Origin of Dawnside Subauroral Plasma Flows in Geomagnetic Storms

by Susan Trumbore 12 September 202218 October 2022

Geomagnetic storms induce fast plasma flows next to the aurora and affect space weather. Lin et al. explain the origin of a special “dawnside” plasma stream that occurs only during extreme storm events.

Why Does It Rain So Much Over Tropical Land?

by Nicolas Gruber 12 September 202220 December 2022

Analyses of observations show that tropical land receives more rain than its fair share, owing to a proposed negative feedback that is not captured in current climate models.

The Long-Lasting Impact of a Nuclear War on the Ocean

by Nicolas Gruber 12 September 202227 September 2022

Model simulations of the impact of a large-scale nuclear war reveal long lasting effects with much of the ocean not returning to pre-war levels despite the cessation of the initial cooling.

Oceans Warming Increases Xinjiang’s Precipitation, but Scarcity Stays

by Tissa Illangasekare 8 September 2022

A transition toward an unusually wet condition due to ocean surface warming-induced increased precipitation will not alleviate the water scarcity risk in Xinjiang, China.

New Tool to Decipher Past Upper Troposphere Temperatures

by Susan Trumbore 9 August 202230 August 2022

Small variations in clumped O2 isotopes reflect temperatures in the upper troposphere. Bubbles measured in polar ice cores show the global lapse-rate appears to steepen during the Last Glacial Maximum.

Ceres: Missing Craters, Crust Thickness Variation by Interior Convection

by Bethany Ehlmann 18 July 202231 January 2023

Models show that several puzzling features about Ceres’ topography, gravity anomalies, and crater size distribution may be explained by asymmetric hemispherical convection due to radiogenic heating.

Zircons and Plate Tectonics

by Vincent Salters 29 April 20223 May 2022

New data on ancient zircons points to a transition from stagnant lid to subduction style tectonics at 3.6 Ga ago.

Less Air Travel May Partially Contribute to Global Warming

by Tong Zhu 14 April 202219 September 2022

Decrease in aircraft soot emission, as shown by COVID-19 lockdown, leads to a significant increase in ice crystal number in cirrus clouds, and results in a small global positive radiative effect.

Ice Begets Ice in the Clouds of the Southern Ocean

by Bjorn Stevens 17 March 202217 August 2022

Poorly understood ice multiplication processes, not aerosols, may determine the microphysical properties of climatologically important clouds over the Southern Ocean.
