GOES-16 Visible Imagery on 1 June revealed an interesting feature behind a lake-enhanced cold front that swept south into Indiana and Illinois (another aspect of this feature is discussed here). Atmospheric waves developed in the cloud layer over the south shore of Lake Michigan and propagated upwind towards Chicago. The... Read More
GOES-16 (GOES-East) Low-level (7.3 µm), Mid-level (6.9 µm) and Upper-level (6.2 µm) Water Vapor images (above) revealed an interesting packet of gravity waves in the vicinity of Guadalupe Island (west of Baja California) on 15 March 2018. The mechanism forcing these waves was not entirely clear, making it a suitable candidate for the “What... Read More
GOES-16 data posted on this page are preliminary, non-operational and are undergoing testingHigh Dewpoints in mid-Summer in the Upper Midwest often leads to stratus and fog over Lake Superior. Such was the case on 10 July 2017, with dewpoints in the 50s and 60s F (GOES-16 Visible images with surface observations) and mid-lake water temperatures... Read More
An interesting linear feature appeared over the East Pacific Ocean on GOES-15 (GOES-West) Water Vapor (6.5 µm) images (above) on 23 May 2017, which at first glance immediately nominated it for the “What the heck is this?” blog category. A contrail was ruled out, since it was not oriented along... Read More
