Invariant Manifolds of a Toy Climate Model
… glacier/temperature interaction of an idealized climate was studied. Self sustained oscillation of the autonomous equation was used to model the internal mechanisms that could produce these fluctuations. Periodic parametric modulation of a damped internal oscillation was used to model periodic …

Essays on Urban Climate Model Evaluation and Application
… thermal modification of the near surface climate was proposed within the field to bring greater rigor, clarity and transferability to observations made within urban areas. The Local Climate Zone (LCZ) approach has since been applied in multiple cities globally, which has demonstrated its …

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
… 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. IBIS is a …

Biosphere-atmosphere interaction in a one-dimensional climate model of the tropics
In this study, we develop a one-dimensional model of the tropics which includes two way interaction between the biosphere and the atmosphere. The model integrates a radiative-convective equilibrium model of the atmosphere, a land surface model including plant growth and competition and a monsoon …

Conceptualising and quantifying the nonlinear, chaotic climate: implications for climate model experimental design
Uncertainty in climate system initial conditions (ICs) is known to limit the predictability of future atmospheric states. On weather time scales (i.e. hours to days), the separation between two atmospheric model trajectories, initially "indistinguishable" (compared to unavoidable uncertainties) …

A reduced-form statistical climate model suitable for coupling with economic emissions projections
In this work, we use models based on past data and scientific analysis to determine possible future states of the environment. We attempt to improve the equations for temperature and greenhouse gas concentration used in conjunction with the MIT Emissions Prediction and Policy Analysis (EPPA) model …

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. …

Using high-resolution modelling to improve the parameterisation of convection in a climate model
… convective clouds. Through this work a 1D cloud-model was derived from first principles to represent the vertical profile of individual convective clouds. A microphysics framework was implemented to ensure identical behaviour in LES and cloud-model integration where the microphysical processes …

Greenhouse climate model : an aid to estimate the influence of supplemental lighting on greenhouse climate
… and because of the unique weather, a greenhouse climate model is advisable to analyze various design solutions. Iceland's weather has a seasonal change in the length of day and night, creating unique weather phenomena. In midwinter, there is a period where darkness prevails. In midsummer, …

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 …

Analyzing recent latitudinal and seasonal changes in simulated atmospheric temperatures from a global chemistry-climate model
… of warming for fingerprinting anthropogenic climate change using satellite data and the CMIP5 multi-model ensemble over 1979-2016. They identify the first seasonal fingerprint in the northern hemisphere annual cycle and structure of warming, but do not specify what forcing agent (e.g. ozone, …
