NASA’s Global Precipitation Measurement satellite monitors Eastern United States Storms, Tornadoes

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – On Sunday April 15th, 2018 a line of strong storms at one point stretched from the Florida Straits below the Florida Keys all the way up the East Coast and into Ohio. The Global Precipitation Measurement mission or GPM core satellite analyzed the severe storms as it passed overhead. GPM is a joint mission between NASA and the Japan Aerospace Exploration Agency, JAXA.

Many of the storms were strong with wide spread reports of wind damage from north Florida up through the Carolinas and into central Virginia.

GPM captured an image of the advancing line of storms on April 16 at 00:17 UTC (8:17 pm EDT, April 15). GPM showed a narrow leading line of thunderstorms producing heavy rain rates (orange and red areas), followed by a much broader area of light to moderate rain (blue and lighter green areas).

NASA to launch Two Satellites focused on studying Earth’s Frozen Areas

 

Written by Patrick Lynch

NASA - National Aeronautics and Space AdministrationWashington, D.C. – In 2018, NASA will intensify its focus on one of the most critical but remote parts of our changing planet with the launch of two new satellite missions and an array of airborne campaigns.

The space agency is launching these missions at a time when decades of observations from the ground, air, and space have revealed signs of change in Earth’s ice sheets, sea ice, glaciers, snow cover and permafrost. Collectively, scientists call these frozen regions of our planet the “cryosphere.”

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA engineer Manuel Vega can see one of the Olympic ski jump towers from the rooftop of the South Korean weather office where he is stationed. Vega is not watching skiers take flight, preparing for the 2018 PyeongChang Winter Olympics and Paralympic games.

Instead, he’s inspecting the SUV-sized radar beside him. The instrument is one of 11 NASA instruments specially transported to the Olympics to measure the quantity and type of snow falling on the slopes, tracks and halfpipes.

NASA studies effects of Dust, Warm Weather on Melting Snow and Spring Runoff

 

Written by Carol Rasmussen
NASA’s Earth Science News Team

NASA - National Aeronautics and Space AdministrationWashington, D.C. – A new study has found that dust, not spring warmth, controls the pace of spring snowmelt that feeds the headwaters of the Colorado River. Contrary to conventional wisdom, the amount of dust on the mountain snowpack controls how fast the Colorado Basin’s rivers rise in the spring regardless of air temperature, with more dust correlated with faster spring runoff and higher peak flows.

The finding is valuable for western water managers and advances our understanding of how freshwater resources, in the form of snow and ice, will respond to warming temperatures in the future.
