Lifting the Veil on Martian Dust Storms

by Anni Määttänen and C. Newman 23 June 20202 February 2022

A special collection in JGR Planets presents insights from a long-awaited global dust storm on Mars in 2018 that was closely scrutinized by five orbiting and two landed spacecraft.

Explaining Cold and Fresh Southern Polar Ocean Surface Waters

by P. Rizzoli 6 May 202017 August 2022

Global climate models do not reproduce observed trends of the Southern polar ocean surface, but an increase in wind-transported sea ice that melts and inhibits mixing may account for the disparity.

Arctic Coast Erosion Linked to Large-Scale Climate Variability

by J. Sprintall 10 April 202015 November 2021

Changes in rates of Arctic coastal erosion detected from multi-decadal measurements are attributed to the shorter duration in the winter sea ice coverage and large-scale changes in the wind patterns.

Polar Stratosphere Resolves North Atlantic Jet “Tug of War”

by Alessandra Giannini 25 September 201929 March 2022

Getting the polar stratosphere right is critical in the simulation of North Atlantic climate change, which is shaped by the interaction of Arctic Amplification and tropical upper tropospheric warming.

Antarctic Seasonal Sea Ice Melts Faster Than It Grows

by C. Eayrs, D. Holland, D. Francis, R. Kumar, T. Wagner and X. Li 9 September 20199 August 2022

Winds are thought to play a significant role in driving the asymmetric seasonal cycle of Antarctic sea ice growth and melt.
