A New Multi-dimensional View of a Hurricane
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...

Deadly Hurricane Matthew's Total Rainfall

Hurricane Matthew devastated western Haiti and killed over 1,000 people. Matthew also took the lives of at least 37 deaths in the United States with 18 deaths occurring in the state of North Carolina. Flooding is still widespread in North Carolina. Some rivers in North Carolina such as the Tar and the Neuse are still rising. This rainfall analysis was accomplished using data from NASA's Integrated Multi-satelliE Retrievals for GPM (IMERG). IMERG is a unified U.S. algorithm that provides a multi-satellite precipitation product. IMERG is run twice in near-real time with the “Early” multi

Matthew Brings Heavy Rains, Destruction to Parts of the Northern Caribbean

Matthew began as a fairly impressive tropical wave that emerged off of the coast of Africa on the 23rd of September but had to make its way all the way across the Central Atlantic before finally organizing into a tropical storm on the morning of the 28th while passing through the Windward Islands. Matthew then slowly but steadily intensified into a minimal hurricane by the early afternoon of the following day as it continued to track westward through the central eastern Caribbean. The next day, September 30th, Matthew underwent a period of rapid intensification; its winds increased in
GPM Sees Hurricane Matthew Nearing Florida
UPDATE 10/6/16: NASA's Global Precipitation Measurement mission or GPM core observatory satellite flew over Hurricane Matthew several times as the category 4 storm headed toward Florida. The GPM Core Observatory carries two instruments that show the location and intensity of rain and snow, which defines a crucial part of the storm structure – and how it will behave. The GPM Microwave Imager sees through the tops of clouds to observe how much and where precipitation occurs, and the Dual-frequency Precipitation Radar observes precise details of precipitation in 3-dimensions. This data...

GPM Sees Hurricane Matthew Producing Dangerous Rainfall

The GPM core observatory satellite passed above hurricane Matthew on October 2, 2016 at 5:46 AM EDT (0946 UTC). GPM’s Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments collected data that were used in the rainfall map shown here. GPM found that very heavy rainfall was located around Matthew. Rain was revealed by GPM falling at a rate of over 6.4 inches (163 mm) in some areas near hurricane Matthew. Of particular interest is an area of very heavy rain located well to the east of Hurricane Matthew’s center. This blob of strong convective storms has been persistent

GPM Finds Intense Rainfall In Matthew Rainband

Matthew rapidly intensified Thursday evening and winds increased to 100 kts (115 mph) by Friday September 30, 2016. The GPM core observatory satellite flew over Hurricane Matthew on September 20, 2016 at 0946Z (5:46 AM EDT). A rainfall analysis from GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) showed that the Matthew had heavy rainfall in the northern side of the newly formed eye wall. GPM’s radar area of coverage (shown in a higher shade) included a very intense feeder band on the southeastern side of the hurricane. DPR measured rain falling at a rate of greater

Tropical Storm Matthew Forms Over the Windward Isles, Enters the Caribbean

A fairly strong tropical wave that had been making its way westward across the Central Atlantic over the past several days has now finally organized itself into a tropical storm, Tropical Storm Matthew, the 13th named storm of the season, while passing through the Windward Islands. The storm is poised to intensify as it enters the eastern Caribbean. The tropical wave leading to Matthew's formation emerged off of the coast of Africa back on the 23rd of September. However, despite having a robust level of convective thunderstorm activity, the wave did not acquire a closed low-level circulation
