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

http://www.nhc.noaa.gov/
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

GPM Sees Hurricane Matthew Nearing Florida
Wednesday, October 5, 2016
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

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

Intensifying Typhoon Chaba Examined By GPM

Intensifying Typhoon Chaba Examined By GPM
As Typhoon Chaba moved to the western Pacific Ocean south of Okinawa over the past few days wind speeds have increased to 115 kts (132 mph).The GPM core observatory satellite flew directly above Chaba’s eye on October 2, 2016 at 2026 UTC. GPM’s Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed that Chaba was dropping extremely heavy precipitation. Some precipitation in the typhoon’s small eye wall was measured by GPM’s radar falling at a rate of more than 234 mm (9,2 inches) per hour. GPM’s Radar (DPR Ku Band) data were used to show the 3-D shape of

GPM Finds Intense Rainfall In Matthew Rainband

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

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

This visualization begins with an overview of the United States showing the clouds and rainfall accumulation of the massive rain event over Louisiana beginning on August 11th, 2016 through August 13th, 2016. The camera then begins to zoom in as time resets to August 11th. Time then slows way down on August 12th to show the first of GPM's passes. In this close up of GPM's volumetric DPR data over Louisiana, a cutting plane materializes into view to show the inner structure of this giant storm system.

GPM Gets a Closer Look at Louisiana Floods

GPM Provides a Closer Look at the Louisiana Floods
Thursday, September 29, 2016
Twice on August 12, 2016 GPM flew over a massive rainstorm that flooded large portions of Louisiana. The flooding was some of the worst ever in the state, resulting in a state of emergency. Tens of thousands of people were evacuated from their homes in the wake of this unprecedented event. Throughout the course of August 12 (UTC) GPM captured the internal structure of the storm twice and GPM IMERG measured the rainfall accumulation on the ground. NASA's GPM satellite is designed to measure rainfall using both passive microwave (GMI) and radar (DPR) instruments. DPR can observe 3D structures of...

GPM Finds Heavy Rain In Tropical Storm Ulika

GPM Finds Heavy Rain In Tropical Storm Ulika
The GPM core observatory satellite had a good early morning look at newly formed tropical storm Ulika on September 27, 2016 at 5:26 AM HST (1526 UTC). Ulika was located in the central Pacific Ocean less than 975 nautical miles east-southeast of Hilo, Hawaii. GPM found that Ulika contained some very powerful convective storms and a well defined center of circulation. GPM's Dual-Frequency Precipitation Radar (DPR) discovered that some strong convective storms inside the tropical storm were dropping precipitation at a rate of over 187 mm (7.4 inches) per hour.
