Quantifying sources of uncertainty in regional climate model scenarios for Ireland
This thesis develops a novel framework for model skill assessment and the generation of probabilistic future climate scenarios. Traditional approaches to model validation assume that skill in simulating the mean climate is a valid indicator of skill in modelling the climate system. However, without …

Coupling of Integrated Biosphere Simulator to Regional Climate Model version 3
… of Integrated Biosphere Simulator (IBIS) to Regional Climate Model version 3 (RegCM3), and an assessment of the coupled model (RegCM3-IBIS). RegCM3 is a 3-dimensional, primitive equation limited area model used throughout the world for seasonal predictability and regional climate studies. …

Atmospheric circulation and the surface mass balance in a regional climate model of Antarctica
Understanding the Earth's climate system and particularly climate variability presents one of the most difficult and urgent challenges in science. The Antarctic plays a crucial role in the global climate system, since it is the principal region of radiative energy deficit and atmospheric cooling. …

South Asian summer monsoon variability: a modelling study with the atmospheric regional climate model HIRHAM5
… on observations, reanalysis data and global model simulations have been carried out with the focus on monsoon active and break phases over India, the understanding of the monsoon intraseasonal variability is only in the infancy stage. Regional climate models could benefit the comprehension of …

The climatology of Thailand and future climate change projections using the regional climate model precis
The climate of Thailand has not been studied in as much depth as in other parts of continental Southeast Asia. The baseline climate of Thailand during 1961-1990 is first analysed using daily observational data from five surface stations, each representing a different region of Thailand, …

Regional climate model evaluations of long-term changes in total precipitation and high precipitation events
… variable to simulate in numerical weather/climate models. There are very limited studies on modeling evaluation of long-term trends in extreme precipitation events over the contiguous U.S. This study examines the downscaling skills of a state-of-the-art regional climate model, the Climate …

Sensitivity of Precipitation to Land-use Changes in a Regional Climate Model of West Africa
Limited water resources, climate change and food security needs in West Africa present a special set of challenges in the years to come as the population grows. An optimized irrigation scheme for agriculture can change regional climate by increasing rainfall in specific areas, possibly increasing …

INCORPORATING CLIMATE CHANGE PROJECTIONS INTO RISK MEASURES OF INDEX-BASED INSURANCE
We present a complete working example of using regional climate model projections to estimate the changing risks of temperature index-based insurance products defined for a series of locations in California. This region is a major agricultural producer for the US and the world. The climate model …

Direct and semi-direct aerosol effects on the southern African regional climate during the austral winter season
The regional climate model RegCM3 is used to investigate the direct and semi-direct aerosol effects on the southern African climate during the austral winter season (June-September). The sensitivity of simulated aerosol-climate effects to different biomass burning inventories, boundary conditions …

Climate extremes over the Mid-Atlantic states: a regional approach
… as global temperatures rise, established climate ranges may no longer be applicable, as historic records for extremes such as heat waves and floods may no longer accurately predict the changing future climate. To assess extremes (present-day and future) over the contiguous United States, I …

Future changes in extreme events in Mozambique as simulated using the PRECIS regional climate modeling system
Future climate change is generally believed to lead to an increase in climate variability and inthe frequency and intensity of extreme events. Mozambique is well known for its occurrenceof severe weather and extreme climate events such as floods, tropical cyclones and droughts.Such events have …

Sea surface temperature anomalies in the South Indian ocean : observations and atmospheric modelling
… to this phenomenon, this study uses the MM5 regional climate model in which the model is forced with a warm pole SST anomaly south of Madagascar.

Understanding past and future changes in northern Fennoscandian snow cover.
… of field measurements, remote sensing data and regional climate model outputs were used to study recent and projected future changes in Northern Fennoscandian snow cover. The research questions considered in this thesis are: What are the uncertainties in remote sensing and climate modelling …

The Effects of Anthropogenic Warming on Changes of Extreme Precipitation Over Kansas City Metropolitan Area
When the Intergovernmental Panel on Climate Change (IPCC) Special Report Global Warming of 1.5°C was released in 2018 it postulated about the devastating effects of a 2° C increase in global temperature, based on projections of coarse resolution global climate models (GCMs). While GCMs are useful …

Application de la télédétection à l'analyse de la variabilité climatique des régions boréales et subarctiques du Canada et à la validation du modèle régional canadien du climat
… present thesis fits within the scope of global climate change analysis. It focuses on two main areas of interest, namely the study of recent past climate over the last few decades and the development of tools for modeling future climate. Study of past climate.The first part of this thesis deals …

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 …

A test for a see-saw oscillation between the Amazon and Congo basins using regional climate modeling
… by Eltahir et al., using satellite data of regional rainfall (Simpson et al. 1988), and indirectly through changes in river flow measurements (Amarasekera et al. 1977) during the last century. However, little work has been done to study this see-saw effect through the use of climate models. …
