Powerful Hurricane Lane Probed By GPM Satellite
Powerful Hurricane LANE Probed By GPM Satellite
JacobAdmin Mon, 08/20/2018
Hurricane LANE had moved westward into the central Pacific Ocean far southeast of the Hawaiian islands when the GPM core observatory satellite passed above on August 19, 2018 at 1643 UTC. LANE had intensified and had maximum sustained winds reaching about 105 kts (~ 121 mph) at that time. This made it a category three on the Saffir-Simpson hurricane wind scale. The GPM satellite's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments provided highly accurate information about precipitation within the hurricane. GPM's GMI revealed rainfall coverage and GPM's radar (DPR

GPM Passes Over Weakening Hurricane John

GPM Passes Over Weakening Hurricane JOHN
The GPM core observatory satellite provided very good coverage of hurricane JOHN when it passed above the eye of the tropical cyclone on August 8, 2018 at 0:59 AM MDT (0659 UTC). JOHN's maximum sustained wind speeds had started to decrease. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed that most of JOHN's precipitation was then located in the eastern half of the hurricane. A large cloud free area had developed between the center of the hurricane and an intense feeder band wrapping around the northern and western side of the hurricane. GPM's radar

Potential Eastern Pacific Tropical Cyclone Viewed By GPM

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

Weakening Tropical Storm Eugene Investigated With GPM Satellite

Weakening Tropical Storm Eugene Investigated With GPM Satellite
The GPM core observatory satellite had another excellent view of Eastern Pacific tropical storm Eugene on July 11, 2017 at 0231 UTC. Eugene was weakening as it traveled toward the northwest over progressively cooler waters. The only remaining strong convective activity was seen in Eugene's northwestern quadrant. GPM's Dual-Frequency Precipitation Radar (DPR) data revealed that some of these convective storms northwest of Eugene's center of circulation were dropping rain at a rate of more than 70 mm (2.8 inches) per hour. A 3-D view of the dissipating tropical storm was developed using GPM's

Hurricane Eugene formed on July 7, 2017 in the eastern Pacific Ocean south of the Baja Peninsula. Eugene was intensifying when the GPM core observatory satellite flew over on July 9, 2017 at 0236 UTC. Eugene reached it's peak power later that day with it's maximum sustained wind speeds reaching about 100 kts (115.0 mph). The center of GPM's track passed to the west of Eugene's eye. Data collected by GPM's Dual-Frequency Precipitation Radar (DPR) instrument showed that powerful storms in the northwestern quadrant of the hurricane were dropping rain at a rate of over 186 mm (7.3 inches) per hour

Tropical Depression 03W In The Pacific Examined By GPM

Tropical Depression 03W In The Pacific Examined By GPM
Tropical Depression 03W formed in the Pacific Ocean west of Guam on April 24, 2017. The GPM core observatory satellite had an excellent view of TD03W when it flew over on April 14, 2017 at 1901 UTC. The GPM satellite found that the newly formed tropical depression contained some very powerful convective storms. Intense storms in the middle of the organizing convective cluster were dropping precipitation at extreme rates. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments unveiled tall convective storm towers on the eastern side of this cluster of storms that

GPM Observes Tropical Storm Ivette

GPM Observes Tropical Storm Ivette
On August 2, 2016 Ivette became the 11th tropical cyclone this year in the eastern Pacific. Tropical cyclones have formed in the eastern Pacific this year at almost the same frequency as in 2015. Ivette has been moving toward the central Pacific Ocean. Warm ocean water and low vertical wind shear are expected to help Ivette intensify to hurricane intensity in a few days. The GPM core observatory passed over the eastern side of tropical storm Ivette on August 4, 2016 at 0606 UTC. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) data showed that storms around Ivette

Tropical Storm Carlos Viewed By GPM

Tropical Storm Carlos Viewed By GPM
Tropical storm Carlos is the third tropical cyclone in what promises to be a busy 2015 eastern Pacific hurricane season. The GPM core observatory satellite flew directly above Carlos on June 12, 2015 at 0716 UTC. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed that heavy rain was falling in a band of powerful storms to the southeast of the tropical storm's center of circulation. Rainfall was measured by GPM radar (Ku band) falling at a rate of almost 70 mm (2.8 inches) per hour in Carlos' most intense areas of rainfall. Those same radar data were

First 2015 Tropical Storm Forms In Eastern Pacific

First 2015 Tropical Storm Forms In Eastern Pacific
Tropical storm Andres became the first tropical storm of the the 2015 Eastern Pacific hurricane season today at 1500 UTC (9 AM MDT). The GPM core observatory satellite flew over the intensifying tropical cyclone (TD1E) at 1225 UTC ( 6:25 AM MDT). Rainfall data from GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (Ku Band) instruments are shown overlaid on an enhanced GOES-EAST satellite infrared image received at 1230 UTC (6:30 AM MDT). Rain was found by GMI to be falling at a rate of over 60 mm (2.4 inches) per hour in powerful convective storms near Andres' center. Data
