Le logiciel de calcul distribué Snowflakes
… mémoire présente le logiciel de calcul distribué Snowflakes, un outil conçu pour télécharger et exécuter des applications arbitraires de façon automatique. Snowflakes possède un économiseur d'écran qui peut être installé sur les ordinateurs d'un laboratoire informatique afin de récupérer la …

Evaluations of microphysical parameterizations in retrieval algorithms for snowfall particle size distributions from dual frequency radar measurements
… for dual frequency retrievals assume that snowflakes have a constant density, scatter as homogeneous particles, and have an exponential size distribution. These assumptions disagree with the results of observations and simulations of snowflakes, but the impact that more realistic …

Snowfall Characterization by Field Observation and Atmospheric Sounding
… interlocking shapes as an aggregate snowflake. Snowflakes are collected on a black cloth, next to a scale, and photographed using a macro magnification. Snowflakes captured at the surface are characterized by their appearance from the habit, shape, size, symmetry, thickness, concentration, and …

Modeling heterogeneity in the microbial world
… living cells are identical. Like tiny, squishy snowflakes, even seemingly identical cells (belonging to isogenic populations, and living under macroscopically similar conditions), will experience variations in their local microenvironments and in the numbers of gene copies, messenger RNAs, …

Assessing fall velocity-maximum dimension relationships and particle size distributions for snowfall
… dimension and the particle size distributions of snowflakes from many snowfall events were analyzed. Observed relationships between fall velocity and maximum dimension were compared with previously derived relationships, and it was found that, in most cases, no single curve represented the …

Development of a discrete numerical approach to the Fredholm Integral Method for evaluating microwave scattering by irregular hydrometeors
… hydrometeors in the melting layer where snowflakes aggregate. These contain air, ice and liquid water and therefore complex to model. In this study, the particles were modelled discretizing their volume, filling it with cubic or spherical cells according to their weighted contents. The …

Snow and window: archetypes of imagination
… is the central theme of the focused texts. Snowflakes falling on the window pane allegorically represent words on the page, and the observation of this process is a metaphor for the ongoing creative and receptive acts. Meditative contemplation of nature and of the processes of writing and …

Instabilities and flow-induced structures in anisotropic systems
… Examples range from microscopic dendritic snowflakes to macroscopic sand ripples and intricate river networks. Central to the formation of patterns is the concept of an instability; complex forms spontaneously develop when a system is driven out of equilibrium. Nature leverages …

Snowfall Interception and Ablation in Needleleaf Canopies: Observations and Model Development
… given the lower terminal fall velocity of snowflakes compared to raindrops. An evaluation of existing theories representing ablation of snow intercepted in needleleaf canopies was conducted using observations collected by a weighed hanging tree, weighed subcanopy snow buckets, tipping …
