GOES-16 “Red” Visible (0.64 µm) images [click to play animation]

Both GOES-16 (GOES-East) and GOES-17 (GOES-West) were placed into the Mode 6 scan strategy for a 3-day period of testing beginning at 1500 UTC on 19  February 2019 — which provides Full Disk images every 10 minutes (instead of every 15 minutes for the more common Mode 3 scan strategy). Further details on GOES-R series scan modes are available here and here. GOES-16 Full Disk “Red” Visible (0.64 µm) images are shown above, with Mid-level Water Vapor (6.9 µm) images below.

One of the more striking features over the North Atlantic Ocean was a rapidly-intensifying Hurricane Force low — an animation that cycles through GOES-16 Visible and Water Vapor images of this system is displayed below.

Full Disk animations of GOES-17 Visible and Water Vapor images are shown below.

The more frequent 10-minute images allowed a short-lived signature of orographic waves within a transient dry slot immediately downwind (northeast) of Atka (PAAK) in the Aleutian Islands of Alaska  (below) — such a signature often indicates a high potential of turbulence. There were also areas of transverse banding seen with the jet stream cirrus just southeast of Atka (another satellite signature of turbulence).
