GPM Sees Potential Tropical Depression Developing In The Gulf Of Mexico

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

GPM Captures Hurricane Harvey's Rainfall
Friday, September 1, 2017
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...

Intensifying Hurricane Irma Checked By GPM Satellite

Intensifying Hurricane Irma Checked By GPM Satellite
After forming in the eastern Atlantic Ocean on Wednesday tropical storm Irma strengthened and became a powerful category three hurricane on Thursday August 31, 2017. Hurricane Irma was moving west-northwestward with winds of about 115 mph (100 kts) when the GPM core Observatory satellite saw it on September 1, 2017 at 1:47 AM AST (0547 UTC). Data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed the locations and intensity of heavy precipitation within the hurricane. GPM's Radar (DPR Ku band) found that a powerful convective storm in a

GPM Satellite Sees Tropical Storm Irma Forming Near Cape Verde Islands

GPM Satellite Sees Tropical Storm Irma Forming Near Cape Verde Islands
The National Hurricane Center (NHC) upgraded a low pressure area in the far eastern Atlantic Ocean to tropical storm Irma on August 30, 2017 at 11:00 AM AST (1500 UTC). Tropical cyclones that form in that part of the Atlantic Ocean are often the largest and most powerful hurricanes of the season. Hurricanes Ivan (2004), Isabel (2003), Hugo (1989) and Allen (1980) are examples of past powerful hurricanes that formed near the Cape Verde islands. The GPM core observatory satellite flew above forming tropical storm Irma on August 30, 2017 at 1:56 AM EDT (0556 UTC). This new tropical cyclone was

NASA's IMERG Shows Rainfall Accumulation Along Harvey's Track

NASA's IMERG Shows Rainfall Accumulation Along Harvey's Track
Total rainfall estimates from NASA's Integrated Multi-satelliE Retrievals for GPM (IMERG) data are shown here for the period from August 23-29, 2017. During this period hurricane Harvey dropped heavy rainfall as it moved through the Gulf Of Mexico and stalled over Texas. It has been reported that Harvey dropped over 40 inches (1016 mm) of rain over southeastern Texas during this period. Hurricane Harvey's locations and track are shown here overlaid in white IMERG Data are produced using data from the satellites in the GPM Constellation, and is calibrated with measurements from the GPM Core
