Stable isotope variability (δ18O, ‰) between 2013 and 2017 from the stable isotope monitoring network in Costa Rica. a Caribbean and Pacific slopes are denoted by red and cyan colors, respectively. Black arrows represent three main climatic features: east-west trade winds, displacement of the ITCZ (Intertropical Convergence Zone), and the MSD (Mid-summer drought). b Power spectrum of δ18O (spectrum amplitude, ‰) with Red Noise spectrum and 90% confidence interval (red and green lines, respectively) generated using REDFIT. The numbers denote the most significant frequency patterns
