Simulation of dust aerosol and its regional feedbacks over East Asia using a regional climate model
dust aerosol regional feedbacks East Asia regional climate model
2009/3/13
The ICTP regional climate model (RegCM3) coupled with a desert dust aerosol model is used to simulate the net radiative forcing (short-wave and long-wave) and related climate effects of dust aerosols ...
Methane plume over south Asia during the monsoon season: satellite observation and model simulation
Methane plume south Asia monsoon season
2009/3/13
Satellite retrievals of methane (CH4) using the Atmospheric Infrared Sounder (AIRS) on the EOS/Aqua platform from 2003–2007 show a strong, plume-like enhancement of CH4 in the middle to upper troposph...
Simulation of the climate impact of Mt. Pinatubo eruption using ECHAM5 – Part 1: Sensitivity to the modes of atmospheric circulation and boundary conditions
climate impact Mt. Pinatubo eruption ECHAM5 atmospheric circulation boundary conditions
2009/3/12
The eruption of Mt. Pinatubo in the Philippines in June 1991 was one of the strongest volcanic eruptions in the 20th century and this well observed eruption can serve as an important case study to und...
Reduction of Monte-Carlo simulation runs for uncertainty estimation in hydrological modelling
parameters calibration GLUE Monte-Carlo simulation
2009/3/12
Monte-Carlo (MC) simulation based techniques are often applied for the estimation of uncertainties in hydrological models due to uncertain parameters. One such technique is the Generalised Likelihood ...

Simulation of trace gas convective clouds - Liquid phase processes
2009/3/12
A two-dimensional dynamic cloud model with detailed microphysics and a spectral treatment of gas scavenging was used to simulate trace gas vertical redistribution in precipitating continental and mar...
Simulation of flood reduction by natural river rehabilitation using a distributed hydrological model
river rehabilitation flood reduction distributed hydrological modelling WetSpa
2009/3/11
The effects of river rehabilitation on flood reduction in the Steinsel sub-basin of the Alzette River basin, Grand-Duchy of Luxembourg, are discussed; the rehabilitation measures include planting and ...
A condensed-mass advection based model for the simulation of liquid polar stratospheric clouds
condensed-mass advection based model liquid polar stratospheric clouds
2009/3/10
We present a condensed-mass advection based model (MADVEC) designed to simulate the condensation/evaporation of liquid polar stratospheric cloud (PSC) particles. A (Eulerian-in-radius) discretization ...
A Numerical Simulation of the Onset of El Niño
Numerical Simulation Onset of El Niñ o
2009/3/7
El Niño may be defined oceanographically as a massive influx of warm water into the coastal region of Ecuador and Peru. We have tested the hypothesis that these rare events occur after a substa...
Numerical Simulation of the Arctic Ocean Circulation
Numerical Simulation Arctic Ocean Circulation
2009/3/7
The circulation of the Arctic Ocean and Greenland Sea is simulated using the 1969 numerical model of Bryan and Cox. The coastline and bottom topography of the region are resolved by a 110 km horizonta...
A Three-Dimensional Simulation of Coastal Upwelling off Oregon
A Three-Dimensional Simulation Coastal Upwelling
2009/3/7
The wind driven, x-y-t, two-layer β-plane numerical model developed by Hurlburt (1974) is used to investigate the effects of a bottom topography and coastline configuration, like that off Oregon, on t...

Numerical Simulation Gulf Stream Mid-Ocean Eddies
2009/3/7
The circulation of the western North Atlantic is simulated with a primitive equation model that has 5 levels and a horizontal grid size of 37 km. The idealized model domain is a rectangular basin, 300...
Snowmelt runoff from northern alpine tundra hillslopes: major processes and methods of simulation
subsurface runoff alpine tundra
2009/3/6
In northern alpine tundra, large slope gradients, late-lying snow drifts and shallow soils overlying impermeable substrates all contribute to large hillslope runoff volumes during the spring freshet. ...
Comparative simulation of the nitrogen dynamics using the INCA model and a neural network analysis: implications for improved nitrogen modelling
catchment runoff nitrogen
2009/3/6
Continuing deposition of nitrogen in forested catchments affects stream and groundwater quality. However, the dependence of nitrogen dynamics on climatic and hydrological boundary conditions is still ...
