An absence of precipitation combined with drying of the ground through evaporation can deplete fresh water crucial for societies and ecosystems. However, new research highlights a more remote driver of drought.

Changes in anvil clouds with warming do not produce a negative feedback on climate sensitivity as previously thought, according to an ensemble of cloud-resolving models.

The size and shape of the North American ice sheet during the Last Glacial Maximum was set by atmospheric moisture transport feedbacks during summer, not by the geometry of the earlier intermediate-sized ice sheet, according to a coupled climate–ice sheet model.

Hydrological sensitivity describes how much precipitation changes for a given warming. Here, the authors show that the hydrological sensitivity differs between the three tropical ocean basins, which influences land rainfall changes across the tropical and mid-latitude regions.

The Madden–Julian Oscillation (MJO), a large storm system over the Indian Ocean and Western Pacific, plays a crucial role in our ability to forecast Earth’s weather 2–4 weeks in advance. Now, research suggests that the predictability of the MJO itself is increasing and will continue to increase with global warming.

Three decades of meteorological observations show that Himalayan glaciers have been cooling because of intensified downslope winds, in contrast to the warming observed elsewhere in the region.

JWST observations of Jupiter reveal a narrow and intense atmospheric jet at the equator of the planet, close to its tropopause. The jet is manifest in the fast motions of equatorial hazes and is most likely a deep counterpart of the equatorial oscillations observed in Jupiter’s stratosphere.
