A New Model for Self-Organized Pattern Formation

by Ton Hoitink 1 July 202111 February 2022

Scale-dependent feedbacks in time, rather than in space, result in a new type of competition, explaining the regularly patterned landscape of Big Cypress National Preserve in South Florida.

Modeling Urban-Weather Effects Can Inform Aerial Vehicle Flights

by D. Wuebbles 9 June 202120 July 2022

Microscale modeling can be used to understand and predict urban weather with sufficient detail to inform and support flight safety for crewed and uncrewed aerial vehicles.

Raising Central American Orography Improves Climate Simulation

by Sarah Kang 9 June 20218 March 2022

Elevation of Central American orography significantly reduces the pervasive tropical rainfall bias by blocking the easterlies and consequently warming the northeastern tropical Pacific.

Species of Feces Help Phytoplankton Feed Itself

Katherine Kornei, Science Writer by Katherine Kornei 2 June 202118 January 2023

The unicellular plants more readily take up iron in the presence of salp feces than in krill feces, an experiment in Antarctica reveals.

Earthquake Rupture Solution is Up in the Air

by T. Parsons 28 May 202119 October 2021

Perhaps the most complex earthquake rupture ever studied is further constrained by signals from Earth’s ionosphere.

Scientists Hope Atmospheric Modeling Can Predict Meteotsunamis

Tim Hornyak, Science Writer by Tim Hornyak 24 May 202117 May 2022

The first extensively documented air pressure–driven meteotsunami on one of the Great Lakes presents an opportunity to use existing weather models to predict when these potentially deadly waves will strike.

How Do Croplands Reduce CO2 During the Growing Season?

by Susan Trumbore 20 May 202123 March 2023

Regional variations in the seasonal drawdown of atmospheric CO2 can be used as a benchmark for evaluating models and satellite-derived estimates of land carbon uptake.

The Space Weather Modeling Framework Goes Open Access

by T. Pulkkinen, T. I. Gombosi, A. J. Ridley, G. Toth and S. Zou 13 May 202118 July 2023

A versatile suite of computational models, already used to forecast magnetic storms and potential power grid and telecommunications disruptions, is preparing to welcome a larger group of users.

Saturn’s Dynamo Illuminates its Interior

by F. Nimmo 5 May 202115 March 2022

Saturn’s oddly symmetrical magnetic field can be explained by models in which the active dynamo region is overlain by a thick, stable layer cooled more strongly at the poles.
