Diurnal Variation of Rainfall over the Equator Revisited
Radar data show an afternoon precipitation maximum in the equatorial Indian Ocean in addition to the nocturnal maximum; this occurs under light surface winds and suppressed large-scale convection.
New Lidar Comparisons of Temperatures Near the Mesopause
For the first time, simultaneous measurements of upper atmosphere temperatures over altitudes 80 to 110 kilometers have been made by two complementary lidar techniques.
How Do We Accomplish System Science in Space?
Exploring Systems-Science Techniques for the Earth’s Magnetosphere-Ionosphere-Thermosphere; Los Alamos, New Mexico, 24–26 July 2018
Observing Winter Mixing and Spring Bloom in the Mediterranean
A new special issue of JGR: Oceans and JGR: Atmospheres presents new insights into the dynamics of dense water formation in the western Mediterranean Sea and its biogeochemical consequences.
New Characterization of the Mesospheric Polar Vortices
Polar vortices play a central role in coupling the atmosphere from the ground to the middle atmosphere. New satellite diagnostics describe mesospheric polar vortices and coupling to lower altitudes.
UCAR to Keep Managing National Center for Atmospheric Research
The head of the University Corporation for Atmospheric Research says he is excited about “taking our science to the next level.”
High-Altitude “Wind Walls” Discovered near Magnetic Poles
Satellite imaging reveals two narrow channels of extreme winds surrounded by gentle opposing flow 140–250 kilometers above sea level.
Drones Swoop in to Measure Gas Belched from Volcanoes
A team of volcanologists, chemists, physicists, and engineers from around the world test novel techniques at Central America’s two largest degassing volcanoes.
Exploring the Interplay Between Ocean Eddies and the Atmosphere
Ocean Mesoscale Eddy Interactions with the Atmosphere: A CLIVAR Workshop; Portland, Oregon, 17–18 February 2018
