Constraining storm-scale forecasts of deep convective initiation with surface weather observations
Successfully forecasting when and where individual convective storms will form remains an elusive goal for short-term numerical weather prediction. In this dissertation, the convective initiation (CI) challenge is considered ... -
Reconstructing Arctic Sea Ice in the Common Era
Arctic sea ice concentrations have undergone rapid declines in recent decades. Many factors have been shown to contribute to this decline, and much of it has been attributed to greenhouse gas forcing and natural variability. ... -
Reconstructing Coupled Atmosphere-Ocean Variability Over the Last Millennium
Coupled interactions between oceans and the atmosphere are fundamental to low-frequency variability of the Earth System. While the instrumental record provides an account of this coupled variability over time, the length ... -
Reconstructing Past Climate by Using Proxy Data and a Linear Climate Model
In this work we improve the skill of climate field reconstructions (CFRs) through the use of an online paleoclimate data assimilation (PDA) method within the Last Millennium Reanalysis framework (LMR). A computationally ... -
The Promise of Sea Ice Thickness: A Data Assimilation Application for Modern Arctic Climate
The significant role of sea ice in local and global climate and human-environment interactions in a rapidly changing world, necessitates a solid understanding of its recent and future states. Future Arctic sea ice extent ...
