As West Pacific Tropical Depression 02W — previously discussed in this blog post — intensified to become Tropical Storm Mawar at 1200 UTC on 20 May 2023, 2.5-minute rapid scan JMA Himawari-9 “Clean” Infrared Window (10.4 µm) images (above) showed pulses of cold overshooting tops that frequently exhibited infrared brightness temperatures in the -90 to -95ºC range.

Himawari-9 Infrared Window (11.2 µm) images with an overlay of deep-layer wind shear at 1800 UTC from the CIMSS Tropical Cyclones site (below) indicated that Mawar was moving into an environment of lower shear, which favored a trend of continued intensification.
