The Himawari-9 Target sector monitored the evolution of Typhoon Mawar from its inception. The animation above (it re-centers occasionally) shows the initial intensification of the system, a brief but notable weakening just prior to moving close to Guam, and then reintensification to the west-northwest of the Marianas. The animation... Read More
Target Sector (2.5-minute interval) JMA Himawari-9 Visible and Infrared images (above) covered the period +/- 2 hours when Super Typhoon Mawar reached Category 5 intensity at 0600 UTC on 25 May 2023. Mesovortices within the eye were evident in Visible imagery, with the eye exhibiting a “stadium effect” geometry (two signatures that are often associated with... Read More
Typhoon Mawar wobbled north during the day on 24 May and moved through the Rota channel between the islands of Guam to the south and Rota to the north, as shown in the animation of Himawari-9 Target Sector Band 3 (Visible, 0.64 µm) imagery above. The track path from the... Read More
Himawari-9 Infrared Imagery, above, shows Mawar as it develops and eye and strenghtens to Super Typhoon status. The animation above shows a well-developed symmetric storm with good outflow from all quadrants. The eye is seemingly in steady state from about 0300-0900 UTC, after which time its size shrinks. The 0600... Read More
