Finding the pulse of the polar vortex

If you can predict the path of the jet stream, the upper atmosphere's undulating river of wind, then you can predict weather – not just for a week or two, but for an entire season. A new Stanford study moves toward that ...

Gulf Stream eddies as a source of iron

ETH researchers have fortuitously discovered that Gulf Stream eddies are rich in iron, and these eddies transport this essential micronutrient to the iron-poor North Atlantic Gyre. Before this discovery, the typical assumption ...

Spraying efficiently: Breaking up is hard to do

Atomizing liquids is vital to fuel-air mixing. Using oscillating liquid streams, breakup and drop formation can be improved compared to common straight jets. But the many dynamic interactions make it difficult for scientists ...

When the river runs high

A massive world-wide study of dry riverbeds has found they're contributing more carbon emissions than previously thought, and this could help scientists better understand how to fight climate change.

Image: Jovian jet stream

See a jet stream speeding through Jupiter's atmosphere in this new view taken by NASA's Juno spacecraft. The jet stream, called Jet N2, was captured along the dynamic northern temperate belts of the gas giant planet. It is ...
