Exploring methods to extract vertical motions in winter storms
Methods of retrieving vertical motions in wintertime cyclones are tested for the 915 MHz profiler, a profiling radar on the University of Alabama-Huntsville Mobile Integrated Profiling System, used during several winter cyclones observed during the Profiling of Winter Storms (PLOWS) project. First, …

Bottom boundary layer physics and sediment transport along a transgressive sand body, Ship Shoal, south-central Louisiana: implications for fluvial sediments and winter storms
… dynamics, in concert with fluvial sediments and winter storms, influenced in unique ecosystems, and likely in future potential sand mining. This dissertation addresses such the morphodynamics and sedimentary processes and their implications for the mining from the shoal using field measurements …

The Numerical Simulation of Orographic Storms (Wales, Seeder-Feeder Mechanism, Bergeron)
Recent observational studies of winter storms over the Glamorgan Hills of south Wales (Browning et al., 1974, and Hill et al., 1981) have confirmed the importance of the seeder-feeder mechanism of orographic precipitation enhancement, proposed by Bergeron (1965). However, the latter study also …

Investigation of the comma-head stability structure of wintertime mid-latitude cyclones using high-resolution observations
The Profiling of Winter Storms (PLOWS) field campaign sampled twenty-four winter cyclones over the course of the 2008-2009 and 2009-2010 winter seasons. The goal of this field campaign was to investigate the distribution of instability that leads to precipitation substructures found in the …

Sources and supply of kelp detritus : quantifying mechanisms of production
… region strongly influenced by oceanic swell and winter storms. The study comprised of four major components: the impact of kelp morphology on the drag forces acting on kelp thalli; investigation of wound patterns in kelp tissue and the biomechanical implications for kelp detritus production; the …

A Machine-Learning Based Approach to Predicting Waterborne Disease Outbreaks Caused by Hurricanes
… tropical cyclones including hurricanes and winter storms worldwide. Waterborne diseases, resulting from flood-related impacts, affect public health and are of major concern for society. Previous research studies have highlighted a statistically significant linear correlation between …

Estuarine Dynamics as a Function of Barrier Island Transgression and Wetland Loss: Understanding the Transport and Exchange Processes
… will further increase. Secondary to hurricanes, winter storms are a primary driver in coastal morphology in this region, and this study shows that wind direction and magnitude, as well as atmospheric pressure change greatly affect estuarine exchange. Significant wetland loss and winter storm …

A recent spatial, temporal, and meteorological climatology of thundersnow across the contiguous United States
A 20-winter climatology was conducted across the contiguous United States apart from Florida using automated weather stations. Results yielded several thousand reports with multiple reports sometimes accounting for one case. Cases were split up into categories based upon the setting in which the …

Humanising policy from ‘Warriors to Guardians’: An evaluation of Coordinated Management and Emergency Response Assemblages in Ireland and the US
… Management Assemblages (IEMA) response to the winter storms of 2015/2016 and the United States Emergency Management Assemblages (USEMA) response to the Boston Marathon Bombing in 2013. Fifty-one semi-structured interviews of key stakeholders and emergency response agents were conducted and …

A comparison of X-band polarization parameters with in-situ microphysical measurements in the comma head of two winter cyclones
… present in that volume. During the Profiling of Winter Storms (PLOWS) field campaign the NSF/NCAR C-130 aircraft, equipped with in-situ microphysical probes, made multiple passes through the comma head of two cyclones as the Mobile Alabama X-band (MAX) dual-polarization radar performed …

Long-Term Ambient Noise Statistics in the Gulf of Mexico
… extremely windy months (summer hurricanes and winter storms). Standard deviation is least in the region 100-200 Hz but increases at higher frequencies, especially during periods of high wind variability (summer hurricanes). Skewness is positive from 25-400 Hz and negative from 630-950 Hz. …

Hydrodynamic Characterisation and Wave Current Interaction around Dunnet Head in the Pentland Firth with Implications for Marine Energy Generation
… from the west, especially during autumn and winter storms. As a result, the Pentland Firth and Orkney Waters region is at the global forefront of developments in both tidal stream and wave power conversion but due to the energetic environment relatively few field measurement studies have been …

Observation of Shelfwater Overrunning the Southern Slope Sea
… events showed that wind stress due to winter storms moved the shelf-slope front and with it shelf water offshore to distances ∼10 to 40 km. The offshore displacement of shelf water also appeared to be related to the onshore veering of the Gulf Stream near Cape Hatteras. This veering of …

Electric charging in the comma-head regions of continental winter cyclones
Lightning in the comma-head region of winter cyclones is a relatively rare phenomenon. The nature of the electric charging in wintertime precipitation bands is unknown. During the ProfiLing Of Winter Storms (PLOWS) project, the surface electric field was measured using an electric field mill (EFM) …

Hydrodynamic Controls on Sedimentology and Geomorphology of Marine-Carbonate Ramps: Insights from a Holocene Analogue, Northern Yucatán Shelf, Mexico
… Persistent trade winds, periodic tropical storms and winter storms generate waves that propagate onto shoreface. This mixed energy, wave-dominated ramp system includes lagoon, barrier island, and upper shoreface geomorphic environments. Extensive shore-parallel sand bodies (beach ridges and …

An East Coast Winter Storm Precipitation Climatology
East Coast Winter Storms (ECWS) can have tremendous impacts throughout the eastern regions of the United States. Forecasting influences from these storms, particularly long range and due to seasonal variations, is extremely challenging. Using a previously compiled climatology of ECWS events, an …
