The South Atlantic anticyclone
remains around 35 to 40oS in the Tristan/Gough longtitude.
The same author states that the most drastic changes would occur in the Amazon as a consequence of anomalies in the Walker circulation and the de-intensification of the South Atlantic Anticyclone
The weak South Atlantic anticyclone
remains limited throughout the period and because there is little ability to ridge round the continent, any development of a cell away to the east is restricted.
Yet, the promising pattern of airflow between a distant anticyclonic core to the east and the south Atlantic anticyclone
shows little sign of departure.
We have had several occasions where the South Atlantic anticyclone
buds off a ridge which squeezes around a vortex, blocking its eastward movement to some degree, while advecting some of its air flow into the vortex pattern.
The succeeding ridge of the South Atlantic anticyclone
was picking up air about 55 to 60oS latitude and circulating this northward.
