Intensifying South Pacific Tropical Cyclone Winston Viewed By GPM

Intensifying South Pacific Tropical Cyclone Winston Viewed By GPM
Tropical cyclone activity has recently increased in the South Pacific Ocean. Four tropical cyclones have formed in this area in 2016. The GPM core observatory satellite had an excellent view of tropical cyclone Winston on February 11, 2016 at 1253 UTC. Winston was located east of Vanuatu with tropical storm force winds of about 55 kts when GPM passed over head. Winston's rainfall was measured by GPM's Microwave Imager (GMI) and Dual-frequency Precipitation Radar (DPR) instruments. GPM's radar data revealed that Winston was dropping rain at a rate of over 60 mm (2.4 inches) per hour on the

GPM Views Tropical Cyclone Forming Near Madagascar

GPM Views Tropical Cyclone Forming Near Madagascar
The GPM core observatory satellite flew over a forming tropical cyclone in the South Indian Ocean between Madagascar and Reunion on February 8, 2016 at 2137 UTC. Low vertical wind shear will assist in the evolution of the tropical low as it moves slowly toward the southwest. Rainfall derived from GPM's Microwave Imager (GMI) and Dual-frequency Precipitation Radar (DPR) data revealed that powerful convective storms near Madagascar's eastern coast were found to be dropping rain at a rate of over 94 mm (3.7 inches) per hour. 3-D measurements were made of convective storm tops with GPM's radar

Intensifying Atlantic Storm Examined By GPM

Intensifying Atlantic Storm Examined By GPM
On February 8, 2016 at 0800 UTC (3 AM EST) the GPM core observatory satellite flew above an intensifying storm in the Atlantic Ocean off the United State's East Coast. This storm is forecast by the National Weather Service (NWS) to bring strong winds, heavy rainfall, and coastal flooding to the Carolina's. Although the center of the storm is well off the coast, bands of precipitation from the storm are also expected to bring heavy snow to eastern New England. A rainfall analysis derived from data collected by GPM's Microwave Imager (GMI) and Dual-frequency Precipitation Radar (DPR) instruments

GPM Examines Violent Thunderstorms in U.S.

GPM Examines Violent Thunderstorms in U.S.
Severe weather moved through the southern U.S. on February 2 and 3, and NASA's Global Precipitation Measurement or GPM core satellite examined the violent thunderstorms. On February 3, 2016 at 1851 UTC (1:51 p.m. EST) the GPM core observatory satellite flew over a line of storms extending from the Gulf coast of Florida through New York state. Tornadoes were spotted in Georgia and South Carolina within this area of violent weather. GPM's Microwave Imager (GMI) and Dual-frequency Precipitation Radar (DPR) instruments measured the precipitation within the area. As the satellite passed above, GPM

Extreme Precipitation Measured From Space

Extreme Precipitation Measured From Space
For over a week the weather over the continental United State's has been punctuated by extreme events. Automobiles were thrown around on January 27, 2016 by tornadoes that hit southern Florida. On January 31 a winter storm with heavy rain, strong winds and isolated thunderstorms hit southern California killing at least one person. There were numerous reports of hail with these storms ranging from pea sized to up to an inch in diameter. Powerful winds with these storms also brought down trees and power lines. A blizzard that followed the Democratic and Republican caucuses in Iowa dropped over

OLYMPEX Successfully Grabs the Rains

OLYMPEX Successfully Grabs the Rains
Friday, January 29, 2016
NASA has finished its campaign to study extreme rain, snow and winds of the Olympic National Forest. Scientists Walt Petersen of NASA Marshall and Robert Houze of the University of Washington narrate this inside look at the Olympic Mountain Experiment (OLYMPEX) field campaign. During the campaign, NASA and its partners gathered precipitation data through both ground and airborne instruments around the Olympic Peninsula in Washington State. They measured the abundance and variety of precipitation including light rain, heavy thunderstorms, and snowfall in the coastal forest. The data collected...

Intensifying Tropical Low Threatens Western Australia

Intensifying Tropical Low Threatens Western Australia
So far this year, no tropical cyclones have formed near Australia. A tropical low is now getting better organized in the Indian Ocean off Australia's northwestern coast. The GPM core observatory flew over this area of disturbed weather on January 27, 2016 at 0946 UTC. GPM's Dual-frequency Precipitation Radar (DPR) instrument measured rain falling at a rate of 96.7 mm (3.8 inches) per hour in towering convective storms within spiraling bands around the tropical low. GPM's Radar (DPR Ku band) made 3-D measurements of convective storm top heights. Some storm tops were found to reach altitudes of

Making Science Fun for Kids Through Comics

Making Science Fun for Kids Through Comics
Wednesday, January 27, 2016
To get young students reading about science, NASA is trying something different. Instead of a press release or a scientific paper, the Global Precipitation Measurement (GPM) mission has launched a Japanese manga-style comic book. GPM, a satellite collaboration between NASA and the Japan Aerospace Exploration Agency, provides global estimates of rain and snow every three hours using advanced instruments. In spring 2013, a GPM Anime Challenge was held for artists from around the world aged 13 years and up to develop an anime-themed character for teaching students about the GPM mission. By...

GPM Flies Over Dissipating Tropical Cyclone Corentin

GPM Flies Over Dissipating Tropical Cyclone Corentin
Tropical cyclone Corentin was the first named tropical cyclone of 2016 in the South Indian Ocean. Corentin caused little danger because it's genesis, maturation and dissipation have all occurred over the South Indian Ocean about equidistant from the distant shores of Madagascar and Australia. The GPM core observatory satellite flew over Tropical Cyclone Corentin on January 25, 2016 at 1306 UTC. High vertical wind shear was starting to take it's toll on the increasingly disorganized tropical cyclone. Rainfall collected by GPM Microwave Imager (GMI) and Dual-frequency Precipitation Radar (DPR)

Potential Upcoming Data Outages Due to Severe Winter Storm

The Washington, DC area is about to get hit with a record-level snow storm, with attendant disruptions to work schedules, travel, communications, and power. If you find that the TMPA-RT products drop out, it is safe to assume that some combination of these effects is preventing production, and we will work to restore service when that is possible.
