A rare, mostly clear day over the Great Lakes (and favorable orbital geometry) allowed NOAA-20, above, and Suomi-NPP, below, to image all 5 Great Lakes in one scene. These images were produced from data that were downloaded at the Direct Broadcast site at CIMSS and processed with CSPP and Polar2Grid; ... Read More
GOES-16 (GOES-East) Mid-level Water Vapor (6.9 µm) images with plots of hourly surface weather type (above) showed the broad areal coverage of precipitation across Virginia and North Carolina during the nighttime and morning hours on 28 January 2021. Storm total snowfall and peak wind gusts associated with this event are listed... Read More
As an anomalously-deep 500 hPa low began to move inland over Southern California during the 23 January – 24 January 2021 period, GOES-17 (GOES-West) Air Mass RGB images (above) showed a compact Potential Vorticity (PV) anomaly approaching the coast — and the RAP40 model indicated that the “dynamic tropopause” (defined here as the pressure of the...

GOES-16 (GOES-East) “Red” Visible (0.64 µm) images created using Geo2Grid (above) revealed long trails of lee waves extending northeastward from many of the South Sandwich Islands on 16 January 2021. These lee waves were generated by strong southwesterly winds within the marine boundary layer interacting with the topography of the islands — wind... Read More
