How Do Atmospheric Rivers Respond to Extratropical Variability?

by Sarah Kang 3 February 20233 February 2023

Atmospheric river variability over the last millennium is primarily driven by north-south displacements in zonal winds induced by the annular modes.

Baked Contacts Focus a Lens on Ancient Lava Flows

by Anthony Pivarunas, Margaret Avery, Joseph Biasi and Leif Karlstrom 1 February 20231 February 2023

Two studies, conducted 40 years apart, show how combining field observations and thermal modeling can reconstruct the history of massive lava flows and how they altered the surrounding landscape.

Global Models Underestimated Groundwater Recharge and Discharge

by Guiling Wang 24 January 202324 January 2023

A new estimate for global groundwater recharge by rainfall and snowmelt, which dictates the upper limit of sustainable groundwater use, doubles the previous estimates from global models.

Four graphs from the paper.

Playing Bricks with Neural Networks to Learn Sorption Processes

by Xavier Sanchez-Vila 19 January 202318 January 2023

Designated neural network modules are combined to mimic numerically-discretized diffusion-sorption equations, which allows learning “missing pieces” in system understanding and their uncertainties.

3 simulations presented in the paper.
