A Model Intercomparison Study of Mixed‐Phase Clouds in a Laboratory Chamber
Abstract Supercooled liquid water often persists in mixed‐phase clouds for hours to days, even though a simple, well‐mixed Wegener‐Bergeron‐Findeisen model predicts rapid depletion of liquid water in the presence of ice. The persistence is well documented, but the relative importance of the maintaining mechanisms remains uncertain.

NORi: An ML‐Augmented Ocean Boundary Layer Parameterization
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.

Irreversible Stirring and Mixing of Tracers by Oceanic Internal Gravity Waves
Abstract Oceanic internal waves are often thought to be ineffective in stirring and mixing tracer fields such as heat, salt, carbon, and other nutrients. Due to their oscillatory nature, waves are expected to merely displace tracers periodically around their mean position.

Interval Data Assimilation: A Data Assimilation Scheme Where All Observations Are Intervals
Abstract With the proliferation of non‐conventional observations from low‐cost sensors, citizen science networks, and binary detection systems, data assimilation increasingly confronts observations that take the form of inequalities or intervals rather than precise point values.

ABSTRACT This study proposes a quantum computing algorithm for dynamic structural analysis, assuming the use of quantum computers. Specifically, we apply a quantum algorithm known as Hamiltonian Simulation (HS), which calculates the time evolution of the Schrödinger equation with time‐independent coefficients, to the equations of motion governing the ...

Solving Differential Equations in R: Package deSolve [PDF]
In this paper we present the R package deSolve to solve initial value problems (IVP) written as ordinary differential equations (ODE), differential algebraic equations (DAE) of index 0 or 1 and partial differential equations (PDE), the latter solved ...

Abstract Atmospheric wind‐pressure covariances (e.g., vertical wind‐pressure covariance, w′p′‾ $\overline{{w}^{\mathit{\prime }}{p}^{\mathit{\prime }}}$) affect boundary‐layer energetics and pressure‐related corrections, yet their sign and vertical structure are inconsistently reported.
