2014/12/11
A wide variety of different plankton system models have been coupled with ocean circulation models, with the aim of understanding and predicting aspects of environmental change. However, an ability to...
Numerical uncertainty at mesoscale in a Lagrangian model in complex terrain
Conservation of mass Lagrangian model euler model complex terrain Lagrangian particle dispersion models
2014/12/10
Recently, it has been shown that mass conservation in Lagrangian models is improved by using time-average winds out of Eulerian models. In this study, we evaluate the mass conservation and trajectory ...

A probabilistic approach to flood prediction over the Reno river basin, a medium-sized catchment in Northern Italy, has been tested using two different meteorological ensemble systems. The future prec...
Assessing uncertainty in radar measurements on simplified meteorological scenarios
Assessing uncertainty simplified meteorological scenarios
2010/1/27
A three-dimensional radar simulator model (RSM) developed by Haase (1998) is coupled with the nonhydrostatic mesoscale weather forecast model Lokal-Modell (LM). The radar simulator is able to model re...
Dealing with uncertainty:turbulent parameterizations and grid-spacing effects in numerical modelling of deep moist convective processes
turbulent parameterizations grid-spacing effects deep moist convective processes
2009/12/10
Computer power has grown to the point that very-fine-mesh mesoscale modelling is now possible. Going down through scales is clumsily supposed to reduce uncertainty and to improve the predictive abilit...
