GPM Takes Parting Look At Hermine

GPM Takes Parting Look At Hermine
Post Tropical Cyclone Hermine was still rotating in the Atlantic Ocean east of New Jersey when the the GPM core observatory satellite flew above on September 6, 2016 at 2:05 PM EDT ( 1806 UTC). Hermine's power was greatly dissipated from the hurricane that hit Florida on September 2, 2016. Hermine still had maximum sustained winds of about 58 mph (50 kts). Hermine was also still producing some light to moderate showers. Precipitation data shown here were derived from GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments. Those data showed that rain was falling

GPM Sees Hermine's Twin Towers

NASA Sees Hermine's Twin Towers
Friday, September 2, 2016
In order for Hermine or any other tropical depression, to intensify there must be a pathway for heat energy from the ocean surface to enter the atmosphere. For Hermine, the conduit may have been one of the two "hot towers" that the Global Precipitation Measurement mission or GPM core satellite observed on Aug. 31 at 4:09 p.m. EDT (2009 UTC). GPM's DPR instrument saw strong storms near the center of Tropical Depression Hermine on the evening of Aug. 31. Two "hot towers" are seen to the right of the low pressure center (south and east of the center), which are labeled "T1" and "T2." The "L"...

GPM Sees Increasingly Organized Tropical Storm Hermine

GPM Sees Increasingly Organized Tropical Storm Hermine
Tropical Depression Nine was upgraded to Tropical Storm Hermine on Wednesday August 31, 2016 at 2 PM EDT (1800 UTC). The GPM core observatory satellite passed directly above newly designated tropical storm Hermine on August 31, 2016 at 4:06 PM EDT (20:06 UTC). Rainfall data derived from GPM's Microwave (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed that precipitation intensity had increased and moved into western Florida. Rainfall measured by GPM's DPR had increased to a rate of over 9.9 inches (251 mm) per hour in very powerful storms in the Gulf Of Mexico northwest of

Intensifying Tropical Depression Nine Checked By GPM

Intensifying Tropical Depression Nine Checked By GPM
The National Hurricane Center (NHC) expects Tropical Depression Nine to intensify over the next day or so. Vertical wind shear is predicted to be low and the tropical depression is moving over warmer water. Both of these factors will provide fuel for intensification. The GPM core observatory satellite scanned the tropical depression on August 31, 2016 at 2:46 AM EDT (0646 UTC). GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments saw heavy rainfall in strong convective storms in the Gulf Of Mexico northwest of Cuba. GPM's DPR found that some of these intense

GPM Views Hurricane Gaston Eye Wall Replacement

GPM Views Hurricane Gaston Eye Wall Replacement
Hurricane Gaston was located in the central Atlantic Ocean west of Bermuda when the GPM core observatory satellite passed over on August 30, 2016 at 00:31 AM EDT (0431 UTC). Gaston was a category two on the Saffir-Simpson hurricane wind scale with maximum sustained winds of about 103.5 mph (90 kts). GPM happened to fly over as Gaston was undergoing an eye wall replacement. Intense rainfall was clearly shown by GPM in rain bands of both the inner and the outer replacement eye walls. Precipitation was calculated from data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation

Tropical Depression Nine Forms

Tropical Depression Nine Forms
The frequency of tropical cyclone formation has definitely increased in the Atlantic Ocean basin. A tropical wave that the National Hurricane Center (NHC) had been monitoring for development since it left the African coast almost two weeks ago was upgraded to Tropical Depression Nine (TD09L) on August 28, 2016. The low pressure became a little better organized after moving into the Florida Strait and that led to the upgrade. The GPM core observatory satellite passed above the still relatively poorly organized tropical depression on August 29, 2016 at 2:56 AM EDT (0656 UTC). Maximum sustained

GPM Examines Tropical Storm Lester

GPM Examines Tropical Storm Lester
Lester became the 12rd named storm of the 2016 eastern Pacific Ocean hurricane today. Lester was far away from the Mexican coast early today and headed toward the west-northwest. Low vertical wind shear and warm sea surface temperatures are expected to assist Lester's intensification to hurricane status tomorrow. Tropical storm Lester had wind speeds of about 35 kts (40 mph) when the GPM core observatory satellite passed over on August 25, 2016 at 1026 UTC. Data from GPM satellite's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed that Lester was getting

Gaston Hovers Around Hurricane Intensity as it Moves into the Central Atlantic

Gaston Hovers Around Hurricane Intensity as it Moves into the Central Atlantic
Gaston became the 3rd hurricane of the season early this morning (just after midnight EDT) as the storm was moving northwestward into the Central Atlantic about midway between the Leeward Islands and the Cape Verde Islands before weakening back into a tropical storm less than 12 hours later. Gaston is continuing to battle relatively strong environmental wind shear brought about by an upper-level low pressure center positioned to the west of Gaston. Winds flowing counter-clockwise around the upper low are blowing from the southwest while Gaston is moving northwest. These opposing winds are

GPM Examines Threatening Tropical Disturbance

GPM Examines Threatening Tropical Disturbance
On August 25, 2016 at 0716 UTC (3:16 AM EDT) the GPM core observatory satellite had an excellent look at an area of low pressure associated with a tropical wave moving past the northern Dominican Republic. The National Hurricane Center (NHC) has been monitoring this area of disturbed weather for potential development into a tropical cyclone. This low is predicted by the NHC to produce heavy rainfall as it continues moving toward the northeast. The development of a tropical storm or hurricane moving in this direction could pose future danger to the Bahamas and the southeastern United States
