Landfall Temperature of Atmospheric Rivers on the US West Coast

by Minghua Zhang 3 March 202323 February 2023

Atmospheric rivers that start in warm areas of the North Pacific generally stay warm, leading to warmer landfall temperatures in the western United States.

Rate of Temperature–Precipitation Scaling in Rainfall Events

by Minghua Zhang 1 March 202322 February 2023

Future extreme rain will be embedded in shorter, more convective dominant rainfall events in the northeastern region of North America, leading to larger rate in future temperature-precipitation scaling.

A New Coupled Modeling System Improves Forecast Skills

by Minghua Zhang 27 February 202322 February 2023

Building on older versions, the new Global Ensemble Forecast System with coupled atmosphere-land-ocean-ice-wave models has better forecasting skills of the atmosphere than the uncoupled system.

Mesoscale Convective Systems Impact Synoptic Wave Forecast

by Minghua Zhang 23 February 20236 March 2023

Scientists provide a process-level understanding of how mesoscale convective systems modify the evolution of the large-scale Rossby wave packet downstream and the jet stream.

Scientists Can Now Map Lightning in 3D

by Morgan Rehnberg 15 February 202315 February 2023

A new approach enables meter-scale localization of lightning strikes. And it’s already illuminating the basic physics of the phenomenon.

When the Aral Sea Dried Up, Central Asia Became Dustier

by Saima May Sidik 30 November 202219 December 2022

Winds kick up large amounts of dust from the desert that has formed as the world’s fourth largest lake has disappeared, spreading it around the region and raising concerns about public health.

What is the Best Predictor of Landfalling Hurricane Damage?

by Jonathan Zawislak 21 October 202218 October 2022

A new study finds that the minimum sea level pressure, as another measure of hurricane strength, is a better predictor of hurricane damage in the United States than the maximum sustained wind speed.

Modeling Stratosphere-Troposphere Coupling in a Changing Climate

by William J. Randel and Gang Chen 18 October 202214 October 2022

Climate models have disagreed on the future evolution of the stratospheric polar vortex and links to the troposphere, but a new study revisits this problem with state-of-the-art climate models.
