarily affecting mid-summer precipitation patterns region. Conversely, effects TSA were weaker even regionally constrained (for Cordoba coastal areas, respectively). A Principal Component Analysis (PCA) including all indexes reinforced findings, highlighting combined overlapping influence rather than simple relationships. Notably, absence clear regional differentiation PCA suggests that signals act broadly Argentina, making difficult generalize predictions based on any single index. These results challenge conventional assumption ENSO alone can reliably forecast outcomes underline necessity multi-index approaches robust modeling. By integrating into predictive frameworks, this research could enhance accuracy, supporting adaptive management strategies face increasing variability.

The Atmospheric Dynamics Mission ADM-Aeolus was successfully launched in August 2018 by the European Space Agency (ESA). Aeolus mission carried a single instrument, first-ever Doppler wind lidar (DWL) space, called LAser INstrument (ALADIN). circled Earth, providing vertical profiles of horizontal line-of-sight (HLOS) winds on global scale. satellite’s measurements filled critical gaps existing observations, particularly remote regions such as Brazilian Amazon. This area, characterized dense rainforests and rich biodiversity, is essential for climate dynamics. weather patterns Amazon are influenced atmospheric circulation driven Hadley cells Intertropical Convergence Zone (ITCZ), which crucial distribution moisture heat from equator to subtropics. data provided can significantly enhance our understanding these complex processes.
