On quasi-periodic Baroclinic variability in the extratropical circulation
… studies have demonstrated that large-scale extratropical wave activity is characterized by quasi-periodic behavior on timescales of 20-30 days, particularly in the Southern Hemisphere. This phenomenon has been termed the Baroclinic Annular Mode (BAM), and is responsible for the modulation of …

The impact of Arctic amplification on the extratropical jets
Since the 1990's, greenhouse gas forcing has warmed the Arctic at twice the rate of lower latitudes, coinciding with a dramatic decline in Arctic sea ice extent. This manifestation of climate change has ignited a lively and ongoing debate regarding if Arctic warming will significantly influence …

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 …

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 …

Generalized Barotropic Models for Studying the Low -Frequency Variability of the Extratropical Atmosphere
Finally, the generalized model is scrutinized in terms of its normal, adjoint, optimal and singular modes. It is found that the modes of the empirically modified model are more stable than the ones of the barotropic model. Also the modified barotropic optimal modes are more difficult to excite than …

On the observed and simulated responses of the extratropical atmosphere to surface thermal forcing
… in understanding the role of the ocean in extratropical air-sea interaction. While the influence of the extratropical ocean can be relatively subtle and difficult to detect, recent studies have provided a growing body of evidence suggesting that the extratropical ocean has a potentially …

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 …
