GPM Sees More Powerful Tropical cyclone 06P (ULA)

The GPM core observatory satellite had an excellent daytime view of tropical cyclone 06P (ULA) on December 30, 2015 at 2358 UTC. The tropical cyclone had moved to the east-southeast of Samoa in the South Pacific Ocean with maximum sustained winds increasing to about 50 kts (58 mph). The rainfall pattern derived from GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed that 06P was much better organized. Powerful thunderstorms at the center of the tropical cyclone were found by DPR to be dropping rain at a rate of over 66 mm (2.6 inches) per hour. GPM's

GPM Sees Tropical Cyclone Forming

The GPM core observatory satellite passed above tropical cyclone 06P when it was forming in the south Pacific Ocean north of Samoa on December 29, 2015 at 1321 UTC. A rainfall analysis was performed using data collected at that time by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments. Data from GMI were used to calculate that rain was falling at a rate of over 83.6 mm (3.29 inches) per in a feeder band northeast of the low's center. Radar data from GPM's DPR Ku band radar were used to show the 3-D structure of precipitation within the forming tropical
