With a global average temperature that was three-tenths of a degree Celsius warmer than seasonal norms, 2005 tied with 2002 as the second warmest year in the past 27, according to data gathered by NOAA satellites and processed at The University of Alabama in Huntsville (UAH).
A new way of analyzing data from weather satellites may soon help pilots avoid flying through rain or turbulence from convective thunderstorms, according to a scientist at The University of Alabama in Huntsville.
Cooling rain that precedes some hurricanes as they come on shore may cause those storms to rapidly weaken as they move inland, but that same cooling rain might also cause shallow warm and cold "fronts" within a hurricane system, making it more likely to spin off tornadoes as the storm weakens.
The apparent absence of shadows where shadows were expected to be is raising new questions about the faint glow of microwave radiation once hailed as proof that the universe was created by a "Big Bang."
Giant waves of air rippling through the atmosphere might spin up or intensify tornadoes when they interact with powerful thunderstorms.
A challenge in propulsion is increasing the lifetime of the thruster, which must run continuously for years during a mission. The plasmoid thruster potentially has a much longer lifetime because the plasma forms inductively, meaning that the plasma is not in contact with thruster components.
A new way of looking at a previously abandoned mathematical model might help astronomers study and accurately identify an exotic clan of gravitational waves.
Consistent research data shows that involvement in extracurricular activities helps in lowering the high school dropout rate, raises grades and gives students better odds of graduating from high school and attending college.
A new study comparing the output of 22 leading global climate models with actual climate data finds the models do an unsatisfactory job of mimicking climate change in key parts of the atmosphere. This research raises new concerns about the reliability of models used to forecast global warming.
The La Nina cooling of the tropical atmosphere continued in March, 2008, with temperatures in the tropics falling to their coldest seasonally-adjusted temperature (-0.49 C below the 20-year average for March) since the La Nina of March 1989.
