Intensifying Tropical Cyclone Francis Inspected By GPM

Intensifying Tropical Cyclone Francis Inspected By GPM
Tropical cyclone Francis formed north of Melville Island, Australia on April 27, 2017. Francis has been gradually intensifying while moving south-southwestward through the Timor Sea. Francis had maximum sustained winds estimated at 50 kts (57.5 mph) when the GPM core Observatory flew over on April 27, 2017 at 1936 UTC. The rainfall analysis shown here used data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments. DPR data indicated that strong convective storms near the center of the tropical storm were dropping rain at a rate of over 70 mm (2.8

Tropical Depression 03W In The Pacific Examined By GPM

Tropical Depression 03W In The Pacific Examined By GPM
Tropical Depression 03W formed in the Pacific Ocean west of Guam on April 24, 2017. The GPM core observatory satellite had an excellent view of TD03W when it flew over on April 14, 2017 at 1901 UTC. The GPM satellite found that the newly formed tropical depression contained some very powerful convective storms. Intense storms in the middle of the organizing convective cluster were dropping precipitation at extreme rates. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments unveiled tall convective storm towers on the eastern side of this cluster of storms that

Arlene Becomes Rare Atlantic Tropical Cyclone

Arlene Becomes Rare Atlantic Tropical Cyclone
Tropical storms are quite rare in the Atlantic at this time of the year, which is why the formation of Tropical Storm Arlene in the north Central Atlantic yesterday, Thursday April 20th at 5:00 pm EDT, was so unusual. The National Hurricane Center (NHC) noted that Arlene became only the 2nd tropical storm to form in the Atlantic during the month of April in the entire satellite era, the other being Tropical Storm Ana back in 2003. GPM captured this timely image of Arlene just after the NHC officially designated it to be a tropical storm. The image was taken at 21:56 UTC (5:56 pm EDT) on

GPM Sees the Formation of Early Atlantic Ocean Tropical Depression 1

NASA Sees the Formation of Early Atlantic Ocean Tropical Depression 1
A low pressure area in the Atlantic Ocean, located southwest of the Azores was designated as Subtropical Depression One on April 19 as NASA examined its rainfall. By April 20 it had become the Atlantic's first tropical depression. Just as the subtropical depression was forming in the North Atlantic Ocean on April 19 at 11 a.m. EDT (1500 UTC) the Global Precipitation Measurement Mission or GPM core observatory satellite flew directly over it and identified areas where rainfall was heaviest in the system. Data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR)

GPM Sees Tropical Cyclone Maarutha Develop

GPM Sees Tropical Cyclone Maarutha Develop
Tropical Storm Maarutha became the first tropical cyclone of 2017 in the Bay of Bengal when it formed on April 15, 2017. Maarutha intensified slightly as it moved northeastward toward Burma (Myanmar). Maarutha reached it's maximum sustained wind speed of 45 kts (52 mph) over the open waters of the Bay Of Bengal. The GPM core observatory satellite had a good view of the forming tropical cyclone on April 14, 2017 at 0121 UTC when it was in the Bay Of Bengal west of the Andaman Islands. GPM had another excellent view just before the organizing tropical cyclone was designated tropical storm

New Zealand's Extreme Rainfall Examined With IMERG

New Zealand's Extreme Rainfall Examined With IMERG
Two extra-tropical cyclones recently dropped very heavy rain over New Zealand. Tropical cyclone Debbie dumped extreme amounts of rain over the northeastern coast of Australia when it hit the Queensland coast on March 28, 2017. After drenching northeastern Australia Extra-tropical Cyclone Debbie transported a river of water over New Zealand last week. Debbie's remnants dropped heavy rainfall that caused widespread flooding near the Bay of Plenty on New Zealand's northeastern coast. Thousands of residents needed to be evacuated with extra-tropical cyclone Debbie. This week extra-tropical cyclone

Change in IMERG early 2/5/2017-3/12/2017

During the initial setup up for V04 IMERG, an error was made in the configuration for running the EARLY version of IMERG. This affected the V04A early data from Feb 5 - March 12, 2017. This error caused the early and the late products to be identical. Given that the LATE product is the more accurate product this might not be an issue for many users. However, users who need a consistent approach in the early data will need to download IMERG early Feb 5-March 12, 2017 again. On April 12, 2017 at about 16:55 UTC Feb 5-Feb 28, 2017 files have been rerun and are available from their usual location

Texas' Heavy Rain Measured By IMERG

Texas' Heavy Rain Measured By IMERG
Over the past few days a slow moving frontal system moving through the Southwest produced heavy rain resulting in flooding and mudslides over central Texas. One person was reported swept away by flood water near Fort Hood Texas. NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG) data were used to provide an estimate of rainfall accumulation over Texas. From April 10-12, 2017 IMERG estimates indicate that over 8 inches (203 mm) of rain fell in the area from central Texas through northern Louisiana.

GPM Catches Nor'easter over New England

At the time of the Global Precipitation Measurement (GPM) Core Observatory overpass (April 1, 2017, 0550 UTC), the storm's center of low pressure was south of Long Island. At the mid-levels of the atmosphere, the circulation was centered over northeast Pennsylvania. This led to a classic overrunning, warm conveyor setup, which happened when the counterclockwise low level flow drew in cold air out of the north/northeast (hence "Nor'easter") from Canada.

At the time of the Global Precipitation Measurement (GPM) Core Observatory overpass (April 1, 2017, 0550 UTC), the storm's center of low pressure was south of Long Island. At the mid-levels of the atmosphere, the circulation was centered over northeast Pennsylvania. This led to a classic overrunning, warm conveyor setup, which happened when the counterclockwise low level flow drew in cold air out of the north/northeast (hence "Nor'easter") from Canada. Higher up, warm and moist air from further south was lifted over this cold air and resulted in precipitation in the form of snow at the surface...
