Intensifying Tropical Storm Jelawat Evaluated By GPM

Intensifying Tropical Storm Jelawat Evaluated By GPM
The GPM core observatory satellite flew almost directly above large intensifying tropical storm JELAWAT on March 28, 2018 at 0510 UTC. Rainfall measurements shown here were derived from data collected by GPM's Microwave Imager (GMI) and Dual Frequency Precipitation Radar (DPR) instruments. These satellite instruments provided excellent coverage of JELAWAT's precipitation. GPM's Radar (DPR Ku Band) swath included exceptionally powerful storms within a large intense feeder band that was wrapping around the eastern side of the tropical storm. GPM's DPR revealed that these strong convective storms

Tropical Cyclone Nora's Flooding Rains Measured With IMERG

Tropical Cyclone Nora's Flooding Rains Measured With IMERG
Tropical Cyclone NORA produced heavy rainfall when it came ashore in northwestern Queensland on March 24, 2018 (GMT). NORA's peak intensity of 95 kts (109 mph) was reached when the tropical cyclone was located in the central northern Gulf Of Carpentaria. Winds had decreased slightly to 90 kts (104 mph) by landfall. The Australian Bureau of Meteorology (BOM) reported that NORA produced over 110 mm (4.3 inches) of rain in 24 hours. Flooding, landslides, lost electrical power, and structural damage were also a companion of the tropical cyclone's arrival. After landfall NORA weakened but the

GPM Flies Over Intensifying Tropical Cyclone Nora

GPM Flies Over Intensifying Tropical Cyclone Nora
Intensifying tropical cyclone NORA has been moving southeastward into the Gulf of Carpentaria since it formed in the Arafura Sea north-northeast of Darwin,Australia. The Joint Typhoon Warning Center (JTWC) issued it's first warning for Tropical cyclone NORA on March 22, 2018 at 0900Z. After that NORA's winds increased to over 65 kts (75 mph). That means that today NORA became the equivalent of a category one hurricane on the Saffir-Simpson hurricane wind scale. The GPM core observatory satellite scanned tropical cyclone NORAas it passed above on March 22, 2018 at 1847 UTC. GPM's Microwave

Modeling Landslide Threats in Near Realtime

Modeling Landslide Threats in Near Realtime
Thursday, March 22, 2018
For the first time, scientists can look at landslide threats anywhere around the world in near real-time, thanks to satellite data and a new model developed by NASA. The model, developed at NASA's Goddard Space Flight Center in Greenbelt, Maryland, estimates potential landslide activity triggered by rainfall. Rainfall is the most widespread trigger of landslides around the world. If conditions beneath Earth's surface are already unstable, heavy rains act as the last straw that causes mud, rocks or debris — or all combined — to move rapidly down mountains and hillsides. A new model has been...

GPM Sees Fourth Nor'easter of 2018

GPM Sees Fourth Nor'easter of 2018
More than 90,000 customers were without power overnight after another major nor’easter — the fourth in three weeks — pummeled areas of the U.S. east coast with as much as 19 inches of snow on the first full day of spring. GPM collected this precipitation data as it flew over the storm the evening of Wednesday March 21st, 2018 at 6:04pm ET.

GPM Gets Flake-y
Wednesday, March 21, 2018
In this video GPM Project Scientist Dr. Gail Skofronick-Jackson explains how scientists can measure the size, shape and distribution of snow particles, layer by layer, in a storm using GPM. The Global Precipitation Measurement mission is an international satellite project that provides next-generation observations of rain and snow worldwide every three hours.

Tropical Cyclone Eliakim's Deadly Rainfall

Tropical Cyclone Eliakim's Deadly Rainfall
Tropical cyclone ELIAKIMS's heavy rainfall caused flooding and landslides over eastern Madagascar that resulted in at least seven deaths. ELIAKIM came less than two weeks after another tropical cyclone called Dumazile passed close to Madagascar. ELIAKIM maintained but didn't exceed tropical storm intensity as it battered Madagascar. ELIAKIM's slower movement as it passed over the island nation caused continuous heavy rainfall over northeastern Madagascar. Tropical cyclone ELIAKIM has now moved back into the Indian Ocean and is moving toward the southeast and away from Madagascar. This rainfall

GPM Sees Tropical Cyclone Eliakim Forming, Threatening Madagascar

GPM Sees Tropical Cyclone Eliakim Forming, Threatening Madagascar
The Joint Typhoon Warning Center (JTWC) issued it's first warning for tropical cyclone ELIAKIM on March 15, 2018 at 0300 UTC as the tropical cyclone moved closer to the northeastern tip of Madagascar. It's maximum sustained wind speeds had increased to 50 kts (57.5 mph) by March 15, 1200 UTC. Forming tropical cyclone ELIAKIM was shown with improved organization when the GPM core observatory satellite flew above on March 14, 2018 at 1356 UTC. GPM's Dual Frequency Precipitation Radar (DPR) data revealed that intense convective storms were occurring in the northwest quadrant of the forming

Forming Tropical Cyclone Near Madagascar Inspected By GPM

Forming Tropical Cyclone Near Madagascar Inspected By GPM
A new tropical cyclone may affect Madagascar in a few days. The Joint Typhoon Warning Center (JTWC) has been keeping an eye on an area of convection in the Indian Ocean northeast of Madagascar. A circulation center has already been observed. Environmental conditions are favorable for the birth of a tropical cyclone in that area with the presence of low vertical wind shear and warm sea surface temperatures. Tropical cyclone AVA caused many deaths in January when it's heavy rains caused extensive flooding in Madagascar. Tropical cyclone DUMAZILE also caused extensive flooding less than two weeks

GPM Views Snow in Third Nor'easter of 2018

GPM Views Snow Third Nor'easter of 2018
The GPM Core Observatory satellite flew over a powerful winter storm early on the morning of Tuesday March 13th, 2018, the third such "Nor'easter" to hit the U.S. east coast this year. GPM's Dual-frequency Precipitation Radar took 3D measurements as it flew over the storm, which show the boundary between liquid (green / yellow / red) and frozen (blue) precipitation. The storm is expected to last through most of Tuesday, disrupting road and air travel. Image and caption by Jacob Reed (Telophase / NASA GSFC
