Tropical Storm 14W Examined By The GPM Satellite

Tropical Storm 14W Examined By The GPM Satellite
Tropical storm 14W formed in a remote area of the western Pacific Ocean southeast of Wake Island on August 11, 2017. The GPM core observatory satellite flew above the center of the newly formed tropical storm on August 11, 2017 at 0902 UTC. The "core" satellite carries advanced radar and radiometer systems that measure precipitation from space and serves as a standard that is used to unify precipitation measurements from a constellation of research and operational satellites. Tropical storm 14W was revealed by GPM to be small but well organized with very intense convective storms near the

More Organized Tropical Storm Gert's Rainfall Examined by GPM

More Organized Tropical Storm Gert's Rainfall Examined by GPM
The GPM core observatory satellite passed above tropical storm Gert on August 14, 2017 at 9:36 EDT (1336 UTC) when winds had reached about 57.5 mph (50 kts). Data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments were used to show the coverage and the intensity of rainfall arround tropical storm Gert. The area covered by GPM's radar swath (shown in lighter shades) revealed that the most intense rainfall, measuring greater than 3.5 inches (90 mm) per hour, was located in bands of rain on the eastern side of the storm. This GPM pass was mentioned

GPM Sees Gert Approaching Hurricane Intensity

GPM Sees Gert Approaching Hurricane Intensity
Tropical storm Gert was upgraded to a Hurricane on 1100 PM EDT Monday August 14, 2017 at 11:00 PM (August 15, 2017 0300 UTC). The GPM core observatory satellite flew over the intensifying tropical storm on August 14, 2017 at 7:21 PM EDT (2321 UTC). With winds of about 69 mph (60 kts) Gert was getting close to hurricane intensity. Data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed heavy rainfall south of Gert's partial eye. GMI showed that rain was falling at a rate of over 1.6 inches (40 mm) in that area. GPM's Radar scanned through

GPM Sees Franklin Becoming A Hurricane

GPM Sees Franklin Becoming A Hurricane
As expected, tropical storm Franklin intensified and was upgraded to hurricane Franklin in the afternoon of August 9, 2017. Franklin made landfall on the coast of eastern Mexico early this morning as a category 1 hurricane with winds of over 86 mph (75 kts). Heavy rainfall, flash floods and mudslides are expected as Franklin moves inland and weakens. The remnants of Franklin may survive the transit over Mexico's rough terrain and revive after moving into the eastern Pacific Ocean. The GPM core observatory satellite saw tropical storm Franklin with winds of about 69 mph (60 kts) as it was

Replacement GPM Gridded Text Products

For V05 we produced a daily gridded text product for precipitation data from the core satellite and from the partner constellation imagers. We also produced a monthly rollup of these gridded text products. They were all designated with the product version V05A. If you downloaded these products, we regret to inform you that we found an error in the calculation of convection rate and frozen rate. While the mean precipitation rate values were correct in V05A, convective and frozen rates were erroneous. We have made the necessary changes to the code that produces these products. After extensive

GPM Sees Intensifying Tropical Storm Franklin

GPM Sees Intensifying Tropical Storm Franklin
The GPM core observatory satellite had an informative pass over Tropical storm Franklin on August 9, 2017 at 0302 UTC. The intensifying tropical storm had moved from Mexico's Yucatan Peninsula into the southwestern Gulf Of Mexico's Bay of Campeche. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) data showed that Franklin contained a few heavy bands of convective rainfall. GPM's DPR found rain falling at a rate of over rain 2.4 inches (62 mm) per hour in bands of intense storms moving around the southwestern side of the storm. This 3-D view of tropical storm Franklin

Hilary And Irwin Interaction Shown

Hilary And Irwin Interaction Shown
Tropical cyclone development in the eastern Pacific Ocean has been occurring at a slightly above normal pace this year. Hurricanes Hilary and Irwin were the two most recently named tropical cyclones to form in this area. These two were a little unusual because they traveled so close to each other that an interaction occurred that radically changed the direction and speed of tropical storm Irwin's movement. The Fujiwara effect happens when cyclones move close of one another. Their centers will sometimes begin orbiting cyclonically (in the northern hemisphere) about a point between the two

GPM Catches a Look at a Rare Tornadic Storm Near the Chesapeake Bay

GPM Catches a Look at a Rare Tornadic Storm Near the Chesapeake Bay
Tornadic storms in Maryland are rare to begin with, let alone in the middle of the night. However, about an hour after midnight in the early morning hours of Monday April 24th at around 1:00 am local time, a severe thunderstorm, which was located at the southern end of a mass of storms and which had just dumped heavy rains over the Washington, DC area, began to cross the Chesapeake Bay near Annapolis, Maryland heading eastward. It is quite common for storms to weaken as they cross the cooler waters of the Bay, but water temperatures are now rather warm, over 80F, which allowed the storm to

A New Multi-dimensional View of a Hurricane

A New Multi-dimensional View of a Hurricane
Wednesday, July 26, 2017
Download in high resolution from the NASA Goddard Scientific Visualization Studio NASA researchers now can use a combination of satellite observations to re-create multi-dimensional pictures of hurricanes and other major storms in order to study complex atmospheric interactions. In this video, they applied those techniques to Hurricane Matthew. When it occurred in the fall of 2016, Matthew was the first Category 5 Atlantic hurricane in almost ten years. Its torrential rains and winds caused significant damage and loss of life as it coursed through the Caribbean and up along the southern U.S...
