Wind Speed Governs Turbulence in Atmospheric Inversions

by Terri Cook 21 September 201811 August 2022

Measurements made during a field campaign in Idaho indicate that the speed of winds 2 meters above Earth’s surface determines the type of turbulence present in nighttime inversions.

Tides and Waves Interact to Cause Hurricanes in Near-Space

by A. Rodger 23 May 201811 May 2022

The interaction of tides and waves generated in the lower atmosphere can cause the mean zonal wind speed in the lower ionosphere to oscillate equivalent to a category 1 hurricane at Earth’s surface.

Ocean Wind Satellites Observe an Amazonian Drought

by Ankur R. Desai 9 February 20186 March 2023

Satellites designed to observe ocean winds can also be used to map both forest structure and water content, allowing researchers to disentangle factors of carbon loss due to drought in the Amazon.

Researchers examine how the spread of a major atmospheric circulation system will dry portions of the globe.

Pinpointing Effects of Hadley Cell Expansion

by S. Witman 6 February 20181 March 2023

As a major atmospheric circulation system spreads farther poleward, some regions are drying out. But as time passes, will this drying be symmetrical across the globe?

Researchers use sounding rockets to measure how Earth’s auroras affect winds in the upper atmosphere.
