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.

Super Typhoon Trami's Rainfall Examined By GPM

The GPM core observatory satellite probed super typhoon TRAMI when it traveled above the northwestern Pacific Ocean on September 24, 2018 at 1203 UTC. At that time TRAMI had maximum sustained winds estimated at 130 kts (150 mph). This image shows rainfall measurements that were made using data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments. GPM's GMI showed the locations of extremely heavy rainfall in the super typhoon's well defined circular eye. GPM's radar (DPR Ku Band) coverage was limited because it's swath only included storms on the
GPM Applications Banner: Disasters
Too much or too little rainfall can have significant impacts on populations around the world. As population and global temperatures increase, it is crucial to understand what locations will become more vulnerable to extreme rainfall and drought and the subsequent natural hazards (e.g., landslides) and risks (e.g., lose of property) they impose. Satellites allow us to monitor changes in the precipitation, especially over oceans and regions where ground-based data are sparse. With its near-real-time precipitation estimates and near global coverage, GPM serves as an essential tool for assessing
GPM Applications: Health
Precipitation extremes, from heavy rainfall to droughts, pose great risks to a country’s economic development and human health. Standing water and flooding resulting from heavy rainfall has created societal vulnerabilities to vector and waterborne disease outbreaks such as malaria, schistosomiasis, cholera, and chikungunya, among others. Drought and extreme heat conditions have been associated with a wide range of health hazards including degraded air and water quality. These meteorological extremes also impact the growth of cities such as damaging transportation networks and infrastructures

GPM IMERG Adds Up Heavy Rainfall from Typhoon Mangkhut

#NASA's GPM IMERG data product was used to estimate the devastating heavy rainfall that fell on China and the Philippines from #TyphoonMangkhut. This video shows storm-total and 3-hourly precipitation accumulations from 9/11/17 - 9/17/18.
