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

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

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)
Storm Brings Heavy Precipitation to Northeast
UPDATE 1/23/2016 5:00pm ET On January 23, 2016 at 1239 UTC (7:39 AM EST) the GPM core observatory passed above the deadly winter storm that was burying the Northeast under a deep layer of snow. As GPM passed above a band of snow was shown approaching the island of Manhattan. The winter storm was predicted to dump near record snowfall in New York city. GPM's Microwave Imager (GMI) and Dual-frequency Precipitation Radar (DPR) instruments showed massive amounts of moisture being transported from the Atlantic Ocean over states from New York westward through West Virginia. GPM's Radar instruments...

Developing Tropical Cyclone Viewed By GPM

The GPM core observatory satellite saw a tropical cyclone developing in the South Indian Ocean east of Madagascar on January 21, 2016 at 0146 UTC. GPM's Microwave Imager (GMI) and Dual-frequency Precipitation Radar (DPR) measured precipitation in the potential tropical cyclone. The most intense showers were shown by the GMI instrument to be dropping rain at a rate of over 71 mm (2.8 inches) per hour in strong storms to the northeast of the tropical low's center of circulation. GPM's radar (DPR) viewed a swath of data to the west of the developing tropical cyclone center where rain was measured
