GPM Catches a Look at a Rare Tornadic Storm Near the Chesapeake Bay

GPM Catches a Look at a Rare Tornadic Storm Near the Chesapeake Bay
Tornadic storms in Maryland are rare to begin with, let alone in the middle of the night. However, about an hour after midnight in the early morning hours of Monday April 24th at around 1:00 am local time, a severe thunderstorm, which was located at the southern end of a mass of storms and which had just dumped heavy rains over the Washington, DC area, began to cross the Chesapeake Bay near Annapolis, Maryland heading eastward. It is quite common for storms to weaken as they cross the cooler waters of the Bay, but water temperatures are now rather warm, over 80F, which allowed the storm to

A New Multi-dimensional View of a Hurricane

A New Multi-dimensional View of a Hurricane
Wednesday, July 26, 2017
Download in high resolution from the NASA Goddard Scientific Visualization Studio NASA researchers now can use a combination of satellite observations to re-create multi-dimensional pictures of hurricanes and other major storms in order to study complex atmospheric interactions. In this video, they applied those techniques to Hurricane Matthew. When it occurred in the fall of 2016, Matthew was the first Category 5 Atlantic hurricane in almost ten years. Its torrential rains and winds caused significant damage and loss of life as it coursed through the Caribbean and up along the southern U.S...

GMI Monitors Earth's Newest, Giant Iceberg

GPM Sees Larsen-C Ice Shelf Separation
Monday, July 24, 2017
Click here to download the video (.mp4) On July 12, 2017, a giant iceberg broke off Antarctica and a variety of satellites have been used to study it ever since. The Global Precipitation Measurement (GPM) Microwave Imager (GMI) instrument can see the ribbon of relatively warm water and ice that separates the newly formed iceberg from the its parent mass of ice, the Larsen C ice shelf. While the iceberg is separated from the parent iceshelf by only a few kilometers, the GMI instrument is sensitive enough to detect the variation in temperature between this relatively warm gap and the colder ice...

GPM Views Dissipating Hurricane Fernanda

GPM Views Dissipating Hurricane Fernanda
The GPM core observatory satellite had another exceptional view of hurricane Fernanda when it flew over on July 20, 2017 at 0101 UTC. GPM saw a much different hurricane than it viewed a couple days earlier. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) radar instruments found that the dissipating hurricane only contained heavy rainfall in it's northwestern quadrant. Cooler water, dry air, and southwesterly vertical wind shear had caused Fernanda to weaken. GPM's Radar revealed that powerful convective storms in that part of the dissipating hurricane were still

GPM Examines Hurricane Fernanda's Eye

GPM Examines Hurricane Fernanda's Eye
The GPM core observatory satellite had an excellent view of hurricane Fernanda on July 18, 2017 at 0110 UTC. Hurricane Fernanda had weakened from it's peak wind speed of 125 kts (143.75 mph) attained on July 15, 2017 but still had maximum sustained wind speeds of about 95 kts (109 mph). This meant that Fernanda was still a powerful category two hurricane on the Saffir-Simpson hurricane wind scale. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) data showed the location of intense rainfall circling around Fernanda's eye. Measurements by GPM's Radar (DPR Ku band) showed

Forming Tropical Storm Don's Rain Checked By GPM

Forming Tropical Storm Don's Rain Checked By GPM
On Monday July 17, 2017 at 5:00 PM EDT a tropical disturbance in the Atlantic Ocean was upgraded to tropical storm Don, the fourth Atlantic Tropical storm of 2017. The GPM core observatory satellite flew above the forming tropical storm much earlier in the same day at 3:17 AM EDT (0717 UTC). GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments collected data that were used to evaluate precipitation within the forming tropical cyclone. GPM's Radar data swath (shown in lighter shades) covered an area to the west of the greatest amount of rainfall. GPM's radar

Heavy Downpours Cause Flooding In The Midwest

Heavy Downpours Cause Flooding In The Midwest
Heavy rain has resulted in significant flooding in the Midwest during the past week. Water flowing into the Fox River in northeastern Illinois caused serious flooding in that area. Central Indiana and central Ohio have also had remarkable flooding. NASA's Integrated Multi-satelliE Retrievals for GPM (IMERG) data were used to show estimates of rainfall accumulation in the Midwest during the period from July 7-14, 2017. This analysis indicates that parts of Wisconsin, Illinois, Indiana and Ohio had the highest rainfall totals during the period with over 6 inches (152.4 mm) of rain being seen in

Rainfall In Potential Tropical Cyclone Analyzed

Rainfall In Potential Tropical Cyclone Analyzed
A tropical cyclone may be forming in the northwestern Pacific Ocean near Chichi-Jima, Japan. The GPM core observatory satellite flew directly above very strong convective storms in this potential tropical cyclone on July 13, 2017 at 0834 UTC. Rainfall in the area was analyzed using data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments. One area of extremely intense storms was measured by GPM's radar (DPR Ku Band) dropping rain at a rate of over 198mm (7.8 inches) per hour. Data from the GPM satellite's radar (DPR Ku band) was also used to
