Dynamical Global Downscaling of Global Reanalysis
Monthly Weather Review, 2008 Abstract With the aim of producing higher-resolution global reanalysis datasets from coarse-resolution reanalysis, a global version of the dynamical downscaling using a global spectral model is developed. A variant of spectral nudging, the modified form of scale-selective bias correction developed for regional models is adopted.

Impacts of Spectral Nudging Parameters on Dynamical Downscaling in Summer over Mainland China
Frontiers in Earth Science, 2020 Spectral nudging is an important method of improving the effectiveness of dynamical downscaling in the Weather Research and Forecasting model (WRF). However, spectral nudging is sensitive to nudging parameters, and most related research has typically ...

Dynamical Downscaling of Climate Simulations in the Tropics
Geophysical Research LettersAbstract The long‐existing double‐Intertropical Convergence Zone (ITCZ) problem in global climate models (GCMs) hampers accurate climate simulations in the tropics. Using a regional climate model (RCM) over the tropical and sub‐tropical Atlantic with a horizontal resolution of 12 km and explicit convection, we develop a bias‐corrected

Dynamical influences of precipitation assimilation on regional downscaling [PDF]
Geophysical Research Letters, 2007 Precipitation assimilation has previously been found to be useful for improving regional climate model simulations of the surface water and energy cycles. Here we show that upper‐level dynamical features are also better simulated. In particular, noticeable improvements in the intensity and location of the subtropical upper‐level westerly jet and ...

Tellus: Series A, Dynamic Meteorology and Oceanography, 2016 Assessments of local-scale windstorm hazard require highly resolved spatial information on wind speeds and gusts. In this study, maximum (peak) sustained wind speeds on a 3-km horizontal grid over Switzerland are obtained by dynamical downscaling from ...
