A weather system moving slowly westward through the northwestern Hawaiian Islands has caused destructive flooding and mudslides and NASA's Global Precipitation Measurement mission or GPM satellite analyzed the heavy rainfall.
Southwest Research Institute scientists posit a violent birth of the tiny Martian moons Phobos and Deimos, but on a much smaller scale than the giant impact thought to have resulted in the Earth-moon system. Their work shows that an impact between proto-Mars and a dwarf-planet-sized object likely produced the two moons, as detailed in a paper published today in Science Advances.
On Sunday, April 15, 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.
When tested on their knowledge of 23 types of weather information, from icing forecasts and turbulence reports to radar, 204 general aviation (GA) pilots surveyed by Embry-Riddle Aeronautical University researchers were stumped by about 42 percent of the questions. The findings, published in the April 2018 edition of the International Journal of Aerospace Psychology, are worrisome. Embry-Riddle's Elizabeth Blickensderfer said, 'We have got to improve how weather information is displayed.'
With much of the central plains and Midwest now entering peak tornado season, the impact of these potentially devastating weather events will be shaped in large part by how individuals think about and prepare for them. A new study published in Risk Analysis: An International Journal shows that people's past experiences with tornadoes inform how they approach this type of extreme weather in the future, including their perception of the risk.
An Earth observation satellite, called TanSat, has produced its first global carbon dioxide maps. TanSat was launched by a collaborative team of researchers in China, and these maps are the first steps for the satellite to provide global carbon dioxide measurements for future climate change research.
The remnant low pressure area that was once Tropical Cyclone Iris continues to linger in the South Pacific Ocean. NASA's Aqua satellite passed over the system and captured a visible image of it.
As expected, Tropical Cyclone Keni followed a track similar to Tropical Cyclone Josie and passed to the southwest of Fiji's main island of Viti Levu on April 10, 2018 (UTC).
NASA satellite imagery showed that Tropical Cyclone Keni was being battered by vertical wind shear. NASA-NOAA's Suomi NPP satellite revealed that wind shear was pushing the clouds and storms associated with Keni to the southeast of the center.
Satellite imagery showed that the former tropical cyclone known as Iris appeared better organized and more circular.
