Record Warm Tropical South Atlantic Index/El Nino Inspired Hot/Dry Summer Most of Brazil

The tropical South Atlantic continues to observe record warm ocean temperatures. The influence on summer climate of the anomalous warmth was significant. Strong difluence in the upper atmosphere across the warm water zone represents anomalous convection (thunderstorm activity). To compensate for the rising air motion, an area of subsidence (sinking motion) over South America was observed during meteorological summer. The sensible weather result was drier and hotter than normal climate across much of Brazil. Of course, El Nino also enhanced this climate anomaly.

Upper Ocean Heat to Support El Nino Almost Gone

The upper ocean heat required to support El Nino is almost gone east of the Deadline. Subsurface warmth remains near the Dateline but is sharply cooler in the east-central and far east subsurface region. Anomalous warmth required in the subsurface to sustain El Nino is fading fast.
