On Destruction of a Thermally Stable Layer by Compositional Convection in the Earth's Outer Core

Frontiers in Earth Science, 2018
We discuss destruction of a thermally stable layer in the upper part of the Earth's outer core by compositional convection excited at the inner core boundary.

Innovative Strategies for Observations in the Arctic Atmospheric Boundary Layer (ISOBAR)—The Hailuoto 2017 Campaign

Atmosphere, 2018
The aim of the research project “Innovative Strategies for Observations in the Arctic Atmospheric Boundary Layer (ISOBAR)” is to substantially increase the understanding of the stable atmospheric boundary layer (SBL) through a combination of ...

Concerning the interaction of non-stationary cross-flow vortices in a three-dimensional boundary layer [PDF]

Recently there has been much work devoted to considering some of the many and varied interaction mechanisms which may be operative in three-dimensional boundary layer flows. This paper is concerned with resonant triads of crossflow vortices.

Modeling the Dynamics of the Atmospheric Boundary Layer Over the Antarctic Plateau With a General Circulation Model

Journal of Advances in Modeling Earth Systems, 2018
Observations evidence extremely stable boundary layers (SBL) over the Antarctic Plateau and sharp regime transitions between weakly and very stable conditions. Representing such features is a challenge for climate models. This study assesses the modeling

On the coupling between a supersonic boundary layer and a flexible surface [PDF]

The coupling between a two-dimensional, supersonic, laminar boundary layer and a flexible surface is studied using direct numerical computations of the Navier-Stokes equations coupled with the plate equation.

On the Relationship Between Aerosol and Boundary Layer Height in Summer in China Under Different Thermodynamic Conditions

Earth and Space Science, 2019
The observed relationships between boundary layer height (BLH) and PM2.5 on a national scale remain unclear due to the dearth of observations. Here we investigated this relationship from a unique perspective of thermodynamic stability in the planetary ...

Effects of Lubricant Composition on Adsorption Behavior of Proteins on Rubbing Surface and Stability of Protein Boundary Film

Tribology Online, 2008
Polyvinyl alcohol (PVA) hydrogel is one of the candidate materials for artificial cartilage. In previous research, it was found that the structure of protein boundary film is important essence for wear reduction of PVA hydrogel, and the stability of ...
