A model of the Atlantic Meridional Overturning Circulation (AMOC), pioneered by Henry Stommel over 60 years ago, can exhibit realistic cyclic behavior if the role of Arctic salinity is included.
Hurricane winds can lead to coast downwelling, which brings warmer surface water near the coast and can contribute to the intensification of the landfalling hurricane.
The Lut Desert in Iran is an exceptional natural laboratory to study how wind moves sediment across the landscape. A new study quantifies erosional and depositional sediment fluxes of the desert.
Cloud-to-ground lightning is found to be the most important controller of wildfire occurrence in the Artic tundra of Alaska from 2001 to 2019.
Humidity increases with warming. Theory and observations about how increased humidity translates into more extreme rainfall can be reconciled if attention is paid to data and methods.
Using a physical experiment, researchers show how off-fault deformation occurs along strike-slip faults with different types of motion.
A new study presents the first evidence of the existence of an intraseasonal westward-propagating moisture mode over the Western Hemisphere.
Scientists present the first direct observations on the rapid evolution of a bright red auroral arc into a thin white-mauve arc known as STEVE.
Amateur radio observations provide a new method for studying large-scale ionospheric disturbances and HF communication impacts, and are important applications in ionospheric space weather monitoring.
