GPM Examines Upgraded Hurricane Leslie
The GPM core observatory satellite passed above hurricane Leslie on October 3, 2018 at 7:33 AM EDT (1133 UTC). Leslie had just been upgraded to a hurricane by the National Hurricane Center (NHC). GPM's Microwave Imager (GMI) instrument collected data that revealed light to moderate convective rainfall in Leslie's clearly evident eye wall. Very little precipitation was shown by GPM in the center of the hurricane's nearly circular eye. Algorithms developed by NASA's Precipitation Measurement Missions (PMM) science team indicated that rain was falling at over 1.8 inches (45.7 mm) per hour within

GPM Sees Walaka Becoming A Powerful Hurricane

GPM Sees Walaka Becoming A Powerful Hurricane
The GPM core observatory recently had a couple good looks at tropical storm Walaka as it was intensifying into a powerful hurricane. GPM passed directly over tropical storm Walaka when it was located south of the Hawaiian islands on September 30, 2018 at 8:38 AM HST (1838 UTC). Data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed that Walaka was well organized and very close to hurricane intensity. GPM's Radar (DPR Ku Band) data revealed intense convective storms in a large feeder band that was wrapping around the tropical storm's

We Want You to Go to Class! Our students desperately need to have some face to face time with scientists and engineers who are doing amazing things to make their world a better place. That means you guys! From time to time, you may be invited to give a presentation on your work to kids in some context- and we want to make it easier for you. You might even reach out yourself to your local school and offer to come in and give a talk. Having been a classroom teacher across all grade levels by the time I finished my illustrious career, I know personally the joy of having real STEM professionals...

GPM Views Cat. 2 Typhoon Trami Moving Towards Japan

GPM Views Cat. 2 Typhoon Trami Moving Towards Japan
View fullscreen in STORM Event Viewer Once a Category 5 Super Typhoon, Trami has become rooted in place due to a lack of steering flow. This has caused the storm to deplete the warm waters beneath it and it has since weakened to a Category 2 with maximum winds of 90 knots. It maintains a broad eye and once it begins moving again, is likely to reintensify at least somewhat as it zooms northeastward over the Ryukyu Islands and into the southern coast of Japan. Wind impacts are likely to be exacerbated by its forward speed and current forecasts expect it to have widespread impacts in a region

GPM View Hurricane Rosa in the Eastern Pacific

GPM View Hurricane Rosa in the Eastern Pacific
The GMI overflight here shows a clear center of circulation with much of the intense convection on the south side of Hurricane Rosa, a Category 1 storm with winds of 75 knots. It is expected to continue intensifying over the next couple days before it runs into strong shear and cooler waters off the Baja California coast. Forecasts suggest it will make landfall in Northern Baja as a tropical storm, with its primary impacts being heavy rainfall and flash flooding over the Desert Southwest.
