This loop of daily GOES-8 ASADA experimental smoke product images shows the southward movement of the large smoke pall from 30 August to 02 September 1998. Wind streamlines at 700 millibars (about 3.0 km in altitude) indicate that an anticyclone was in place over southeastern Brazil during this period. Northerly flow along the western periphery of this anticyclone helped to advect the smoke southward from Brazil into Bolivia, Paraguay, and eventually northern Argentina. Convection over northeastern Argentina on 02 September produced rain that appeared blue in color, due to the large amount of ash and smoke particulate that was scavenged by the precipitation.
