Modeling Beijing’s Water Crisis

Elizabeth Thompson by Elizabeth Thompson 25 October 20176 February 2023

Beijing’s growing population is rapidly draining its water supplies. A new study examines how land use change affects groundwater storage beneath the megacity.

Can Large Electric Fields Power Jupiter’s X-ray Auroras?

by E. Underwood 19 October 201713 January 2023

Electric fields with megavolt potentials in Jupiter’s polar region accelerate particles to 100 times more energy than Earth’s typical auroral particles, a new study finds.

Imaging the Underlying Mechanics of New Zealand Earthquakes

by S. Witman 18 October 201711 January 2022

Researchers create a first-of-its-kind image to map electrical properties of rocks and minerals throughout the Hikurangi subduction zone.

Angles of Plasma Ropes near Mars Point to Different Origins

Sarah Stanley, Science Writer by Sarah Stanley 11 October 20174 May 2022

Variation in the orientation of flux rope features in Mars’s magnetotail suggests that some of them form on the planet’s Sun-facing side and travel to the night side.

Researchers examine how winds influence summer monsoon rainfall patterns in East Asia.

Summer Rainfall Patterns in East Asia Shift with the Wind

Sarah Stanley, Science Writer by Sarah Stanley 10 October 2017

Decades of data reveal the link between westerly winds and year-to-year changes in monsoon rainfall.

Ocean Dynamics May Drive North Atlantic Temperature Anomalies

Sarah Stanley, Science Writer by Sarah Stanley 9 October 20173 February 2023

A new analysis of sea surface temperature and salinity over several decades seeks to settle the debate on which of two mechanisms underlies the Atlantic Multidecadal Oscillation.

Researchers examine how the impact of atmospheric streams of water vapor varies across California

California Floods Linked to Atmospheric Water Vapor “Rivers”

Sarah Stanley, Science Writer by Sarah Stanley 26 September 201730 January 2024

Narrow atmospheric streams of water vapor that deliver heavy rains are more commonly associated with floods and debris flows in northern California than with flash floods in southern California.

New mathematical modeling suggests lightning strikes may leave traces similar to those of meteorites

Lightning Strikes May Leave Traces Like Those of Meteorites

Sarah Stanley, Science Writer by Sarah Stanley 20 September 20174 October 2021

Scientists have long interpreted shocked quartz as definitive evidence of a past meteorite impact, but the shock wave caused by lightning striking granite also produces this distinctive feature.

Juno Gets Spectacular View of Jupiter’s Aurora

by Mark Zastrow 7 September 20178 August 2022

The NASA spacecraft has taken images of Jupiter’s powerful aurora dancing around its poles, revealing never-before-seen details in their structure.

Increased winter flows in the Tanana River have puzzled researchers—until now

Why Are Arctic Rivers Rising in Winter?

by E. Underwood 5 September 20173 March 2023

Increased glacial melt is boosting winter streamflows by filling aquifers, a new study on an Alaskan river suggests.
