The Combined Effects of Variable Viscosity and Thermal Conductivity of An Unsteady Casson Fluid Flow Along a Vertical Porous Channel With Convective Cooling Walls, Using the Bivariate Spectral Local Linearization Method

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This study examines the combined impact of different thermal conductivity and viscosity on unsteady non‐Newtonian Casson fluid flow of incompressible, electrical conductivity in a porous vertical channel with convective cooling walls, uniform magnetic field, and constant pressure gradient.

Free‐breathing 3D pulmonary ventilation mapping at 0.55 T using stack‐of‐spiral out‐in bSSFP

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose To develop a free‐breathing pulmonary imaging technique that provides three‐dimensional (3D) structural images and regional ventilation maps, and to evaluate its repeatability and accuracy compared with two‐dimensional phase‐resolved functional lung (PREFUL) and global tidal volume.

The role of thermal stratification on the co‐spectral properties of momentum transport above an Amazonian forest

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Using micrometeorological measurements in Brazil at the Amazon Tall Tower Observatory, the scalewise impact of thermal stratification on turbulent momentum fluxes is explored in the roughness sublayer and the atmospheric surface layer. A scalewise co‐spectral budget model developed here revealed that the turbulent momentum co‐spectrum Fwu(kx)$$ {F}_{wu}

How sensitive are Sahelian mesoscale convective systems to cold‐pool suppression?

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Cold pools are a ubiquitous feature of mesoscale convective systems (MCSs) with important upscale impacts on West African climate, but their role in the maintenance of tropical MCSs remains debated. Using a 40‐day model with explicit convection and no rainfall evaporation, we show that cold pools do not play a primary role in Sahel MCS development or ...

A vertical‐slice frontogenesis test case for compressible non‐hydrostatic dynamical cores of atmospheric models

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Our article presents a new vertical‐slice test case for benchmarking atmospheric dynamical cores. The test case is based on the Eady frontogenesis problem, producing sharp fronts that provide a challenge for numerical models. This was not previously possible in a 2D vertical‐slice configuration unless the model is incompressible, so our test case ...
