Ajuste de un modelo VAR como predictor de los campos de anomalías de precipitación en centroamérica
Revista de Matemática: Teoría y Aplicaciones, 2012 Cluster analysis was used to identify common patterns of 15 precipitation points of the region, using their anomaly time series as grouping variables. Five clusters where identified through this process.

Theoretical study of the ionospheric dynamo region inside the South Atlantic Anomaly
Earth and Planetary Physics, 2023 The South Atlantic Anomaly (SAA) is a region where the geomagnetic field is significantly lower than that of the surrounding area. On the basis of the models of CHAOS-7.8, Mass Spectrometer Incoherent Scatter Model (NRLMSISE-00), and International ...

Is the Atlantic Ocean driving the recent variability in South Asian dust? [PDF]
Atmospheric Chemistry and Physics, 2021 This study investigates the large-scale factors controlling interannual variability in dust aerosols over South Asia during 2001–2018. We use a parameter DA%, which refers to the frequency of days in a year when high dust activity is experienced over a ...

THE SOUTH ATLANTIC ANOMALY (SAA)
, 2023 The South Atlantic Anomaly (SAA) is a geophysical phenomenon characterized by the weakening of the Earth's magnetic field over the South Atlantic Ocean region. AAS has been the subject of study by many scientists around the world, due to its magnitude and potential impact on satellite-based technologies such as navigation and communications.
