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

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

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)

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 Flies Over Tropical Cyclone Florence
Download in High Resolution from the NASA Goddard Scientific Visualization Studio GPM passed over Tropical Storm Florence on September 7, 2018. As the camera moves in on the storm, DPR's volumetric view of the storm is revealed. A slicing plane moves across the volume to display precipitation rates throughout the storm. Shades of green to red represent liquid precipitation. Frozen precipitation is shown in cyan and purple. NASA's Global Precipitation Measurement mission or GPM core observatory satellite flew over Tropical Storm Florence on September 7, 2018. At that time, the storm was...

GPM Sees Tropical Cyclone Jebi Threaten Japan

Japan has been afflicted by several tropical cyclones and other extreme weather this summer. The Joint Typhoon Warning Center (JTWC) predicts that yet another typhoon called JEBI will be approaching the main islands of Japan early next week. Warm ocean temperatures and low vertical wind shear are providing a favorable environment for JEBI's intensification. The JTWC predicts that the typhoon will have peak sustained winds of 115 kts (132 mph) as it moves over the northern Pacific Ocean toward Japan next week. The GPM core observatory satellite passed above on August 28, 2018 at 1816 UTC when

Tropical Cyclone Mekunu Examined With GPM Satellite

The second tropical cyclone in less than a week has formed in the western Arabian Sea early on May 22, 2018. This tropical cyclone called MEKUNU is intensifying as it heads toward Oman. The Joint Typhoon Warning Center (JTWC) predicts that MEKUNU will have winds of about 85 kts (98 mph) when it hits southwestern Oman in about three days. This will make it the equivalent of a category two hurricane on the Saffir-Simpson hurricane wind scale. Tropical cyclone MEKUNU follows on the heels of destructive and deadly tropical cyclone SAGAR that just made landfall over northwestern Somalia a few days

Potential Eastern Pacific Tropical Cyclone Viewed By GPM

The Eastern Pacific hurricane season officially starts on May 15, 2018. A low pressure center located well to the southwest of the Baja California Peninsula may develop into this area's first tropical cyclone of 2018. Low vertical wind shear and warm ocean temperatures in the vicinity of the low are providing favorable conditions for this low's development into a tropical cyclone. If it develops it will be called Aletta. The GPM core observatory satellite passed over the center of the most intense convective storms in this potential tropical cyclone. Rainfall data collected by GPM's satellite

GPM Satellite Views Tropical Cyclone Flamboyan's Rainfall

Tropical cyclone FLAMBOYAN formed in the middle of the South Indian Ocean well to the west of Australia on April 28, 2018. Today FLAMBOYAN's wind speeds have increased to about 70 kts (81 mph) as the tropical cyclone curved toward the south-southwest around the subtropical ridge. The Joint Typhoon Warning center (JTWC) predicts that FLAMBOYAN will start weakening soon as it moves even farther to the south and encounters increasing vertical wind shear and colder ocean temperatures. The GPM core observatory satellite had a good view of the rainfall in tropical cyclone FLAMBOYAN when it flew over

GPM Sees Tropical Cyclone Fakir Forming Near Madagascar

The southwest Indian Ocean cyclone season started on November 15, 2017 and will officially end on April 30, 2018. A tropical cyclone labeled FAKIR by Meteo France formed today near northeastern Madagascar. FAKIR is expected to intensify as it moves toward the southeast and could be a significant tropical cyclone tomorrow. This cyclone season has already seen Madagascar battered and drenched by tropical cyclones Ava, Dumazile, and Eliakim. The GPM core observatory satellite flew above the forming late season tropical cyclone near northeastern Madagascar on April 22, 2018. The satellite's
