PERCEPTIONS OF VULNERABILITY TO SEVERE’ WEATHER IN PANGNIRTUNG, NUNAVUT
… The local government characterized the event as 'severe’, however several residents pointed out the effects to the land and impacts to the community were at best exciting, and at worst, inconvenient. This thesis explores firstly, how the concept of ‘severe’ weather is constructed by social groups …

The utility of total lightning observations in severe weather forecasting
A key aspect of short term weather forecasting is the ability to provide the public with adequate lead time in the event of severe weather. During severe weather events, it is vital that real time information such as radar data and spotter reports are available to aid National Weather Service (NWS) …

How College Campuses Are Using Social Media During Severe Weather Events
… college campuses are using social media during severe weather events. This topic surfaced after a tornado devastated Moore, Oklahoma in May 2013 and those displaced flocked to the University of Oklahoma campus after a post made on Twitter went viral prior to an official message being sent out by …

Subseasonal to seasonal prediction and predictability of extreme and severe weather
… 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 activity. Successful prediction of …

The use of conditional and potential instability axes for severe weather forceasting
In this thesis, we used an innovative approach to severe weather forecasting using traditional forecast parameters. The maximum theta-e (potential instability) in the lowest 300 mb and the deep-layer lapse rate (conditional instability) fields are two commonly used forecast parameters for severe …

An Analysis of SeaWinds Simultaneous Wind/Rain Retrieval in Severe Weather Events
Scatterometers, such as SeaWinds, can provide wide coverage of ocean surface winds. They estimate near-surface wind vectors by relating measured radar backscatter to a geophysical model function. However, SeaWinds measurements are also sensitive to rain, and conventional wind retrieval degrades in …

Estimating midlevel updraft characteristics and severe weather intensity through the lens of overshooting tops
… OTA was also used to estimate the intensity of severe convective weather phenomena, expanding upon a previous study that was focused solely on tornado intensity. Reports of severe hail, severe straight-line winds, and tornadoes were paired with their respective OT events, and then the peak …

Integrating social media and rainfall data to understand the impacts of severe weather in Argentina
… USD in damages. Furthermore, the national weather service in Argentina has a history of operational issues, the most glaring of which is that a single office in Buenos Aires is responsible for forecasting for the entire country. Consequently, there is a large disconnect between the weather …

The Association of Strong Near-Surface Wind Shear Profiles with Enhanced Probabilities of Significant Severe Weather and Tornado Events.
… occurrence of the sickle-shape was related to severe weather documented within spatial and temporal proximity of the sounding site. Over the 10-year dataset, the sickle-shape was found to occur at most 4% of the time. It was also found that the sickle-shape occurs less than 0.5% of the time in …

Do hurricanes and other severe weather events affect catch per unit effort of reef-fish in the Florida Keys?
Severe weather events frequently affect important marine fish stocks and fisheries along the United States Atlantic and Gulf of Mexico coasts. However, the effects of these events on fish and fisheries are not well understood. The availability of self-reported data from two fisheries in a region …

Community Warning Systems: Factors influencing citizen decision-making
… of a community regarding the potential of severe weather is essential for the safety and well-being of those affected. Such alerts/warnings must be tailored to accommodate all facets of the diverse population within communities. Essential to this is the construction and<br/>conveyance of a …

Storm Spotting and Amateur Radio: a Field Guide for Volunteer Storm Spotters
… have played a critical part in relaying weather information since the middle 19th century. The effort of these volunteers has helped safeguard life and property when severe weather threatens. For almost 100 years Amateur Radio operators have played a critical part in severe weather …

Climate change and hazardous convective weather in the United States: Insights from high-resolution dynamical downscaling
… conditions favorable for hazardous convective weather (HCW) may increase in frequency in the future due to anthropogenic climate change. However, this storm environment-based approach is undoubtedly limited by the assumption that convective-scale phenomena will be realized within these …

Atmospheric Rivers Effects on Severe Convective Storm Environments from 1979 to 2023
… role of Atmospheric Rivers (ARs) in modulating Severe Convective Storm Environments (SCSEs) in the Mid-South United States from 1979 to 2023, leveraging ECMWF Reanalysis v5 reanalysis and the practically perfect hindcast dataset. AR detection was performed using seven different Atmospheric River …

Assessing the relationship between high lightning events and storm mode in Northern and Central Alabama
… underestimated by the public and excluded from severe weather watches and warnings used by the National Weather Service. Previous studies have analyzed the relationship of lightning and storm intensity in relation to severe weather, but none have analyzed this relationship across all storm modes …
