“…Recently, RQA has proved to be useful in diverse areas, such as economy, physiology, earth sciences, astrophysics, and engineering [10,22]. In particular, RQA has been used to investigate complex synchronization scenarios between coupled chaotic oscillators [24], emergence of GS in networks of structurally different timedelay systems [25,26], and precursors and synchronization of components of the tectonic system [27], among others. The oscillatory nature of diverse hydroclimate phenomena is wellknown, such as those associated with the annual cycle of insolation (12 months), and the quasi-periodic El Niño-Southern Oscillation (3-4 years), which constitutes the most important modulator of interannual climate variability worldwide [28].…”
