Imputing Missing Long‐Term Spatiotemporal Multivariate Atmospheric Data With CNN‐Transformer Machine Learning

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract Continuous physical domains are important for scientific investigations of dynamical processes in the atmosphere. However, missing data—arising from operational constraints and adverse environmental conditions—pose significant challenges to accurate analysis and modeling.

Adaptive expectations and reaction to information

open access: yesEconomica, Volume 93, Issue 370, Page 488-523, April 2026.
Abstract This paper develops a model combining adaptive expectations with noisy signals, and derives three coefficients and one impulse response function (IRF): the Coibion–Gorodnichenko (CG) coefficient capturing consensus under‐reaction to information, the Bordalo–Gennaioli–Ma–Shleifer coefficient capturing individual over‐reaction, the Kohlhas ...

Financial Time Series Uncertainty: A Review of Probabilistic AI Applications

open access: yesJournal of Economic Surveys, Volume 40, Issue 2, Page 915-953, April 2026.
ABSTRACT Probabilistic machine learning models offer a distinct advantage over traditional deterministic approaches by quantifying both epistemic uncertainty (stemming from limited data or model knowledge) and aleatoric uncertainty (due to inherent randomness in the data), along with full distributional forecasts.

Characteristics of Intense Multi‐Day Wet Spells Over West Africa

open access: yesInternational Journal of Climatology, Volume 46, Issue 4, 30 March 2026.
The study reveals a significant increase in intense wet spells, particularly in KASS‐D, emphasising the value of dense rain‐gauge networks. Larger‐sized events have grown, while smaller ones declined, boosting 3‐day and 5‐day wet spells' contribution to annual rainfall, with the Guinea Coast showing the highest increase and the Sahel the lowest ...

Data‐Driven Exploration of Tropical Cyclone's Controllability

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Although the chaotic nature of the atmosphere may enable efficient control of tropical cyclones (TCs) via small‐scale perturbations, few studies have proposed data‐driven optimization methods to identify such perturbations. Here, we apply the recently proposed Ensemble Kalman Control (EnKC) to a TC simulation.
