GPM Flies Over Hurricane Dorian

GPM Observes Hurricane Dorian Over Bahamas
Wednesday, September 4, 2019
Download in high resolution from the NASA Goddard Scientific Visualization Studio. The NASA / JAXA Global Precipitation Measurement (GPM) Core Observatory flew over Hurricane Dorian on September 1st (5:22pm ET / 21:22 UTC) as the storm was directly over Abaco Island in The Bahamas. The satellite captured data on rainfall rates within the storm as it flew over using its Dual-frequency Precipitation Radar (DPR) and GPM Microwave Imager (GMI). In this animation the multi-satellite GPM IMERG product is shown first to illustrate rainfall rates prior to the overpass. When the camera zooms in data...

IMERG Measures Rainfall in Hurricane Dorian

IMERG Measures Rainfall in Hurricane Dorian
Friday, August 30, 2019
UPDATE 9/9/19: On Monday morning, September 9, Hurricane Dorian was a post-tropical storm after a mid-latitude weather front and cold seas had altered its tropical characteristics over the weekend. On Saturday and Sunday, Hurricane Dorian struck eastern Canada, causing wind damage and bringing heavy rainfall. According to the Associated Press, a peak of 400,000 people were without power in Nova Scotia, Canada, because of Dorian. This graphic shows precipitation that fell during the almost two-week period from August 27 to the early hours of September 9. The near-realtime rain estimates come...

GPM IMERG Measures Rainfall Accumulation from Hurricane Dorian in the Caribbean

GPM IMERG Measures Rainfall Accumulation from Hurricane Dorian in the Caribbean
Hurricane Dorian is packing heavy rain as it moves toward the Bahamas as predicted by NOAA’s NHC or National Hurricane Center. NASA's GPM mission recently analyzed the storm and found heavy rainfall in the storm as it passed through the Caribbean. This image shows estimated rainfall accumulations for the region affected by Hurricane Dorian over the 24 hour period of Aug.27 11:59 UTC to Aug. 28 11:59 UTC. The imagery was generated using the Integrated Multi-satEllite Retrievals for GPM (IMERG) “early run” product. The data indicates that up to 120 mm (4.72 inches) of rainfall accumulated in

IMERG Measures Flooding Rainfall in India

IMERG Measures Flooding Rainfall in India
In early August 2019 a depression formed in the Bay of Bengal that moved over India contributing to heavy rainfall on India's west coast. NASA's satellite data analysis suggests that from August 5 though 11, two feet of rain fell in some places. This estimate is from the GPM-based realtime multi-satellite algorithm called IMERG, which is run at NASA Goddard. Credit: Owen Kelley (NASA GSFC)

Hurricane Barry Makes Landfall in Louisiana

Hurricane Barry Makes Landfall in Louisiana
UPDATE 7/17/19: This GPM IMERG animation shows rainfall accumulations from #HurricaneBarry in the Gulf of Mexico from July 11-16, 2019. Learn more: https://t.co/1QjFLDbD0k pic.twitter.com/CC7J0AsSTW — NASA Precipitation (@NASARain) July 17, 2019 This 6-day animation shows the heavy precipitation that Hurricane Barry (2019) producing from July 11 to 16 in the Gulf of Mexico and the South Central U.S. While forecasters were initially concerned that the largest accumulations would extend far over land, this animation shows that the largest accumulations remained mostly off shore. The

GPM Sees Developing Tropical Storm Barry in the Gulf of Mexico

GPM Sees Developing Tropical Storm Barry in the Gulf of Mexico
NASA / JAXA’s GPM Core Observatory passed over developing Tropical Depression 2 (which was upgraded to Tropical Storm Barry later in the morning) in the Gulf of Mexico the morning of July 11th 2019 at 8:26am CT, capturing estimates of rainfall rates within the storm. The first image shows rainfall rates collected by GPM’s Microwave Imager, while the second image shows 3D rainfall rates within the atmospheric column from GPM’s Dual-frequency Precipitation Radar (DPR). The DPR measured storm top heights as high as 18 km, which is extremely high and indicative of intense thunderstorm activity

GPM Flies Over Flooding Rainfall in Washington DC

GPM Flies Over Flooding Rainfall in Washington DC
Washington DC experienced extreme rainfall the morning of July 8th, 2019 when a cluster of slow-moving thunderstorms moving through the area tapped into a very moist airmass to produce extremely heavy rains, which resulted in flash flooding throughout the region. The storms were triggered by a nearby frontal boundary. The GPM Core Observatory passed over this storm system at 8:51am ET, with its Dual-frequency Precipitation Radar measuring rainfall rates in excess of 100 mm/hr in some areas. Reagan National Airport (DCA) also reported receiving 80 mm of rainfall in one hour, corroborating the

NASA Reveals Heavy Rainfall in Tropical Cyclone Fani

NASA Reveals Heavy Rainfall in Tropical Cyclone Fani
Satellite data revealed heavy rainfall in powerful Tropical Cyclone Fani before it made landfall in northeastern India. Fani brought that soaking rain to the region and continues to drop heavy rainfall on May 3, as it moves toward Bangladesh. NASA’s GPM or Global Precipitation Measurement mission satellite provides information on precipitation from its orbit in space. On May 1 at 7:56 a.m. EDT (1156 UTC), the GPM Core Observatory captured an overpass of the powerful storm as it continued strengthening and moving toward landfall. A 3D image and a color-enhanced rainfall image were created at

GPM Flies Over Developing Tropical Storm Idai Twice

GPM Flies Over Developing Tropical Storm Idai Twice
Intense Tropical Cyclone Idai started as a tropical depression on the 4th of March, 2019, off the coast of Mozambique. After making landfall over Mozambique it turned back over the Mozambique Channel and strengthened to become a tropical cyclone on the 10th of March. The GPM satellite captured the cyclone with both the GPM Microwave Imager (GMI) and the Dual-frequency Precipitation Radar (DPR) on the 11th of March at 04:36 UTC when the storm was in the middle on the Mozambique Channel. The DPR captured a well-developed eye, seen at the center of the image. It flew over the storm once again at

GPM Examines Weakening Tropical Cyclone Kenanga

GPM Examines Weakening Tropical Cyclone Kenanga
Tropical cyclone Kenanga has started to weaken as predicted. The GPM core observatory satellite had an excellent view of Kenanga on December 20, 2018 at 1454 UTC when the tropical cyclone's maximum sustained winds had decreased to about 90 kts (103.5 mph). That GPM pass also showed that the eye that was so prominent a day earlier had filled. Data collected by the satellite's Microwave Imager (GMI) and GPM's Dual-Frequency Precipitation Radar (DPR) instruments revealed through the overcast that powerful storms south of Kenanga's center of circulation were still producing very heavy rainfall
