Nashville-Basin Tornadoes: Using Storm Types To Elucidate The Local Climatology And Forecasting Challenges, Morgan Steckler, Kelsey Ellis Jul 2022

Nashville-Basin Tornadoes: Using Storm Types To Elucidate The Local Climatology And Forecasting Challenges, Morgan Steckler, Kelsey Ellis

Pursuit - The Journal of Undergraduate Research at The University of Tennessee

Early 3 March 2020 was a devastating night for many middle Tennessee residents. A strong EF-3 tornado tore through Nashville at 65 mph, and another EF-4 killed 18 in Baxter and Cookeville alone. Residents of the Southeastern United States are particularly vulnerable to tornadoes. This study aims to better understand local forecasting challenges by looking at the types of storms that produce tornadoes. Storm types, also known as convective modes, divide tornado-producing storms into categories by length, shape, multiplicity, and intensity. Distinguishing storms by these modes allows for a broader understanding of their occurrences and impacts. This study specifically evaluates …


High Wind Alerts: A System Created With Observations From The X-Band Teaching And Research Radar, Lauren Warner Aug 2020

High Wind Alerts: A System Created With Observations From The X-Band Teaching And Research Radar, Lauren Warner

The Journal of Purdue Undergraduate Research

Following the August 13, 2011, Indiana State Fair stage collapse tragedy, caused by a wind gust from an approaching thunderstorm, Purdue University enforced a wind speed restriction of 30 mph (13 m s-1) for tents at outdoor events. During these events, volunteers stand outside with handheld anemometers, measuring and reporting when the wind speeds exceed this limit. In this study, we report testing of a new system to automate high-wind alerts based on observations from a Doppler radar, the X-band Teaching and Research Radar (XTRRA), near Purdue’s campus. XTRRA scans over campus at low elevations approximately every 5 minutes. Using …


A Proposed Taxonomy For General Aviation Pilot Weather Education And Training, John M. Lanicci, Thomas A. Guinn, Jayde M. King, Beth Blickensderfer, Robert Thomas, Yolanda Ortiz Jan 2020

A Proposed Taxonomy For General Aviation Pilot Weather Education And Training, John M. Lanicci, Thomas A. Guinn, Jayde M. King, Beth Blickensderfer, Robert Thomas, Yolanda Ortiz

Journal of Aviation/Aerospace Education & Research

As General Aviation (GA) safety continues to remain a focus of the aviation community, GA pilot weather education and training continues to be an active area of interest within the research community. This study introduces a taxonomy for organizing GA pilot weather education and training materials that was originally conceived as part of the FAA’s Weather Technology In the Cockpit research program. The taxonomy is built upon three main knowledge categories, or tiers:1) Weather Phenomena (which includes hazards); 2) Weather Hazard Products; and 3) Weather Hazard Product Sources and their Application. The concept behind the categorization is to link knowledge …


A Field Guide For Weathering: Embodied Tactics For Collectives Of Two Or More Humans, Jennifer Mae Hamilton, Astrida Neimanis Sep 2018

A Field Guide For Weathering: Embodied Tactics For Collectives Of Two Or More Humans, Jennifer Mae Hamilton, Astrida Neimanis

The Goose

In our inherited meteorological practices and frameworks, weather conditions are managed for us in a range of ways (for example, through architecture, technology, commodity culture, infrastructure, economic rationale). This field guide brings the weather back to the body. A traditional field guide provides tools for the individual sovereign human subject to observe and document nature “over there”. In contrast, through a range of different activities, our field guide not only invites investigation and cataloguing of the field that we also comprise, but also challenges what counts as a noteworthy observation regarding the weather and also climate.


The Tornado That Struck Embry-Riddle Aeronautical University On Christmas Day, 2006: Lessons Learned From A Near-Miss, John M. Lanicci Jan 2016

The Tornado That Struck Embry-Riddle Aeronautical University On Christmas Day, 2006: Lessons Learned From A Near-Miss, John M. Lanicci

Journal of Aviation/Aerospace Education & Research

An F2 tornado that touched down in Daytona Beach on Christmas Day afternoon caused over $50 million of damage to the Embry-Riddle Aeronautical University campus and nearby neighborhoods. The tornado was part of a severe-weather outbreak over Florida, Georgia, and South Carolina that began during the overnight hours of 25 December 2006. Examination of surface and upper-level meteorological charts and vertical soundings on the morning of 25 December showed stability and wind-shear conditions favorable for tornadic thunderstorms over this region. The evolution of the squall line that moved through east-central Florida, and the parent thunderstorm that produced the tornado was …


Characterization And Analysis Of Hailstorms In The Northern Great Plains, Thomas Sando Jan 2008

Characterization And Analysis Of Hailstorms In The Northern Great Plains, Thomas Sando

The Journal of Undergraduate Research

Hail is a meteorological occurrence that appears frequently during spring and summer across the Northern Great Plains. This paper first characterizes patterns associated with reported hail events occurring within a five-state region (North Dakota, Minnesota, South Dakota, Iowa, and Nebraska) from 2000-2006 using records taken from the National Climatic Data Center (NCDC) Severe Storms database. Patterns of interest include the seasonality of hail activity for each state and across the region, observational bias in the reporting of hailstone size, and temporal trends in the number of hail reports across the region and in each state. This paper then explores a …
