GOES-16 (GOES-East) Mid-level Water Vapor (6.9 µm) images (above) showed the circulations associated with a pair of Hurricane Force low (surface analyses) during the 13-15 February 2020 period. At the limb of the GOES-16 Full Disk view, plots of hourly surface wind revealed gusts in the 70-80 knots range at stations in... Read More

GOES-16 (GOES-East) “Clean” Infrared Window (10.35 µm) images (above) showed a large Mesoscale Convective System (MCS) west of Resistencia (station identifier SARE) in far northern Argentina on 14 February 2020 — this MCS developed southeast of an area of low pressure that was situated well north of a slow-moving cold front...
