JMA Himawari-8 Upper-level Water Vapor (6.2 µm) images (above) revealed 2 distinct pulses of long-lived gravity waves that propagated northward/northwestward/westward from the coast of Western Australia during the 20-22 October 2019 period. These waves appear to have been generated by thunderstorms near and along the coast — and traveled as... Read More
1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Clean” Infrared Window (10.35 µm) images (above) showed thunderstorms that produced tornadoes, large hail and damaging winds (SPC storm reports) in the Dallas/Fort Worth, Texas area after sunset on 20 October 2019. One of the tornadoes produced EF-3 damage in North Dallas.In a larger-scale view of GOES-16 Infrared images (below), other thunderstorms were... Read More
1-minute Mesoscale Domain Sector GOES-17 (GOES-West) “Red” Visible (0.64 µm) and “Clean” Infrared Window (10.35 µm) images (above) showed thunderstorms that developed along a fast-moving cold front, producing a swath of damaging winds (SPC storm reports) across southern Idaho on 19 October 2019.5-minute GOES-17 Mid-level Water Vapor (6.9 µm) images (below) displayed signatures of a jet stream and shortwave trough...

An animation sequence of GOES-17 (GOES-West) Mid-level Water Vapor (6.9 µm) images with surface reports, then contours of PV1.5 pressure, followed by Air Mass Red-Green-Blue (RGB) images (above) showed the remnants of Typhoon Hagibis in the southern Bering Sea on 14 October 2019. During this time period, the extratropical cyclone was analyzed... Read More
