GOES-16 True-Color imagery from the CSPP Geosphere site (link showing the data above) on 26 November, above, show features associated with strong flow through Chivela Pass in southern Mexico, gap winds often called Tehuano winds or Tehuantepecers. Strong descent associated with these events can often limit the presence of clouds that... Read More

GOES-17 Infrared imagery, above, centered on American Samoa, shows several low-level cloud lines from which showers are developing (and then rapidly dying, suggestive of strong shear, as noted in this 0600 UTC shear analysis taken from this website). There are also convective elements developing over/near some of the islands. What is the moisture/stability distribution around... Read More

1-minute Mesoscale Domain Sector GOES-17 (GOES-West) Near-Infrared “Snow/Ice” (1.61 µm). Near-Infrared “Cloud Particle Size” (2.24 µm), Shortwave Infrared (3.9 µm), Low-level (7.3 µm). Mid-level (6.9 µm) and Upper-level (6.2 µm) Water Vapor images (above) showed signatures of the DART Mission from Vandenberg Space Force Base in southern California on 24 November 2021. Shortly after the 0620 UTC launch, a warm thermal... Read More

GOES-17 (GOES-West) “Red” Visible (0.64 µm) images (above) showed the motion of pack ice away from the southwest coast of Alaska on 20 November 2021. Strong offshore winds (gusting in excess of 30 knots at times) were causing the ice motion away from the coast into the Bering Sea —... Read More
