An Interpretable Deep Learning Model for Detecting Tropical Cyclone Genesis Through Incorporation of the Dynamic and Thermodynamic Environment

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract In recent decades, tropical cyclone (TC) track forecasting has improved significantly. However, prediction of TC genesis (TCG) remains challenging. Accurate prediction of TCG is critical for disaster prevention and mitigation. This study develops an interpretable deep learning model that integrates 3D‐residual blocks with gated recurrent units

Advancing Heliophysics and Space Weather Modeling Through Open Science

Space Weather, Volume 24, Issue 6, June 2026.
Abstract We present a community‐wide effort to develop a strategy and action plan to advance heliophysics and space weather modeling through open science. While open science has the potential to enhance the quality and pace of scientific discovery, its application to scientific modeling requires more careful consideration regarding open data and open ...

Magnetotail Source of Premidnight Upward Field‐Aligned Currents: Nature of the Substorm Current System

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract The substorm current wedge constitutes the backbone of the substorm current system. Its field‐aligned current components include an upward current in the premidnight sector and a downward current in the midnight‐morning sector, which connect the auroral ionosphere to the magnetotail.
