The strengthening “warm blob” of SSTA to the east of Argentina is well-correlated to anomalous high-pressure ridging aloft. At times, that high-pressure influence causes dryness and anomalous heat in Argentina likely to expand northward into Southern Brazil during the summer season. To compensate for the upper ridge, a wet low-pressure trough (correlated to slightly cool SSTA east of Brazil) is also likely to persist and cause a wet pattern for north and east portions of Brazil into the summer 2022-23 season.

According to NOAA/SFSC the 2022 Northeast Pacific "warm blob" (NEP22A) has reached a sufficient intensity and aerial coverage making NEP22A the 4th most intense in the 40-year record. This feature, semi-permanent since 2014, has been well-correlated to a persistent upper-level pattern in the northern hemisphere featuring a drought-enhancing western North America drought and presence of a "polar vortex" sometimes capable of delivering extreme cold to the U.S. during winter.
