From: Oceanic SACZ produces an abnormally wet 2021/2022 rainy season in South America
(a) December, January, and February (DJF) climatology for the period from 2000 to 2021 of Outgoing Longwave Radiation (OLR) shaded (W m−2) and percentage of precipitation (PREC) blue hatched (contours, %) emphasizing areas containing more than 50% of the annual total. (b) Time-series of box-averaged OLR, PREC anomalies over the continent (CNT), the ocean (OCN), and the whole SACZ area (CNT + OCN), and the total number of SACZ events (according to Rosa et al.8) during each DJF season. (c) Cloud top brightness temperature (°C) composite for the seven oceanic SACZ events in DJF 2021/2022. (d) Topography (shaded in m). The CNT and OCN areas are indicated in (a) as polygons in red lines. Symbols in (d) display heavy rainfall (purple circles) and natural disasters (blue squares) resulting from inundations, flash floods, and landslides.
