A Lagrangian advection scheme with shape matrix (LASM) for solving advection problems
solving advection problems Lagrangian advection scheme
2014/12/19
A new Lagrangian advection scheme with shape matrix (LASM) is proposed to take advantage of the extreme low numerical diffusion of the Lagrangian methods. The tracer is discretized into finite parcels...
An orthogonal terrain-following coordinate and its preliminary tests using 2-D idealized advection experiments
orthogonal terrain-following coordinate preliminary tests 2-D idealized advection experiments
2014/12/19
We have designed an orthogonal curvilinear terrain-following coordinate (the orthogonal σ coordinate, or the OS coordinate) to reduce the advection errors in the classic σ coordinate. First, we rotate...
Advection of NH3 over a pasture field and its effect on gradient flux measurements
Advection NH3 pasture field gradient flux measurements
2009/7/30
Deposition of atmospheric ammonia (NH3) to semi-natural ecosystems leads to serious adverse effects, such as acidification and eutrophication. A step in quantifying such effects is the measurement of ...
Dependence of CO2 advection patterns on wind direction on a gentle forested slope
Dependence CO2 advection patterns wind direction gentle forested slope
2008/5/6
Gravitational flows generated on a gentle slope in stable conditions were analysed at a forested site at Vielsalm in Belgium. There were two distinct situations at the site, one corresponding to verti...
