Mesoscale Modeling of Titan’s Shangri‐La Region: The Impact of Surface Properties on Winds
Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.Abstract The knowledge of Titan’s near‐surface atmosphere is sparse. The Huygens descent probe measured winds, and the multiple dune field observations and possible dust storms suggest active near‐surface dynamics. The Dragonfly rotorcraft lander will fly close to the surface in the Shangri‐La region, near the Huygens landing site, where complex dune ...

Water Resources Research, Volume 62, Issue 10, October 2026.Abstract Bedload transport widely occurs in natural environments and encompasses flow regimes from saltation to sheet‐flow, with markedly different fluid‐particle interaction characteristics. Understanding these mechanisms requires a numerical tool capable of capturing both the turbulence and fluid‐particle interactions, for which challenges exist due ...

Submesoscale Frontogenesis Drives Strong Finescale Tracer Subduction
Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.Abstract Vertical exchange between the surface mixed layer (ML) and the interior is important for biogeochemistry and air–sea interaction. Focused observations have consistently shown that submesoscale processes (horizontal scales of 0.1–10 km) generate substantial exchange of heat, freshwater, and biogeochemical tracers across the ML base ...

Bénard–Marangoni convection at low Prandtl number
, 1999 Surface-tension-driven Bénard convection in low-Prandtl-number fluids is studied by means of direct numerical simulation. The flow is computed in a three-dimensional rectangular domain with periodic boundary conditions in both horizontal directions ...

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.Abstract Machine learning offers a flexible route to constitutive modeling, with two emergent questions for geoscience applications: what level of thermodynamic constraint should be embedded in the network architecture, and how should predictive uncertainty be quantified when extrapolating from laboratory to field conditions? We address both challenges

Existence and Uniquence of the Global Solutions to Prandtl Equation and Properties of the Solutions to Some Degenerate Parabolic Equation [PDF]
, 2007 本文分为三部分,第一部分是研究Prandtl方程组整体解的存在惟一性.Prandtl方程组来自于流体力学中边界层理论,已有许多理论、数值计算和试验方面的结果.由于对于小粘性流体Prandtl方程组是Navier-Stokes方程的近似已被理实验所证实,而Prandtl方程组解的计算明显比Navier-Stokes方程来得容易,因此Prandtl方程已经成为边界层理论发展的基础和研究流体力学的重要组成部分.Prandtl方程的数学理论研究对于揭示小粘性流体的运动本质具有重要的意义 ...
