STATISTICAL MODELLING AND ANALYSIS FOR REGIONAL CLIMATE CHANGE
… models (GCMs) are often used to inform climate change information, however, due to their coarse spatial resolutions, downscaling approaches are often relied to transit the coarser-scale GCM outputs to higher resolutions. Multivariate multisite weather generators (MMWGs) are appealing …

On surface versus atmospheric forcing in regional climate simulations
… to contrast surface and atmospheric forcing in regional climate simulations. Results of the first paper showed that a transient increase in soil moisture enhanced domain total rainfall. The increase in soil moisture enhanced local rainfall when the lower atmosphere was thermally unstable and …

Transferability of regional climate models over different climatic domains
In the continuing quest to improve climate model predictions to meet the increasing demand for knowledge on the regional effects of global climate change, it is pertinent to increase our understanding of how the underlying processes of climate are represented in the models we use to make these …

Investigating regional climate drivers, wildfire mitigation, and air quality responses.
Climate change is increasing wildfire activity in many regions, amplifying air pollution impacts in densely populated areas. This dissertation studies climate drivers, wildfire mitigation, and urban air quality responses to better inform integrated environmental management. Using observations from …

California in the greenhouse: regional climate policies and the global environment
This thesis explores how climate policy is developing at sub-national or “regional” scales of decision-making. It considers local-global connections on both the science and the politics of climate change by investigating four main research questions as they pertain to regional climate action: What …

Quantifying sources of uncertainty in regional climate model scenarios for Ireland
… 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 information about how errors arise, conclusions cannot be …

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’, …

Föhn winds on South Georgia and their impact on regional climate
… remote Southern Ocean. The island’s subantarctic climate is controlled by its location and steep orography; with 19 peaks over 2000m and situated within a belt of strong westerly winds South Georgia acts as an effective barrier to the winds that impinge upon it. Since the 1920s, average summer …

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. …

A standardized framework for evaluating the skill of regional climate downscaling techniques
Regional climate impact assessments require high-resolution projections to resolve local factors that modify the impact of global-scale forcing. To generate these projections, global climate model simulations are commonly downscaled using a variety of statistical and dynamical techniques. Despite …

The evaluation of NARCCAP regional climate models using the North American Regional Reanalysis
Understanding the extent of future climate change is highly dependent on the use of climate models to assess the degree and rate of change. More recently, dynamic downscaling has been employed with the use of regional climate models (RCMs) as an alternative to statistical downscaling. However, …

An Actor-Centred Approach to Overcoming Barriers in Regional Climate Change Adaptation Decision-Making
Ilmastonmuutoksen vaikutukset voivat huomattavasti vaihdella eri alueiden välillä, mikä vaatii alueellista päätöksentekoa liittyen parhaisiin tapoihin hillitä niiden haitallisia seurauksia ja tavoitella mahdollisia hyötyjä. Tästä huolimatta, toimijat voivat kohdata lukuisia esteitä …

Applying regional climate change projections for spatio-temporal risk analyses of vector-borne diseases
… der Arbeit werden die Einsatzmöglichkeiten von regionalen Klimamodellen zur Gefährdungsabschätzung anhand verschiedener Fallbeispiele aufgezeigt. Deren Nutzen und Einsatzmöglichkeiten werden einführend aufgeführt. Für die Risikoanalysen werden regionalen Klimamodelle REMO und COSMO-CLM …

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. …

Modelling the impact of urbanisation on the regional climate of the Greater London area
Urban areas have well documented effects on climate, such as the urban heat island effect, reduction of wind speeds, enhanced turbulence and boundary layer heights, and changes in cloud cover and precipitation. This PhD examines the impact of the urban surface on the major agglomeration of London …

South Asian summer monsoon variability: a modelling study with the atmospheric regional climate model HIRHAM5
… variability is only in the infancy stage. Regional climate models could benefit the comprehension of monsoon breaks by its resolution advantage. This study investigates moist dynamical processes that initiate and maintain breaks during the South Asian summer monsoon using the atmospheric …

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 …

Investigating the link between southern African droughts and global atmospheric teleconnections using regional climate models
… This study evaluates the capability of Regional Climate Models (RCMs) in simulating the Southern African droughts. It uses the Standardized Precipitation-Evapotranspiration Index (SPEI, computed using rainfall and temperature data) to identify 3-month droughts over Southern Africa, and …

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 …
