NASA's IMERG Used To Analyze Tropical Storm Usagi's Rainfall

NASA's IMERG Used To Analyze Tropical Storm Usagi's Rainfall
Usagi strengthened to hurricane intensity as it approached Vietnam from the South China Sea but weakened to tropical storm intensity when coming ashore. Very heavy rainfall and damaging winds accompanied tropical storm Usagi when it hit Vietnam's southern coast. More than 350 mm (14 inches) of rainfall was reported causing widespread flooding around Ho Chi Minh City. NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG) data were used to show estimates of rainfall accumulation produced by Usagi as the tropical cyclone moved across the South China Sea into Southeast Asia. This IMERG

Tropical Cyclone Gaja's Rainfall Measured With IMERG

Tropical Cyclone Gaja's Rainfall Measured With IMERG
Tropical cyclone Gaja recently caused the deaths of at least 33 people in the southern India state of Tamil Nadu. Gaja's high wind and heavy rains caused landslides and building collapses. Gaja's maximum sustained winds had reached about 75kts (86 mph) when it hit southern India on Friday November 16, 2018. This meant that Gaja was the equivalent of a category one on the Saffir-Simpson hurricane wind scale. Today another tropical low is also moving over southern India and is expected to produce more heavy rainfall in the same area. NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG)

Italy's Extreme Rainfall Examined With IMERG

Italy's Extreme Rainfall Examined With IMERG
During the past week a strong low-pressure system moving through southern Europe battered, drenched and flooded Italy. It caused flooding, landslides and other damage to large areas of the country. The deaths of at least 11 people have been attributed to this stormy weather. High winds knocked down many trees and heavy rainfall from these storms contributed to flooding in large areas of Italy. Venice was inundated when heavy rain fell and a surge of water from the Adriatic Sea was pushed into the city by the storm's very high winds. Data from various satellites, that cover most of the globe

GPM Examines Weaker Tropical Storm Yutu in the South China Sea

GPM Examines Weaker Tropical Storm Yutu in the South China Sea
Typhoon YUTU (known as Rosita in the Philippines) is now threatening the Philippine Island of Luzon. On October 24, 2018 YUTU devastated the northern Mariana Islands of Tinian and Saipan as a super typhoon. One death has been attributed to the typhoon in the Marianas with many structures including schools and hospitals being destroyed. Typhoon YUTU weakened as it moved toward the Philippines and had maximum sustained winds of about 90 kts (103.5 mph) when the GPM core observatory satellite passed above the Philippine Sea on October 29, 2018 at 0212 UTC. This rainfall analysis was developed

GPM Catches Typhoon Yutu Making Landfall

GPM Catches Typhoon Yutu Making Landfall
Friday, October 26, 2018
NASA's GPM Core observatory satellite captured an image of Super Typhoon Yutu when it flew over the powerful storm just as the center was striking the central Northern Mariana Islands north of Guam. Early Thursday, Oct. 25 local time, Super Typhoon Yutu crossed over the U.S. commonwealth of the Northern Mariana Islands. It was the equivalent of a Category 5 hurricane. The National Weather Service in Guam said it was the strongest storm to hit any part of the U.S. this year.

Dangerous Hurricane Willa Probed By GPM Satellite

Dangerous Hurricane Willa Probed By GPM Satellite
Hurricane Willa was moving northward toward the western coast of Mexico when the GPM core observatory passed above on October 21, 2018 at 1:51 PM MDT (1951 UTC). The hurricane had maximum sustained winds of about 95 mph (109 kts). Since then Willa has rapidly intensified and today has winds of 155 mph (135 kts) making it a dangerous category four on the Saffir-Simpson hurricane wind scale. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments collected data showing that hurricane Willa and feeder bands were producing heavy rainfall over a large area. The

GPM Views Downgraded Hurricane Michael Soaking the Eastern U.S.

GPM Views Downgraded Hurricane Michael Soaking the Eastern U.S.
View fullscreen in STORM Event Viewer Hundreds of miles way from its landfall in Mexico Beach, Florida, Michael has been downgraded to a tropical storm, but it continues to pack a punch. Waterlogged regions of the Carolinas from Hurricane Florence are seeing trees toppled in the gusty winds, while rain falling in the Appalachian Mountains is leading to flash flooding and water rescues. Widespread power outages and flooding remain likely as the storm moves to the northeast through the rest of the day.

GPM Scans Tropical Storm Nadine

GPM Scans Tropical Storm Nadine
Tropical Depression fifteen was located southwest of the Cabo Verde Islands when it became tropical storm Nadine early on October 9, 2018. The GPM core observatory collected significant information about Nadine when it scanned the tropical storm's center of circulation on October 10, 2018 at 3:01 AM EDT (0701 UTC). Nadine was a small tropical storm but GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) data revealed that extreme rainfall was occurring in areas around the center of the tropical cyclone. GPM's radar (DPR Ku Band) measurements indicated that rain was

GPM's GMI Measures Weakening Kong-Rey's Rainfall

GPM's GMI Measures Weakening Kong-Rey's Rainfall
The GPM core observatory passed above tropical storm Kong-Rey on October 5, 2018 at 0846 UTC. Kong-Rey was a powerful category five typhoon just a few days ago but increased vertical wind shear and cooler sea surface temperatures have caused the tropical cyclone to weaken dramatically. Tropical storm Kong-Rey had maximum sustained winds of about 55 kts (63 mph) when it was scanned by the satellite. GPM's Microwave Imager (GMI) data were used to gauge the intensity of precipitation around Kong-Rey's center of circulation. Energy observed through clouds by GMI's microwave channels was used to

Dive Into a 360-View of Hurricane Maria

Dive Into a 360-View of Hurricane Maria
Thursday, October 4, 2018
Two days before Hurricane Maria devastated Puerto Rico, the NASA/JAXA Global Precipitation Measurement Core Observatory satellite captured a 3D view of the 2017 storm. At the time Maria was a category 1 hurricane. The 3-D view reveals the processes inside the hurricane that would fuel the storm’s intensification to a category 5 storm within 24 hours. For the first time in 360 degrees, this data visualization takes you inside the hurricane. The precipitation satellite has an advanced radar that measures both liquid and frozen water. The brightly colored dots show areas of rainfall, where green...
