AI-informed model analogs for subseasonal-to-seasonal prediction
Subseasonal-to-seasonal forecasting is crucial for public health, disaster preparedness, and agriculture, and yet it remains a particularly challenging timescale to predict. We explore the use of an interpretable AI-informed model analog forecasting approach, previously employed on longer …

Evaluating CFSv2 Subseasonal Forecast Skill with an Emphasis on Tropical Convection
The deterministic predictive skill of CFSv2 is analyzed with respect to lead time and temporal averaging period. We also examine the spatial distributions of error and bias for synoptic-scale parameters and the impacts of ENSO on forecast skill. The errors in a small CFSv2 ensemble forecast …

Subseasonal to seasonal prediction and predictability of extreme and severe weather
This dissertation investigates the prediction and predictability of extreme and severe weather on the sub-seasonal to seasonal (S2S) timescale while exploring physical mechanisms that result in successful statistical prediction of atmospheric blocking, extreme temperatures, and severe weather …

Application of neural networks to subseasonal to seasonal predictability in present and future climates
… is known for its lack of predictability on subseasonal to seasonal timescales (S2S; 2 weeks to a season). Yet accurate predictions on these timescales provide crucial, actionable lead times for agriculture, energy, and water management sectors. Fortunately, specific Earth system states – …

Toward better subseasonal-to-seasonal prediction: physics-oriented model evaluation and predictability of tropical cyclones
"Skillful subseasonal-to-seasonal (hereafter S2S; 10 days - 12 weeks) prediction can greatly benefit decision-making on resource management and agricultural planning that falls into the weekly to seasonal time ranges. The S2S prediction, bridging the traditional weather forecasting and climate …

On the observed and simulated responses of the extratropical atmosphere to surface thermal forcing
… SST anomalies and the atmospheric circulation on subseasonal timescales and 2) providing a new, simplistic framework for interpreting the atmospheric response to surface thermal forcing across the globe in an idealized global climate model. In the first theme of this thesis, observational analyses …

Variation in the Bimodal Precipitation Regime of Southern Nevada, USA Measured in Tree-Ring Isotopes
… in the α-cellulose of tree rings to interpret subseasonal climatic patterns for the 2015 and 2016 growing season. Finally, a novel index calculated as the difference between the δ13C of α-cellulose in the latewood and earlywood (δ13CDIFF = latewood - earlywood) portions of a tree ring was …
