In the airmass RGB animation, the wide region with several brown/green areas is a dry air mass that indicates a massive anticyclone system over the southern Atlantic ocean. This quasi-stationary high pressure zone is commonly known as the St Helena high. Its centre may move further south during the spring season. The light green areas are low-level clouds that suggest a stable airmass over the ocean. In the animation, these low-level clouds move very slowly in an anticyclonic direction. The upper-level clouds appear to move faster and in the opposite direction to the lower surface flow.

The enhanced IR animation shows the low-level clouds fairly well as grey or dark grey clouds moving anticyclonically (counterclockwise) over southern Atlantic Ocean. The upper-level clouds move faster and in the opposite direction to the lower surface flow. The imagery shows that the high convective cloud tops are absent over the ocean.
