Analysis of the impact of climate change on groundwater related hydrological fluxes: a multi-model approach including different downscaling methods
groundwater related hydrological fluxes multi-model approach
2011/1/7
Climate change related modifications in the spatio-temporal distribution of precipitation and evapotranspiration will have an impact on groundwater resources. This study presents a modelling approach ...
Meteorological uncertainty and rainfall downscaling
Meteorological uncertainty rainfall downscaling
2009/11/3
We explore the sources of forecast uncertainty in a mixed dynamical-stochastic ensemble prediction chain for small-scale precipitation, suitable for hydrological applications. To this end, we apply th...
Comparison of data-driven methods for downscaling ensemble weather forecasts
statistical downscaling model evolutionary polynomial regression medium range forecast
2009/4/29
This study investigates dynamically different data-driven methods, specifically a statistical downscaling model (SDSM), a time lagged feedforward neural network (TLFN), and an evolutionary polynomial ...
Utility of daily vs. monthly large-scale climate data：an intercomparison of two statistical downscaling methods
bias correction and spatial downscaling General Circulation Model climate data
2009/4/29
Downscaling of climate model data is essential to local and regional impact analysis. We compare two methods of statistical downscaling to produce continuous, gridded time series of precipitation and ...
Statistical atmospheric downscaling for rainfall estimation in Kyushu Island, Japan
atmospheric downscaling precipitation rainfall
2009/3/23
The present paper develops linear regression models based on singular value decomposition (SVD) with the aim of downscaling atmospheric variables statistically to estimate average rainfall in the Chik...

Annual series of three stochastic rainfall model parameters — the seasonal wet day amount (or intensity)
A geostatistical approach to multisensor rain field reconstruction and downscaling
Reconstruction downscaling
2009/3/23
A rain field reconstruction and downscaling methodology is presented, which allows suitable integration of large scale rainfall information and rain-gauge measurements at the ground. The former data ...
Downscaling rainfields in space and time, using the String of Beads model in time series mode
Space-time rainfield modelling
2009/3/23
The String of Beads model is a space-time model of rainfields measured by weather radar. It is here driven by two auto-regressive time series models, one at the image scale, the other at the pixel sca...
Impact analysis of climate change for an Alpine catchment using high resolution dynamic downscaling of ECHAM4 time slices
coupled climate-hydrology simulations dynamic downscaling
2009/3/11
Global climate change affects spatial and temporal patterns of precipitation and so has a major impact on surface and subsurface water balances. While global climate models are designed to describe cl...
