WRF-based dynamical downscaling over High Mountain Asia
… in this thesis. The HAR v2 was generated by dynamical downscaling of ERA5 reanalysis data using the Weather Research and Forecasting Model (WRF). The HAR v2 provides atmospheric data at 10 km grid spacing and hourly temporal resolution. It is currently available from 2000 to 2020 and will be …

Regional dynamical downscaling and analysis of water balance across different regions and time scales
Employing the regional dynamical downscaling (RDD) technique, we can enhance the spatial and temporal resolution of global reanalysis and general circulation model (GCM) data, providing improved data for studying ecological processes. This method ensures physical validity of the data, albeit at …

Data assimilation and dynamical downscaling of remotely-sensed precipitation and soil moisture from space
… major components: (1) a framework for dynamic downscaling of satellite precipitation products using the Weather Research and Forecasting (WRF) model with four-dimensional variational data assimilation (4D-Var) and (2) a variational data assimilation system using spatio-temporally varying …

Extreme events over the contiguous United States portrayed in a CESM-WRF dynamical downscaling framework
A dynamical downscaling framework is adopted to explore historical (1950-1999) and projected (2050-2099) behavior of extreme precipitation (PR), maximum temperature (TMAX) and minimum temperature (TMIN) events within the contiguous United States. Compared to reanalysis data, simulations represent …

Climate change and hazardous convective weather in the United States: Insights from high-resolution dynamical downscaling
… (WRF) model to produce high-resolution, dynamically downscaled simulations for the continental United States under historical (1971--2000) and future (2071--2100) climate periods using GCM data provided by the Geophysical Fluid Dynamic Laboratory Climate Model version 3 (GFDL-CM3). Model …

MODELLING DRY AND WET EXTREMES OVER THE CANADIAN PRAIRIE PROVINCES BASED ON THE DYNAMICAL DOWNSCALING AND MULTIVARIATE FREQUENCY ANALYSIS APPROACHES
The primary tools to assess climate change are the Atmosphere–Ocean General Circulation Model (AOGCM) or Regional Climate Model (RCM) transient climate change simulations. Currently, RCMs offer higher spatial resolution than AOGCMs and therefore are preferred for assessing impact of climate change …

Bias Correction and Downscaling of Climate Model Outputs Required for Impact Assessments of Climate Change in the U.S. Northeast
… impact analysis of climate change. Although downscaling of GCM outputs can be performed by dynamical downscaling using Regional Climate Models (RCMs), it requires large computational capacity. When daily climate data from multiple GCMs are required to be downscaled, dynamical downscaling may …

Preparation for CWRF downscaling climate prediction over Pakistan: development of iCWPS surface processing and analysis of regional precipitation teleconnection
… is aimed at the optimal domain definition with dynamical downscaling as a condition for CWRF simulation requirement.

Climate Change and Atlantic salmon (Salmo salar): Changes in Flow and Freshwater Habitat in the Burrishoole Catchment
… emission scenarios, driving GCMs and statistical/dynamical downscaling models; in addition, three different rainfall-runoff models (HBV, HYSIM and TOPMODEL) were employed – integrating across both structural and parameter uncertainty. By considering multiple model pathways this study attempts to …

Evaluations of historical and projected high-resolution dynamically downscaled ensemble over the continental United States
… To rectify this limitation, a technique known as dynamically downscaling was introduced to better resolve these small-scale processes and provide society with quantitative evaluation of regional climate risks associated with a warming climate. This dissertation uses an ensemble of dynamically …
