2.5-minute #Himawari9 Infrared images showed the large eye of Category 4 Cyclone #Narelle as it approached North West Cape in Western Australia: cimss.ssec.wisc.edu/satellite-bl...

2.5-minute #Himawari9 Infrared images suggest that Category 4 Cyclone #Narelle made landfall along Australia's York Peninsula coast just after 2100 UTC.

2.5-minute #Himawari9 Infrared images showed that the eye of Category 4 Cyclone #Narelle was becoming more cloud-filled as the storm began to encounter a more hostile environment of higher wind shear.

2.5-minute #Himawari9 Infrared images showed Cyclone #Narelle rapidly intensifying in the Coral Sea - becoming a Category 2 storm by 1200 UTC and a Category 3 by 1800 UTC. Coldest cloud-top temperatures were -90 to -95 C.

A phenomenon that is especially easy to see there in winter.

2.5-minute rapid scan #Himawari9 Visible images provided a phenomenal view of low-altitude mesovortices within the eye of Category 5 Super Typhoon #Ragasa, as the storm center approached islands within the Luzon Strait (between Taiwan and the Philippines).

2.5-minute rapid scan #Himawari9 Infrared images showed Super Typhoon #Ragasa as it reached Category 5 intensity at 0600 UTC on 21 September. There was a ~1 hour gap in 2.5-minute Target Sector images -- so 10-minute Full Disk images were substituted during the gap.

2.5-minute rapid scan #Himawari9 Visible and Infrared images showed the first few hours after sunrise on Category 4 Typhoon #Ragasa in the Philippine Sea. A partially-clearing eye is occasionally revealing the presence of low-altitude mesovortices.

Ash RGB images from #Himawari9 showed the volcanic cloud from an eruption of #Lewotobi in Indonesia -- this volcanic cloud was a mixture of Ash (shades of red) and SO2 (shades of yellow). Full resolution: cimss.ssec.wisc.edu/satellite-bl...

A lot of fire signatures and smoke plumes were picked up by #Himawari9 🛰️today in northeastern Victoria, #Australia. #bushifires

2.5-minute #Himawari9 Shortwave Infrared images showed that the deadly wind-driven wildfire complex in South Korea (that produced 3 #pyrocumulonimbus clouds) made a rapid eastward run all the way to the coast. More details on the CIMSS Satellite Blog: cimss.ssec.wisc.edu/satellite-bl...

South Korea wildfires seen on 22 Mar and today 26 Mar by #Himawari9 with heat signatures. #SouthKorea #fires #wildfires

2.5-minute #Himawari9 Visible / Shortwave Infrared / Infrared Window images showed signatures of 3 #pyrocumulonimbus cloud pulses (from 0832-0842 UTC) initiated by a wildfire in South Korea -- these are the first documented #pyroCb events on the Korean Peninsula.

South Korea wildfires seen by #Himawari9 earlier today with heat signatures. A state of national disaster has been declared for Ulsan city and North and South Gyeongsang provinces #SouthKorea

Thanks to Japanese Meteorology Agency for parking Himawari-9 above TS Alfred #Himawari9

The image shows a curved earth horizon, viewing towards Antarctica and clouds over the ocean south of Australia. The bottom of the image is dark. Going up we pass the terminator and enter sunlight. The horizon is brighly lit, with the blackness of space above it. Here the image shows a number of thin blueish streaks which are noctilucent clouds. The Himawari 9 satellite is positioned in a geostationary location over the western Pacific Ocean. The satellite is operated by the Japan Meteorological Agency.

The world is becoming a terrifying place, but let’s talk nevertheless for a moment about a wonder of nature: noctilucent clouds (#nlc). They form over high geographical latitudes during midsummer. The image shows nlcs over Antarctica on 27 January 2025 seen by #Himawari9 satellite. 1/7

Severe Tropical Cyclone #Zelia 🌀has made landfall on Ripon Island, Western Australia only about 50 km from Port Headland. Seen by #himawari9 🛰️ #CycloneZelia

2.5-minute #Himawari9 Visible and Infrared images indicate that Category 4 Severe Tropical Cyclone #Zelia is very close to making landfall along the coast of Western Australia, near Port Hedland: cimss.ssec.wisc.edu/satellite-bl...

2.5-minute rapid scan JMA #Himawari9 Infrared images showed #Zelia as it developed a cloud-cleared eye while intensifying from a Category 2 tropical cyclone by 1800 UTC on 12 February to a Category 4 by 0000 UTC on 13 February. Cold overshooting tops were in the -90 to -95C range.

Visible, Shortwave Infrared & Longwave Infrared Window images from #Himawari9 showed a bushfire (shades of black to red in the middle panel) in #Grampians National Park (in Victoria, #Australia) that produced a #pyrocumulonimbus cloud (shades of blue in the bottom panel) on 4th February.

Images from #Himawari9 showed signatures of a wildfire in SE Australia's Grampians Nat'l Park (middle panel) that produced a #pyrocumulonimbus cloud (shades of blue in the bottom panel) - which drifted southeast over Melbourne Airport (YMML).

2.5-minute rapid scan JMA #Himawari9 Visible and Infrared images showed Super Typhoon #ManYi (#PepitoPH) as it made landfall on the Philippines island of Luzon. A notable convective burst developed shortly after the eye became cloud-filled in as it moved inland.

🔴⚠️🌀🇵🇭Unprecedented #landfall of #PepitoPH in #Catanduanes as cat.5(super)#typhoon with gusts at 325km. Now still in cat.5 and gusts at 280kmh towards #Luzon with likely #floods and storm surges in the island.Here the latest 12hrs by #himawari9 #philippines #ClimateEmergency @geraldkutney.bsky.social

Landfall of #Typhoon Kong-Rey 🌀on #Taiwan and in the process the destruction of the inner core by the Central Mountain Range⛰️. Seen in infrared by #Himawari9 🛰️#TyphoonKongRey #KongRey

Eruption of #Marapi 🌋Sumatra, Indonesia this morning was briefly seen by #Himawari9 🛰️before cirrus clouds moved in from the south.

Extensive #Bushfires 🔥 south of the Gulf of Carpentaria, northern Australia🇦🇺 today including the one on Vanderlin Island tweeted earlier. Seen by #Himawari9 🛰️see breeze or glory boundary? hits the smoke in the evening dragging it inland.
