An unusually hostile climate pattern has emerged in South America during the 2021-22 warm season. Anomalous heat and dryness have propelled a drought in Paraguay to Southeast Brazil to Northern Argentina while excessive rains have plagued Brazil. While La Nina has contributed to this pattern, the more likely specific catalyst is the semi-permanent upper-level low-pressure trough southeast of Brazil extending northwestward into Brazil to cause convective rains compensated for by subsidence on the back side of that rainfall and centered on Paraguay and Argentina to cause just-the-opposite climate pattern – dryness and heat to accelerate drought.

Subsurface equatorial Pacific Ocean warmth continues to shift eastward across the East Pacific decaying the cool waters that keep La Nina going. The Nino34 SSTA region has warmed to -0.6C as weak La Nina barely hangs on.

The convective phase of the Madden Julian oscillation (MJO) is forecast to strengthen in the same position over the next 2 weeks possibly lingering into March. To compensate for this vast region of convection, the downstream effect is an area of subsidence extending across South America. The influence on climate is profound. The immediate important influences include an expansive very heavy rainfall pattern over Southeast Asia, the eastern Indian Ocean and Indonesia while the influence on South America is to make the climate drier.
