Numerical simulation of helical-vortex effects in Rayleigh-Bénard convection
Numerical simulation helical-vortex effects Rayleigh-Bénard convection
2009/11/9
A numerical approach is substantiated for searching for the large-scale alpha-like instability in thermoconvective turbulence. The main idea of the search strategy is the application of a forcing func...
Simulation of particle size distribution with a global aerosol model: contribution of nucleation to aerosol and CCN number concentrations
particle size distribution global aerosol model aerosol CCN number concentrations
2009/11/9
An advanced particle microphysics model with a number of computationally efficient schemes has been incorporated into a global chemistry transport model (GEOS-Chem) to simulate particle number size di...
The Communication of Meaning in Anticipatory Systems: A Simulation Study of the Dynamics of Intentionality in Social Interactions
anticipation social system meaning communication incursion double contingency
2010/4/7
Psychological and social systems provide us with a natural domain for the study of anticipations because these systems are based on and operate in terms of intentionality. Psychological systems can be...
Amplitude modulation and packet formation of Langmuir waves are commonly observed during a nonlinear interaction between electron beams and plasmas. In this paper, we briefly review the history of Lan...
Particle dispersion processes in two-dimensional turbulence:a comparison with 2-D kinematic simulation
Particle dispersion processes two-dimensional turbulence 2-D kinematic simulation
2009/11/2
We study numerically the comparison between Lagrangian experiments on turbulent particle dispersion in 2-D turbulent flows performed, on the one hand, on the basis of direct numerical simulations (DNS...
Combination of different types of ensembles for the adaptive simulation of probabilistic flood forecasts:hindcasts for the Mulde 2002 extreme event
adaptive simulation probabilistic flood forecasts extreme event
2009/10/30
Flood forecasts are essential to issue reliable flood warnings and to initiate flood control measures on time. The accuracy and the lead time of the predictions for head waters primarily depend on the...

NUMERICAL SIMULATION RAINFALL-RUNOFF PROCESS DAILY BASIS
2009/10/29
A digital model has been devcloped for the simulation of the rainfall -
runoff process of rural watersheds. Input data are daily values of prccipitation
and temperature together with mean monthly po...
Upper Layer Observations and Simulation Using Kraus and Turner's Model in the Gulf of Finland
Upper Layer Observations Simulation Kraus and Turner's Model Gulf of Finland
2009/10/29
There are strong seasonal variations in the depth of the thermocline and in the
sea surface temperature in the western part of the Gulf of Finland. A
numerical model, developed by Kraus and Turner, ...
A spatially distributed model for the simulation of snow accumulation and
melt is presented. Watershed information on topography, vegetation and soils
in digital terrain models (overlays) serve as t...
Application of Soil Water Flow Theory in Field Simulation
Application Soil Water Flow Theory Field Simulation
2009/10/28
A numerical model based on a finite difference approximation of the basic
differential equation for soil water flow is described. The equation includes a
sink term representing moisture extraction b...
Results of runoff simulations from various basins using a snowmelt runoff
model were analyzed in order to predict the accuracy of simulations in future
applications of the model. It was found that t...

Groundwater Response Conceptual Models Three Case Studies
2009/10/28
A conceptual runoff model is modified and applied to groundwater observations
in an unconfined till aquifer, a confined aquifer under a clay deposit and
a large unconfined esker aquifer. The results...
Stochastic Simulation of Evaporation Data for Australia
Stochastic Simulation Evaporation Data Australia
2009/10/28
Stochastic models are developed to simulate annual, monthly and daily
evaporation data for Australia. For annual and monthly synthesis, the
evaporation values are generated independently and depende...
