Estimating the water budget of extratropical cyclones with the precipitation efficiency
Estimating the water budget of three mid-latitude extratropical cyclones is attempted from the perspective of the precipitation efficiency (PE), using a method proposed for the study of convective columns. Using a lagrangian, system-relative volume centered on the surface low pressure, each cyclone …

Collective risk modelling of multivariate compound events: correlation of aggregate wind and precipitation in European extratropical cyclones
Extratropical cyclones cause both extreme wind and precipitation in Europe, which can result in substantial aggregate insurance losses. Understanding the relationship between these aggregates can potentially aid insurers in their portfolio management. This thesis uses annually aggregated wind and …

Synoptic weather systems over Antarctic sea ice: understanding the link between extratropical cyclones and extreme variability in Antarctic sea-ice concentration
Extratropical cyclones and atmospheric rivers are key drivers in transporting extreme heat and moisture to the poles. Previous studies have shown that extratropical cyclones can promote change in sea-ice concentration at a synoptic scale, however, the extreme variability in synoptic-scale sea-ice …

Extratropical storm tracks and the mean state of the atmosphere
… on the high-frequency phenomena that form the extratropical atmospheric circulation are uncertain. The extratropical storm tracks, regions of frequent extratropical cyclones, dominate weather in the extratropics, affecting the lives and livelihoods of billions of people. The results presented …

An Overview and Evaluation of SynthETC: A Statistical Model for Extra-Tropical Cyclones
<p>Extratropical cyclones (ETCs) are the most common weather phenomena affecting the United States, Canada, and Europe. They can pose serious hazards over large swaths of area. In this thesis, a statistical model of ETCs, called SynthETC, is discussed. The model accounts for the for genesis, track …

Identifying Dry Intrusion Outflows in Present and Future Climates with Machine Learning
… are one of the key airstreams associated with extratropical cyclones. They are known to exacerbate the impacts of mid-latitude weather through mixing with the boundary layer and enhancing atmosphere-surface interactions. Currently, DIs are identified with Lagrangian trajectory analysis, which …

Statistical models for extreme weather events
… in winter is from the passage of low-pressure extratropical cyclones from the North Atlantic. The second aim of this thesis is to quantify the risk associated with extreme wind speed events, which we call windstorms, arising from an extratropical cyclone system. First, we develop a model …

Enhancing Compound Flood Modeling through Efficient Data-Driven, Physics-based, and Transfer Learning Frameworks
… systems typically occurs during tropical and extratropical cyclones, yet its evolution in space and time remains difficult to predict using data-driven or physics-based modeling approaches. Compound flooding arises from either concurrent or successive occurrences of flood drivers and their …

Modification of Precipitation in Mid-Latitude Cyclones Passing over a Coastal Mountain Range
As mid-latitude cyclones pass over a coastal mountain range, the processes producing their clouds and precipitation are modified, leading to considerable spatial variability in precipitation amount and composition. Surface, radar, and aircraft observations from the 2015-16 Olympic Mountains …

Understanding Coastal and Inland Hydrometeorological Hazards Produced by Extratropical and Tropical Cyclones along the East Coast of the United States
… the characteristics of the storm types, such as extratropical cyclones (ETCs) and tropical cyclones (TCs), that produce such hazards. Through the use of observational and reanalysis data, the work herein utilizes a cyclone-hazard association algorithm and extreme value analysis to assess the …
