Typhoon Vongfong IMERG Rainfall Totals
The first typhoon of the season, Vongfong, struck the central Philippines this past week (where it is known as Ambo) as a strong category 2 storm, bringing strong winds and locally heavy rainfall. Vongfong formed into a tropical depression in the southern Philippine Sea west of Palau on Sunday May 10th from a disturbance that had been slowly making its way westward over the past several days. After becoming a depression, the system moved northward toward the central Philippine Sea and slowly began to intensify. Then, on the 12th when it reached tropical storm intensity, Vongfong’s northward...

GPM Observes Hot Tower in Florida Squall Line

At 9:26pm on Sunday April 19, 2020, NASA's GPM satellite observed an extremely vigorous convective storm cell embedded within a squall line that had produced tornadoes earlier that evening along the US Gulf Coast. NASA's GPM satellite flew over the portion of this squall line that extended over the Atlantic Ocean, 350 miles (500 kilometers) east of Florida's Coast. The Dual-Frequency Precipitation Radar (DPR) observed a storm cell whose updrafts were strong enough to lift small ice particles into the stratosphere 15.8 km above the ocean surface. Equally remarkable is that the updrafts were

GPM Measures Heavy Rainfall from "The Dragon" Cyclonic Storm System in the Middle East

GPM observed the early stages of a strong cyclonic system that developed over northern Africa just off the southern Mediterranean coast on March 11, 2020. The GMI measured heavy rain rates over some parts of Egypt, including the region around Cairo. View fullscreen By March 12, 2020, the cyclonic system that developed over northern Africa had intensified and was nicknamed 'The Dragon' on social media and news outlets, as it caused severe flooding in northern Egypt. Both the GMI and the DPR measured heavy rain rates across two of the storm's bands in this GPM overflight. View fullscreen On
