NORi: An ML‐Augmented Ocean Boundary Layer Parameterization

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 9, September 2026.
Abstract NORi is a machine learning (ML) parameterization of ocean boundary layer (BL) turbulence that is physics‐based and augmented with neural networks. NORi stands for neural ordinary differential equations Richardson number (Ri) closure. The physical parameterization is controlled by a Richardson number‐dependent diffusivity and viscosity.

Three‐Dimensional Simulation of Tile Drainage System for Farmland: Quantifying Tile Drainage Impacts on Hydrological Cycle

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract Tile drainage is widely adopted in the U.S. Midwest to manage excess soil water and sustain agricultural productivity, yet its impact on key water budget components—particularly evapotranspiration (ET)—remains insufficiently understood under varying drainage designs and climate conditions.

The Concept of the Mixing Index

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract Many current measures of mixing, such as the statistics of concentration, the scalar dissipation rate, or dilution index, are based on the dilution of a single component or pseudo‐component. Because of this, they miss the influence of numerous conditions that directly change true mixing, such as initial separation of chemically distinct water ...

The Impact of Double Subduction on Plate Velocity and Euler Pole Shifts: Insights From Spherical Subduction Models

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Same‐dip double subduction (SDDS), in which two parallel slabs dip in the same direction, has been linked to accelerated plate motion in both modern and ancient convergent systems, such as the Late Cretaceous Africa–Eurasia system. Yet a systematic framework for quantifying how SDDS alters plate kinematics in a large‐scale spherical geometry ...

Monetary and Macroprudential Policies under Dollar‐Denominated Foreign Debt

Journal of Money, Credit and Banking, Volume 58, Issue 6, Page 1693-1728, September 2026.
Abstract This paper studies monetary and macroprudential policies in a small open economy that borrows from abroad in foreign currency. The model features a novel mechanism in which exchange rate depreciation triggered by a borrowing constraint is amplified through balance of payments adjustments, increasing the real burden of foreign debt and causing ...
