Midlatitude Storm Track Response to Increased Greenhouse Warming
Storm tracks play a major role in regulating the precipitation and hydrological cycle in midlatitudes. The changes in the location and amplitude of the storm tracks in response to global warming will have significant impacts on the poleward transport of heat, momentum and moisture and on the …

The Effects of Diabatic Heating on Storm Track Dynamics
… diabatic heating in Northern Hemisphere winter storm tracks are studied in the context of a nonlinear primitive equation model with vertical and horizontal resolution adequate to capture shallow, short wavelength baroclinic waves. The model is forced by realistic orography and diabatic processes …

A Diagnostic and Dynamical Study of the Midwinter Minimum of the Pacific Storm Track
"In NH winter, the Pacific storm track tends to reach its maximum intensity during early and late winter, leaving a distinct minimum in January, which is known as ""midwinter minimum"" (MWMIN) of the Pacific storm track. The main objective of this study is to explain the origin of MWMIN from the …

Extratropical storm tracks and the mean state of the atmosphere
… 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 in this thesis connect changes in the mean state of the atmosphere to …

Mechanisms of Interactions between Aerosol Physics and Atmospheric Dynamics
… wave activity across the tropical Atlantic storm tracks, while the variability of smoke particles from the South African biomass burning is attributed by low-frequency oscillations of baroclinic instability of the region. We proposed that the impacts of Saharan Air Layer (SAL) on large-scale …

Interannual variability in cloudiness, sea surface temperature, and atmospheric circulation over the midlatitude North Pacific during summer
… suggesting coincident meridional shifts in the storm track and region of strong SST gradient. This suggests synoptic activity also plays a role in MSC variability.

The effects of ocean eddies on tropical cyclones
… by a cyclonic eddy that was south of the typhoon track. The 3DPWP model outputs with and without an eddy are compared with observations made during the field campaign. These observations are compared to model outputs with eddies in a series of positions right and left of the storm track in order …

Speleothem-based hydroclimate proxies and Late-Quaternary paleoclimate in the Western Mediterranean
… mid-latitude westerlies and the Mediterranean storm track. These findings provide clear evidence for the significant role of mid-latitude westerlies in driving humid conditions in northernmost Africa over the past 300,000 years. In the final manuscript, a stalagmite record (LAM-2-1) from …

An Overview and Evaluation of SynthETC: A Statistical Model for Extra-Tropical Cyclones
… The model accounts for the for genesis, track path, termination, and intensity of statistically generated ETCs. Genesis is modeled as a Poisson process, whose mean is determined by climate and historical information. Tracks are modeled as a regression-mean determined by climate and …

The Lorenz Energy Cycle of the Global Atmosphere during the past 35 Years (1979-2013)
… which are mainly due to the increasing storm activities over the Southern Ocean storm track areas. At the same time, a negative trend is seen in the mean available potential energy (P_M) especially around the North Pole near the surface, which is probably related to the inhomogeneous …

A numerical study for the interdecadal variation in the northern-hemisphere winter circulation
… field, the cyclone activity over the midlatitude storm track region is affected by the variability of the north-south wind shear which is induced by the equatorward expansion of the circumpolar vortex;It is further demonstrated by linearized model simulations that (1) the tropical heating …

Temporal and Spatial Patterns in Optical Properties of Colored Dissolved Organic Matter on Florida’s Gulf Coast: Shelf to Stream to Aquifer
… closely with a number of factors prior to a storm's passing such as the presence of persistant blooms, rainfall and discharge. Additionally, storm track and wind direction were found to play a significant role in CDOM signatures. A study of ten riversheds located between the Mississippi / …

Modeling the role of soil moisture in North American summer climate
… large-scale dynamics, which tends to induce a storm track shift that enhances the soil moisture-rainfall feedback. Depending on the region, soil moisture perturbations not only impact the local climate, but also remote climates.

Statistical models for extreme weather events
… months, which typically take the form of windstorms or flooding. The storm Desmond brought strong winds and heavy rain to Ireland, northern England and Scotland in December 2015, resulting in an estimated $500 million worth of damage and extensive flooding, particularly in the region of …

High-resolution environmental change in the late Jurassic Kimmeridge clay formation
… These pulses are interpreted as the result of storms causing re-suspension and transportation of organic material, clays and nutrients from the proximal shelf into the distal basin. These storm events occur at the beginning and end of the coccolith limestones and thus, are suggested to have …
