Three-Dimensional Volume Averaged Soil-Moisture Transport Model: A Scalable Scheme for Representing Subgrid Topographic Control in Land-Atmosphere Interactions
… A conjunctive surface-subsurface flow model at a large scale, a 1-D Diffusion Wave (DW) surface flow model interacting with the 3-D VAST model, is developed for the comprehensive terrestrial water and energy predictions in LSMs. For the implementation of the model, the mixed numerical …

The use and application of performance metrics with regional climate models
… objective and robust approaches to evaluate regional climate model (RCM) historical skill using performance metrics and to provide guidance to relevant groups as to how best utilise these metrics. Performance metrics are quantitative, scalar measures of the numerical distance, or ’error’, …

Extreme value theory: Applications to estimation of stochastic traffic capacity and statistical downscaling of precipitation extremes
… cross validation procedure reveals the GEV model, using both censored and observed capacity data, is suitable for probabilistic prediction. To overcome the uncertainty associated with a high number of censored values at one location, a hierarchical model was developed to share information …

Assessment of the impacts of climate change, land cover transition, and internal climate variability on the hydrology of a forested watershed
In this study, the impacts of climate and land cover (LC) changes on the hydrologic processes of the Batchawana watershed in Central Ontario are assessed. Batchawana is a snow-dominated forested watershed with coniferous, deciduous and mixed trees and numerous small lakes. A semi-distributed …

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 …

The development of Intensity Duration Frequency curves under climate change considerations using Remote Sensed rainfall data in Uganda
… (IDF) curves are essential for climate-resilient design, yet their development is constrained by the lack of long-term subdaily rainfall records. The challenge addressed in this research is the limited availability of subdaily and long-term daily rainfall data required to …

NARCCAP Model Assessment and Future Projections For the Southeast United States
<p>Global climate models (GCMs) provide most climate change projections, but their coarse resolution must be downscaled to more local scales in order to conduct meaningful climate impact assessments. This dissertation investigates dynamically downscaled regional climate model (RCM) output from the …

Potential impacts of climate change on hydrological droughts in the Limpopo river basin
Climate change possibly intensifies hydrological droughts and reduces water availability in river basins. Despite this, most research on climate change effects in southern Africa has focused exclusively on meteorological droughts. This thesis projects the potential effect of climate change on the …

Influence of the North Atlantic Subtropical High on Summer Precipitation over the Southeastern United States
… intensified, leading to more frequent and severe climate extremes. However, the processes that have caused such enhanced climate variability have been poorly understood. By analyzing atmospheric hydrological cycle, diagnosing atmospheric circulation dynamics, and performing regional climate …

Understanding a high resolution regional climate model's ability in simulating tropical East Africa climate variability and change
… potential benefits of increasing resolution in regional climate models in the simulation of climate variability and change over East Africa. This study is based on two high resolution regional climate simulations with a horizontal resolution of 50km and 10km, respectively. These represent …
