K computer runs largest ever ensemble simulation of global weather
Ensemble forecasting is a key part of weather forecasting today. Computers typically run multiple simulations, called ensembles, using slightly different initial conditions or assumptions, and then analyze them together to ...
Computer simulation shows the sun's "heartbeat" is magnetic
Takeoffs and landings cause more precipitation around major airports
Researchers have found that areas near commercial airports sometimes experience a small but measurable increase in rain and snow when aircraft take off and land under certain atmospheric conditions.
Global climate prediction system models tested
(Phys.org)—A new study has found that climate-prediction models are good at predicting long-term climate patterns on a global scale but lose their edge when applied to time frames shorter than three decades ...
Reality catches up with sci-fi in storm drones
At the time it premiered, the film "Twister" put forth a fantastical science fiction idea: Release probes into a storm in order to figure out which tornadoes could develop into killers. It's no longer fiction. ...
A glimpse at the future? A smartphone in your glasses
(Phys.org)—No need to turn to your smartphone to check the time, look at your agenda or the weather forecast, read a text message or map a route in an unfamiliar city. All this information, and much more, will soon be displayed ...
Biggest solar storm in years races toward Earth (Update 2)
The largest solar storm in five years was due to arrive on Earth early Thursday, promising to shake the globe's magnetic field while expanding the Northern Lights.
90 million laser shots bring wind satellite back on track
(Phys.org) —Developing new ways of monitoring Earth is always demanding, but ESA's Aeolus mission has faced some particularly difficult technical challenges. However, with the success of intense high-energy ...
'La Nada' climate pattern lingers in the Pacific
(Phys.org) —New remote sensing data from NASA's Jason-2 satellite show near-normal sea-surface height conditions across the equatorial Pacific Ocean. This neutral, or "La Nada" event, has stubbornly persisted ...
Lake-effect snow sometimes needs mountains
University of Utah researchers ran computer simulations to show that the snow-producing "lake effect" isn't always enough to cause heavy snowfall, but that mountains or other surrounding topography sometimes ...
Forecast for Titan: Wild weather could be ahead
(Phys.org) —Saturn's moon Titan might be in for some wild weather as it heads into its spring and summer, if two new models are correct. Scientists think that as the seasons change in Titan's northern hemisphere, ...
Weather forecasts on Mars
(Phys.org) —In the north of the red planet snowfalls occur with great regularity. Expeditions of Mars rovers into this region could therefore be easily planned.
Orbital Sciences ready for first launch of Antares rocket
Orbital Sciences, one of two private US firms chosen by NASA to shuttle cargo to the International Space Station, is preparing for the first launch of its Antares rocket Wednesday.
Google gives glimpse of Internet glasses
Google on Wednesday gave the world a glimpse of its vision for letting people look at life through Internet-tinted glasses.
