Category 5 Hurricane: Satellite Images Of Super-Typhoon Usagi Passing Philippines And Southern Taiwan b4in.org/bJV The most powerful typhoon of 2013 was passing between northern Philippines and southern Taiwan on Sept. 19. When NASA’s Aqua satellite passed over Usagi, infrared data showed a large area of powerful thunderstorms and heavy rain surrounding the center while NASA’s TRMM satellite measured that heavy rainfall from space. Super-Typhoon Usagi is a monster storm that according the Joint Typhoon Warning Center is headed for a landfall near Hong Kong on Sept. 22 around 1200 UTC/8 a.m. EDT/8 p.m. local time Hong Kong. In this TRMM satellite flyover animation from Sept. 19 rain was falling at a rate of over 140mm/~5.5 inches (red) per hour in the powerful storms within Super Typhoon Usagi’s eye wall. Usagi formed in the open waters of the Philippine Sea about 1,000 km/~620 miles east of the Philippines on September 16, 2013. Usagi rapidly intensified and became a typhoon on Sept. 18 and a Super Typhoon on Sept. 19 when it had estimated maximum winds of close to 140 knots/~161 mph. NASA’s Tropical Rainfall Measuring Mission or TRMM satellite had an excellent view of Usagi September 19, 2013 at 1035 UTC/6:35 a.m. EDT/6:35 p.m. local time Hong Kong. At NASA’s Goddard Space Flight Center in Greenbelt, Md. a precipitation analysis from TRMM’s Microwave Imager (TMI) and Precipitation Radar (PR) instruments was overlaid on an enhanced infrared image from TRMM’s Visible and InfraRed Scanner (VIRS). The most striking feature on the image was Usagi’s small, clear eye. Rain was measured by TRMM’s PR instrument falling at a rate of over 140mm/~5.5 inches per hour in the powerful storms within super typhoon Usagi’s eye wall. More with satellite images b4in.org/bJV
