Sensitivity of flower trade‐wind cloud organisation to mesoscale atmospheric heterogeneities

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Trade‐wind cloud organisation is insensitive to dynamical and thermal heterogeneities but very sensitive to humidity mesoscale heterogeneities, especially in the cloud layer, where they form moist patches, and not in the sub‐cloud layer. Clouds and rain develop in moist patches, then cold pools develop progressively, initiating mesoscale circulations ...

Snow water equivalent retrieved from X- and dual Ku-band scatterometer measurements at Sodankylä using the Markov Chain Monte Carlo method [PDF]

The Cryosphere
Radar at high frequency is a promising technique for fine-resolution snow water equivalent (SWE) mapping. In this paper, we extend the Bayesian-based Algorithm for SWE Estimation (BASE) from passive to active microwave (AM) application and test it using ...

Study of a temperature gradient metamorphism of snow from 3-D images: time evolution of microstructures, physical properties and their associated anisotropy [PDF]

The Cryosphere, 2014
We carried out a study to monitor the time evolution of microstructural and physical properties of snow during temperature gradient metamorphism: a snow slab was subjected to a constant temperature gradient in the vertical direction for 3 weeks in a cold

Measurement of Microstructure of Snow from Surface Sections

Defence Science Journal, 1995
A new approach to modelling the microstructure of snow is presented. The features involved in this formulation include skeletonising of the granular material and the modelling of the necks as a system of truncated cones. The skeletonising involves the process of representing the granular structure by a series of lines describing the grains and the

A microstructural approach to model heat transfer in snow [PDF]

Geophysical Research Letters, 2005
The relation between heat flow through snow and microstructure is crucial for the comprehension and modeling of thermophysical, chemical, and mechanical properties of snow. This relationship was investigated using heat flux measurements combined with a microstructural numerical approach.

Fluorescently Labeled Gradient Hydrogels Reveal Matrix‐Dependent Cell Responses to Substrate Stiffness

Small, EarlyView.
This work demonstrates a new thermophoretic strategy to fabricate fluorescently labeled stiffness gradient hydrogels, enabling contactless stiffness characterization. Fibroblasts cultured on gradient GelMA and Gellan gum hydrogels revealed distinct cell morphology and migration behavior.

Stochastic equation of fragmentation and branching processes related to avalanches [PDF]

, 2015
We give a stochastic model for the fragmentation phase of a snow avalanche. We construct a fragmentation-branching process related to the avalanches, on the set of all fragmentation sizes introduced by J. Bertoin.

Dependence of thermal conductivity of snow on microstructure

Journal of Earth System Science, 2008
A geometrical model, including different geometrical shapes influencing thermal conductivity of snow is proposed. The geometrical model has been assumed to comprise of unit cells having solid (ice) inclusion as an aggregation of spherical, cylindrical or cubical shapes with vertical connection, arranged in a cubic packing.

The Material Basis of 18th‐Century Meissen Porcelain

Archaeometry, EarlyView.
ABSTRACT In the summer of 1708, the quest for making hard‐paste porcelain from Saxonian clay and other mineral resources succeeded. This was achieved by applying as its essential ingredient newly discovered pure kaolin from Heidelsberg near Aue, western Saxon Ore Mountains.
