Mixed Precision Augmented GMRES

Numerical Linear Algebra with Applications, Volume 33, Issue 4, August 2026.
ABSTRACT We aim to accelerate the restarted generalized minimal residual (GMRES) method for the solutions of linear systems by combining two types of techniques. On the one hand, mixed precision GMRES algorithms, which use lower precision in certain steps of the inner cycles, offer significant reductions in computational and memory costs.

Regulating Fine‐Scale Resolved Convection in High‐Resolution Models for Better Hurricane Track Prediction

Geophysical Research Letters, 2023
High‐resolution atmospheric models are powerful tools for hurricane track and intensity predictions. Although using high resolution contributes to better representation of hurricane structure and intensity, its value in the prediction of steering flow ...

Improved Simulations of the Quasi‐Biennial Oscillation in the Lower Stratosphere of an Earth System Model

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.
Abstract Numerical experimentation using an atmospheric configuration of the Goddard Earth Observing System (GEOS) Earth System Model is used to examine the vertical structure of the simulated Quasi‐Biennial Oscillation (QBO). Using an improved representation of the parameterized gravity wave spectrum, it is demonstrated that with sufficient vertical ...

Visualization by immunofluorescence of infected peritoneal monocytic leukocytes from asymptomatic FV3 infected adult frogs following bacterial stimulation.

, 2014
PLs were harvested from uninfected controls (A, E) or asymptomatic FV3 infected outbred animals 3 days after bacterial stimulation (B, C D). Cells were cytocentrifuged on microscope slides, fixed with formaldehyde, permeabilized with ethanol, then ...

Impact of Observation Errors on All‐Sky Satellite Microwave Data Assimilation. Part I: Interplay Between Observation Error and Variational Bias Correction (VarBC)

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.
Abstract Careful specification of observation errors is crucial for assimilating all‐sky satellite microwave radiances, although uncertainties in these errors remain substantial. Operational centers often inflate observation errors to optimize model performance.

Locations of Eastern box turtles (Terrapene carolina carolina) and ephemeral ponds used for amphibian breeding at Kickapoo State Park in Vermilion County, Illinois in 2014 and 2015 before, during, and after ranavirus (FV3) outbreaks.

, 2018
In 2014 a 0.03km spatio-temporal cluster of FV3 cases was identified from July 15th–July 23rd. In 2015 a 0.16km spatio-temporal cluster of FV3 cases was identified from July 8th–July 23th.

Representation of East Pacific Easterly Waves in Subseasonal‐To‐Seasonal Forecasts of the Unified Forecast System

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.
Abstract East Pacific easterly waves (EPEWs) are critical precursors to tropical cyclogenesis and regional rainfall yet are poorly captured in subseasonal‐to‐seasonal (S2S) forecast models. This study evaluates how EPEWs are simulated in NOAA's Unified Forecast System (UFS) Prototypes 5–8 during May‐October relative to ERA5 reanalysis, using wave ...

Improved Knockout Methodology Reveals That Frog Virus 3 Mutants Lacking either the 18K Immediate-Early Gene or the Truncated vIF-2 α Gene Are Defective for Replication and Growth In Vivo

, 2011
To better assess the roles of frog virus 3 (FV3; genus Ranavirus , family Iridoviridae ) genes in virulence and immune evasion, we have developed a reliable and efficient method to systematically knock out (

Evaluating the Biases in Indian Summer Monsoon Rainfall Simulation Using the Global Storm Resolving Models: An Assessment of the DYAMOND Models

Earth and Space Science, Volume 13, Issue 6, June 2026.
Abstract This study evaluated the performance of various global storm‐resolving models (GSRMs) in simulating the Indian Summer Monsoon (ISM), highlighting the limitations of current global kilometer‐scale models in accurately representing precipitation patterns over the Indian subcontinent.
