Meiyu: The Dragon Dictating Rainfall Variability in East Asia

by Z. Li 13 July 202013 March 2023

According to Chinese myth, rain is water poured out of a dragon; in reality is the Meiyu that dictates rainfall in eastern Asia, producing rain belts jumping from south in spring to north in summer.

The Overlooked Role of Sulfur Dioxide Emissions from Volcanoes

by Lynn Russell 10 March 202022 April 2022

Volcanoes can warm as much as they cool. Prior simulations have neglected the important warming effects of sulfur dioxide emissions, making some results colder than they should be.

Novel Simulations of Upper Atmosphere Gravity Wave Dynamics

by William J. Randel 25 February 202019 October 2021

Gravity waves play a key role in driving upper atmosphere circulations but are poorly understood. New high-resolution simulations are resolving complex wave behaviors with unprecedented detail.
