Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Drizzle initiation through the collision and coalescence of cloud droplets plays a crucial role in warm cloud precipitation. Recent theoretical studies suggest that the influence of collisional growth on the droplet size distribution can be quantified by a non‐dimensional drizzle number (Dz).

Temperature statistics in turbulent Rayleigh-Bénard convection
, 2011 . Rayleigh-Bénard convection in the turbulent regime is studied using statistical methods. Exact evolution equations for the probability density function of temperature and velocity are derived from first principles within the framework of the Lundgren ...

Vertical heat transport at infinite Prandtl number for micropolar fluid
Archives of Mechanics, 2020 We investigate the upper bound on the vertical heat transport in the fully 3D Rayleigh–Bénard convection problem at the infinite Prandtl number for a micropolar fluid.

Topographically Controlled Marangoni-Rayleigh-Bénard Convection in Liquid Metals
Fluids, 2021 Convection induced in a layer of liquid with a top free surface by a distribution of heating elements at the bottom can be seen as a variant of standard Marangoni–Rayleigh–Bénard Convection where in place of a flat boundary at constant temperature ...

Scaling of Latitude‐Dependent Heat Transport in Geostrophic Convection
Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract Latitudinal variations in heat transport shape the thermal and magnetic evolution of rapidly rotating planets, stars, and icy moons. Although global simulations have revealed strong equatorial–polar contrasts, a predictive scaling theory has been lacking.

A Model of Rayleigh-Bénard Convection
, 2013 This chapter presents a model of Rayleigh–Bénard convection. It first describes the fundamental dynamics expected in a fluid that is convectively stable and in one that is convectively unstable, focusing on thermal convection and internal gravity waves ...

Rayleigh-Bénard Convection for Nanofluids for More Realistic Boundary Conditions (Rigid-Free and Rigid-Rigid) Using Darcy Model [PDF]
International Journal of Mathematical, Engineering and Management Sciences, 2019 In this article, Rayleigh-Bénard convection for nanofluids for more realistic boundary conditions (rigid-free and rigid-rigid) under the influence of the magnetic field is investigated.

Fast and Slow Signal Propagation in Abiotic Polypeptide Assemblies
ChemBioChem, Volume 27, Issue 6, 27 March 2026.Proteinoid microspheres formed by thermal polymerization of amino acids exhibit spontaneous electrical potential fluctuations without genetic material, membranes, or ion channels. Multi‐electrode recordings and electron microscopy reveal composition‐dependent voltage oscillations, long‐term drifts, and correlated signals across electrodes.

Flow Compensation Recovers Sensitivity Lost to Convection in Gradient‐Enhanced TOCSY NMR Experiments
Chemistry–Methods, Volume 6, Issue 3, March 2026.Gradient‐enhanced TOCSY techniques are an essential tool in the NMR spectroscopist's toolkit. However, in the presence of convection, signal intensities can be severely diminished, an issue that is particularly common when using cryoprobes. Here, we present an easily implemented TOCSY experiment that reverses signal loss due to convection and ...
