New Study Identifies Atmospheric Rivers as Contributor to Increased Snow Mass in West Antarctica

Scripps News (March 2nd 2021)

A new study from lead author Susheel Adusumilli has identified atmospheric rivers, the phenomenon of high-altitude concentrations of water in the atmosphere, as a main source of snowfall on the West Antarctic ice sheet. The project makes use of data from the ICESat-2 satellite which provides measurements of snowpack by observing precise changes in elevation along the surface of the ice sheet.

Simulation vs Reality: Researchers Modify Climate Model to Explain Expanding Antarctic Sea Ice

Scripps News (February 18th 2021)

Comparing climate models with sea ice observations exposes an interesting dilemma: despite model predictions that Antarctic sea ice should be shrinking, it has steadily expanded from 1979 to 2015. Scripps oceanographer Ian Eisenman has collaborated with California Institute of Technology researcher Shantong Sun to address this problem, identifying disparities between sea ice drift between models and real life.
