GPM Examines Tropical Cyclone Gita Over Samoa

Recently formed tropical cyclone GITA was drenching Samo when the GPM core observatory satellite passed above on February 9, 2018 at 1426 UTC. Data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed the area and intensity of precipitation associated with the tropical cyclone. The area covered by GPM's radar swath is shown in lighter shades. GITA was producing heavy rainfall over a large area that included the islands. The center of the intensifying tropical cyclone was located just to the south of the islands. Rainfall in that area was

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

Intensifying Tropical Cyclone Moving Over Samoan Islands

The TRMM satellite passed above an intensifying tropical cyclone in the South Pacific Ocean called Evan on December 11, 2012 at 1759 UTC. Evan is predicted to attain hurricane force winds on December 13, 2012 when it is moving through the Samoan Islands. An analysis of Evan's rainfall from TRMM's Precipitation Radar (PR) and Microwave Imager (TMI) shows that Evan already had an eye-like structure at the time of this TRMM orbit.
