Climate sensitivity study with energy balance models
In this thesis, the sensitivity of the Earth's climate is studied by modeling past climatic variations with two-dimensional seasonal energy balance model. This thesis consists of two parts. The first part is a study of the interaction between the seasonal cycle and the small ice cap instability, …

An Investigation Of Cloud Processes Relevant To Climate Sensitivity
… source of uncertainty in predicting the Earth's climate response to CO2 radiative forcing. Various global climate models estimate that this response amplifies the initial CO2 forcing by a factor between 2 and 5. The research in this dissertation aims to better understand cloud processes that have …

Incorporating Climate Sensitivity for Southern Pine Species into the Forest Vegetation Simulator
… forests have led to increasing calls to address climate change effects on forest vegetation in management and planning applications. The objectives of this project are to model contemporary conditions of soils and climate associated with the presence or absence and abundance of five southern pine …

Constraining uncertainty in climate sensitivity : an ensemble simulation approach based on glacial climate
Uncertainty about the sensitivity of the climate system to changes in the Earth’s radiative balance constitutes a primary source of uncertainty for climate projections. Given the continuous increase in atmospheric greenhouse gas concentrations, constraining the uncertainty range in such type of …

Evaluating the relationship between the temperature response to volcanic aerosols and climate sensitivity
Climate sensitivity is an important concept in climate science, but its estimated value has considerable uncertainty. Some previous studies have argued for a link between the temperature response to volcanic radiative forcing and climate sensitivity. Bender et al. (2010) showed that equilibrium …

Incorporating Climate Sensitivity for Eastern United States Tree Species into the Forest Vegetation Simulator
Detecting climate-induced effects in forest ecosystems become increasingly important as more evidence of greenhouse-gas-related climate change were founded. The Forest Vegetation Simulator (FVS) is an important growth and yield model used to support management and planning on public forest lands …

Revisiting the importance of a Southern Ocean pattern effect
… radiative feedbacks in time and hence, determine climate sensitivity. We revisit their argument in current generation climate models: We quantify the time evolution of local atmospheric stability, clouds, and their local and global radiative effects as the Southern Ocean warming is catching up …

Integration of seasonal forecast information and crop models to enhance decision making in small-scale farming systems of South Africa
Climate variability threatens agricultural productivity and household food security, amongst small-scale farmers of South Africa. Managing climate variability is challenging due to the variation of climate parameters and the difficulty in making decisions under such conditions. Integrated seasonal …

Application of the hector-brick reduced complexity earth system model for probabilistic climate projection
Probabilistic climate assessments require robust characterizations of decision-relevant uncertainties. Reduced complexity climate models can be useful tools for quantifying uncertainty, given their flexibility, computational efficiency, and the ability to link these models with large-ensemble …

Imprecise probability analysis for integrated assessment of climate change
… of uncertainty in the integrated assessment of climate change. Our work is motivated by the fact that uncertainty about climate change is pervasive, and therefore requires a thorough treatment in the integrated assessment process. Classical probability theory faces some severe difficulties in …

Parallel multigrid for large-scale least squares sensitivity
… two approaches for efficiently computing the "climate" (long- time average) sensitivities for dynamical systems. Computing these sensitivities is essential to performing engineering analysis and design. The first technique is a novel approach to solving the "climate" sensitivity problem for …

The organic nature and atmosphere-climate dependency of nitrogen loss from forest watershed ecosystems
… and external forcing from the atmosphere and climate can regulate the dynamics of nitrogen (N) loss from forest watersheds. I address three major gaps in our understanding of the global N cycle: 1) the role of dissolved organic N (DON) in internal N cycling in low-N ecosystems; 2) The …

Global heat balance without and with solar radiation management
… variable solar irradiance are considered. The ""climate sensitivity"" of global average temperature response to these influences accounts for the ""ice albedo"" effect of global average temperature changes on absorption of short wavelength radiation and the influence of temperature changes on …

Episodic Recruitment and Climate Analysis of Ponderosa Pine on the Palmer Divide, Eastern Colorado
… Eastern Colorado, to determine the relative climate sensitivity of the two sites, and the extent to which climate or other factors may have influenced recruitment at the sites. The results of the tree-ring analysis suggest that ponderosa pines in more the easterly site lower elevation …

Climatic and edaphic influences on the radial growth of eastern redcedar (Juniperus virginiana), Smoke Hole Canyon, West Virginia
… tree-ring records has been used to reconstruct climate conditions at the local, regional, and global scales. Dendrochronology, the study of tree rings, has typically focused on locations where trees are limited by a single climatic variable (i.e. temperature or moisture availability) at the …
