The goal of this project is to develop a fully coupled mesoscale atmosphere-ocean prediction system that can be used over any given area of the world. This goal is to be accomplished by coupling a fullphysics mesoscale ocean model to a mesoscale atmospheric forecast model; developing, testing, and evaluating software for the necessary supporting infrastructure; and by leveraging related program...

Although it is well established that the large-scale wind drives much of the world's ocean circulation, the contribution of the wind energy input at mesoscales (10-200 km) remains poorly known. Here we use regional simulations with a coupled high-resolution atmosphere-ocean model of the South Atlantic, to show that mesoscale ocean features and, in particular, eddies can be energized by their th...

As acoustic propagation, forest fire (Pimont et al., 2006), tree stability (Dupont and Brunet, 2008b) or pollen dispersion (Chamecki et al., 2009), a lot of applications needs an accurate representation of the boundary layer to observe its influence on these phenomena. Then, in order to better represent the dynamics into the surface layer, Large-Eddy Simulations (LES) are carried on using thinn...

In this paper, polymer solar cells with a tandem structure were investigated and optimized using a multiscale simulation scheme. In the proposed multiscale simulation, multiple aspects - optical calculation, mesoscale simulation, device scale simulation and optimal power conversion efficiency searching modules - were studied together to give an optimal result. Through the simulation work, depen...

Hazardous scenarios involving explosives are difficult to experimentally study and simulation is often the only viable approach to study highly reactive phenomena. Explosive simulations are computationally expensive, requiring supercomputing resources for continued scientific discovery in the field. Here an idealized mesoscale simulation of explosive grains under mechanical insult by a high-spe...

This paper presents an accurate and efficient computational strategy for the simulation of coupled masonry structures which combines a partitioned mesoscale modelling approach for brick-masonry components with a mortar mesh tying method for non-conforming interfaces. This allows the independent modelling of the individual structural components and the efficient tying of the subdomains with accu...

The non-hydrostatic mesoscale model MM5V3 is used to simulate the wind and temperature fields of the atmospheric boundary layer over Beijing area in summer with the mesh resolution of 1 km. The simulation results show that the numerical model can successfully simulate the urban heat island effect and the wind and temperature fields which are affected by the complicated topography and urban heat...

NOVEMBER 2003 AMERICAN METEOROLOGICAL SOCIETY | L ogistical and scientific operations in Antarctica are critically dependent on numerical weather guidance. The extreme, unforgiving environment amplifies the risks stemming from poor forecasts, while the sparse observing network often leaves forecasters heavily reliant on numerical weather prediction (NWP). To the operation of real-time mesoscale...

Electrical tomography can be used as a structural health monitoring technique to identify different damage mechanisms in composite laminates. Previous work has established the link between transverse cracking density and mesoscale conductivity of the ply. Through the mesoscale relationship, the conductivity obtained from electrical tomography can be used as a measure of the transverse cracking ...

Despite increasing evidence that marine predators associate with mesoscale eddies, how these marine features influence foraging movements is still unclear. This study investigates the relationship of at-sea movements of king penguins to mesoscale eddies using oceanographic remote sensing and movement data from 43 individual trips over 4 years. Simultaneous satellite measurements provided inform...
