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
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

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

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

Intensifying Tropical Storm Jose

On September 5, 2017 tropical Storm Jose became the tenth named storm of the Atlantic hurricane season. The GPM core observatory satellite passed above the intensifying tropical cyclone on September 6, 2017 at 00:45 AM AST (0435 UTC). Data collected by GPM's Microwave Imager (GMI) at that time showed that weak bands of rain were starting to develop around Jose's center of circulation. GPM's Dual-Frequency Precipitation Radar (DPR) data swath revealed the location of heavy rain in a feeder band on Jose's western side. DPR found that rain in this area was falling at a rate of over 5.3 inches

GPM Satellite Probes Dangerous Category Five Hurricane Irma

The GPM core observatory satellite had an exceptional view of hurricane Irma's eye when it flew above on September 5, 2017 at 12:52 PM AST (1652 UTC). This image 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. GPM's DPR (shown in lighter shades) uncloaked
Hurricane Irma's Heat Engine Exposed
At 1 PM EDT (1700 UTC) on September 5, 2017, the radar on the Global Precipitation Measuring Mission (GPM) satellite captured this 3D view of the heat engine inside of category-5 Hurricane Irma. Under the central ring of clouds that circles the eye, water that had evaporated from the ocean surface condenses, releases heat, and powers the circling winds of the hurricane. The radar on the GPM satellite is able to estimate how much water is falling as precipitation inside of the hurricane, which serves as a guide to how much energy is being released inside the hurricane's central "heat engine."...

GPM Sees Potential Tropical Depression Developing In The Gulf Of Mexico

The GPM Core Observatory satellite had an excellent view of a potential tropical depression developing in the Gulf Of Mexico on September 5, 2017 at 3:34 AM CDT (0834 UTC). GPM found that powerful convective storms were dropping heavy rainfall in the Gulf of Mexico east Mexico's coast. GPM's Dual-Frequency Precipitation Radar (DPR) instrument measured rain falling at a rate of over 9.2 inches (233 mm) per hour in an intense band of storms. GPM's Radar (DPR Ku Band) data was used to examine the 3-D structure of precipitation in this area of strong convective storms. GPM's DPR showed that storm
GPM Captures Hurricane Harvey's Rainfall
Music: "Whirlpool," Michael Jan Levine, Killer Tracks The Global Precipitation Measurement (GPM) Core Observatory captured these images of Hurricane Harvey at 11:45 UTC and 21:25 UTC on the 27th of August nearly two days after the storm made landfall as it was meandering slowly southeast at just 2 mph (~4 kph) near Victoria, Texas west of Houston. The image shows rain rates derived from GPM's GMI microwave imager (outer swath) and dual-frequency precipitation radar or DPR (inner swath) overlaid on enhanced visible/infrared data from the GOES-East satellite. Harvey's cyclonic circulation is...
