GPM Satellite Looks At Hurricane Maria's Rainfall

GPM Satellite Looks At Hurricane Maria's Rainfall
Early this morning (after 6 AM local time) hurricane Maria made landfall near Yabucoa, Puerto Rico as a strong category four hurricane. Maximum sustained winds in the hurricane were reported to be 149.5 mph (130 kts) as Maria moved toward San Juan, Puerto Rico. Powerful convective storms within the hurricane were also dropping heavy rainfall. The GPM core observatory satellite collected data as it passed above hurricane Maria earlier on September 19, 2017 at 9:51 PM AST (September 20, 2017 0151 UTC). This rainfall analysis was derived from GPM's Microwave Imager (GMI) and Dual-Frequency

Jose Continues to Meander off the East Coast

Jose Continues to Meander off the East Coast
Jose has been a named storm for nearly two weeks now as it continues to slowly move northward off the US East Coast east of the Outer Banks of North Carolina. At one time, Jose was a powerful category 4 border line category 5 storm with maximum sustained winds reported at 155 mph by the National Hurricane Center back on the 9th of September as it was approaching the northern Leeward Islands. Jose passed northeast of the Leeward Islands as a category 4 storm on a northwest track and then began to weaken due to the effects of northerly wind shear. Jose then made a counterclockwise loop about

Hurricane Maria Threatening The Leeward Islands

Hurricane Maria Threatening The Leeward Islands
Intensifying hurricane Marie is on a path that is predicted to impact the Leeward Islands. Hurricane Irma caused death and wide spread destruction there less than two weeks ago. Very powerful convective storms and multiple lightning strokes within Maria have been cited as proof that Maria is an energetic intensifying hurricane. The GPM core observatory satellite had an excellent view of hurricane Maria when it passed almost directly above the hurricane on September 17, 2017 at 1001 PM AST (September 18, 2017 0201 UTC).

GPM Sees Hurricane Max Approaching Mexico's Coast

GPM Sees Hurricane Max Approaching Mexico's Coast
Hurricane Max made landfall on Mexico's southern Pacific coast yesterday afternoon. Max was a small hurricane with maximum sustained winds of about 86 mph (75 kts). By this morning wind speeds in the dissipating storm had decreased to about 29 mph (25 kts). Max's dissipating remnants are still expected to produce heavy rain as they continue moving eastward today. The GPM core observatory satellite passed above Hurricane Max on September 14, 2017 at 11:35 AM CDT (1653 UTC) as Max was close to making landfall east of Acapulco, Mexico. Although Max was a small hurricane the GPM satellite's radar

Using Satellites to Predict Malaria Outbreaks

Using NASA Satellite Data to Predict Malaria Outbreaks
Friday, September 15, 2017
In the Peruvian Amazon, the Anopheles darlingi mosquito is most responsible for spreading malaria. With funding from NASA's Applied Sciences Program, scientists are turning to the agency’s fleet of Earth-observing satellites to develop a system that uses satellite and other data to help forecast malaria outbreaks at the household level months in advance and prevent them from happening. Credits: NASA's Goddard Space Flight Center / Joy Ng In the Amazon Rainforest, few animals are as dangerous to humans as mosquitos that transmit malaria. The tropical disease can bring on high fever, headaches...

GPM Examines Typhoon Talim's Large Eye

GPM Examines Typhoon Talim's Large Eye
The GPM cored observatory had another outstanding view of typhoon Talim in the western Pacific Ocean on September 13, 2017 at 1537 utc. A large eye was Talim's most distinctive feature. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) showed the location of intense rainfall within Talim's distinct eye wall. DPR revealed that rain was falling at a rate of over 232 mm (9.13 inches) per hour in convective storms in the western side of the typhoon's eye wall. GPM also showed that rainfall was far weaker to the the east of Talim's center. This dramatic 3-D view of Talim's

GPM Finds Sheared Hurricane Jose Has Very Tall Storms

GPM Finds Sheared Hurricane Jose Has Very Tall Storms
On Wednesday September 13, 2017 at 10:35 AM AST (1435 UTC) the GPM core observatory satellite traveled above persistent hurricane Jose as it was meandering in the Atlantic Ocean. GPM found that even though Jose was affected by strong northwesterly shear it contained very powerful convective storms. GPM's Dual-Frequency Precipitation Radar (DPR) found extremely intense downpours within these storms where rain was measured by DPR falling at a rate of over 8.9 inches (227 mm) per hour. GPM's radar (DPR Ku Band) was used to show a 3-D cross-section of the precipitation within hurricane Jose. This

GPM Examines Hurricane Irma

GPM Examines Hurricane Irma
Wednesday, September 13, 2017
The GPM core observatory satellite had an exceptional view of hurricane Irma's eye when it flew above it on September 5, 2017 at 12:52 PM AST (1652 UTC). This visualization shows a rainfall analysis that was derived from GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) data. Irma was approaching the Leeward Islands with maximum sustained winds of about 178 mph (155 kts). This made Irma a dangerous category five hurricane on the Saffir-Simpson hurricane wind scale. Intense rainfall is shown within Irma's nearly circular eye. This 3-D cross-section through Irma's eye was...

GPM Sees Typhoon Talim Threatening Islands Of Japan

GPM Sees Typhoon Talim Threatening Islands Of Japan
The Joint Typhoon Warning Center (JTWC) predicts that typhoon Kalim in the western Pacific Ocean will intensify and threaten the islands of southern Japan in the the new three days. Environmental conditions such as low vertical wind shear and warm sea surface temperatures are favorable for Talim's intensification. Talim's winds are expected to increase to a peak of 115 kts as it re-curves toward the the Japanese island of Kyushu. The GPM core observatory satellite scanned the western side of typhoon Talim on September 13, 2017 at 0216 UTC. GPM's Microwave Imager (GMI) instrument collected data

Irma’s Heavy Rainfall Measured With GPM IMERG

Irma’s Heavy Rainfall Measured With NASA’s IMERG
Hurricane Irma dropped extremely heavy rain at times during it’s trek from near the Cape Verdi Islands through the northern Leeward islands, Cuba and the southeastern United States. Over 16 inches (406 mm) of rain was reported in Guantanamo, in the easternmost province of Cuba, as the category five hurricane battered the country. Almost 16 inches (406 mm) of rain was also reported at Fort Pierce on the eastern side of Florida. Charleston, South Carolina reported 6 inches (152.4 mm) of rain in 24 hour. This heavy rainfall plus storm surge flooding caused the worst flooding in Charleston since
