An anomalously-deep Hurricane Force low (surface analyses) moved eastward across the southern Bering Sea and eastern Aleutian Islands on 28 October 2022. GOES-18 (GOES-West) Air Mass RGB images (above) included plots of hourly surface reports — which showed some of the strong winds produced by this storm. Peak wind gusts included 75 knots / 86 mph...

A sequence of GOES-16 (GOES-East) Nighttime Microphysics RGB and Day Snow-Fog RGB images (above) showed the nocturnal development of lake effect fog/stratus plumes (lighter shades of yellow), which drifted northward from Lake Sakakawea in northwestern North Dakota on 26 October 2022. Two of the fog/stratus features moved across the Tioga and Stanley areas, where surface... Read More
Himawari-9 is slated to become operational (replacing Himawari-8, which has been operational at 140.7o E Longitude since 2015!) on 13 December 2022 (Link). One change that users might observe arises from the slightly shorter central wavelength in the shortwave infrared band (Band 7). On Himawari-8, the central wavelength is 3.885... Read More
1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) and Day Cloud Phase Distinction RGB images (above) showed the compact exposed low-level circulation of Tropical Invest 94L as it moved northward away from Bermuda (station identifier TXKF) on 25 October 2022. In spite of Invest 94L moving through an environment of increasing deep-layer wind shear,... Read More
