The All-In-One Cyclone Identification Framework
Researchers present a new framework for global detection and classification of all low-pressure systems.
Rapid Thunderstorm Charging Produces Strong Gamma‐Ray Glows
A new study explains how thunderstorm electric fields produce strong gamma‐ray glows with oscillating gamma‐ray rates, and that these oscillations develop into intense pulse trains that closely resemble terrestrial gamma-ray flashes.
Impacts of Urban Heat and Friction on a Tropical Cyclone
A new computer modeling-based study demonstrates dual mechanisms that reduce pre- and post-landfall tropical cyclone intensity.
Lightning Initiating at High Altitudes May Develop Continuously
Recent radio observations reveal a new mode of initial lightning development in the form of continuous initial breakdown burst of several kilometers in length at high altitudes within thunderstorms.
Five Decades of Stratospheric Aerosols from Balloon Measurements
Long-term global measurements of stratospheric aerosols reveal climatological structures and processes controlling new particle formation.
Air-Ice-Ocean Coupling Observed in an Arctic Cyclone Event
New observations show detailed features of the ice-ocean response to a strong Arctic cyclone in the winter of 2019-2020.
Improving Climate Models: Black Carbon Mixing and Shape Effects
A new study introduces a parameterization scheme to capture the complex optical properties of atmospheric black carbon, accounting for its mixing state, nonsphericity, and heterogeneous coatings.
Atmospheric Effects of Hunga Tonga Eruption Lingered for Years
A new study builds on previous research of the underwater volcano’s effects on the climate.
Past and Future Changes in Atmospheric Clear-Air Turbulence
A new study evaluates long-term changes in atmospheric clear-air turbulence based on meteorological reanalysis and climate model simulations.
