New satellite observations of polar stratospheric clouds have advanced our understanding of how, when, and where they form, their composition, and their role in ozone depletion.
Researchers uncover how black carbon evolves from hydrophobic particles to cloud nucleation sites, eventually removing the heat-absorbing particles from the sky.
The two hemispheres feature the same planetary albedo despite a larger land fraction in the north, because storms over the southern ocean are cloudier than their northern counterparts.
Clouds make climate modeling on Earth difficult. Identifying—and even defining—atmospheric phenomena on other planets is the next big exoplanet challenge.
A new mission involving synchronized aircraft observations is collecting data vital for improving our understanding of how aerosol particles and clouds influence each other.
Satellites in the sky combined with computers on the ground detect and track volcanic ash clouds, like those produced by Soufrière St. Vincent in April, in near-real time.
A shift in the tropopause jet may have triggered the unusual number of high-altitude clouds that briefly appeared in the early summer of 2019.
Night-shining clouds can be diagnostic tools to better understand how human activity is changing the meteorology of the mesosphere.
Turbulence causes local variations in relative humidity, which can push particles past a critical saturation threshold for droplet nucleation.
Wildfires create airborne plumes of organic and inorganic matter as they burn. These particles can nucleate cloud-forming ice crystals and affect cloud dynamics, precipitation, and climate.
