Wind Stress is not the Ceiling of Momentum Flux to the Ocean

by Lei Zhou 15 February 202116 September 2022

The ocean is mainly driven by wind stress, but simultaneous observations show that the gain of momentum flux by the ocean can be larger than the wind stress due to the influence of ocean waves.

The Importance of Wind for the Fate of Volcanic Eruption Columns

by M. Pistolesi 13 November 20202 May 2022

A theoretical model coupled to lab experiments on turbulent jets with reversing buoyancy sheds new light on the role of wind in controlling the dynamics of volcanic eruptive columns.

Successfully Simulating Atmospheric Gravity Waves

by Morgan Rehnberg 30 September 202019 October 2021

These waves are key to moving energy from the troposphere to the thermosphere, but until now they haven’t been well described at high altitudes in computer models.

A New Perspective on a Classic Climate Conundrum

by Alessandra Giannini 6 August 202012 January 2022

The Lagrangian method applied to tracking water transport between the Atlantic and Pacific basins reveals a larger contribution by mid-latitude westerly winds across Eurasia than previously thought.

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.
