An Empirical Examination Of The Environmental Variability That Impacted Supercell Evolution, Longevity, And Severe Weather Production On 22 May 2019 In Oklahoma, Kyle D. Pittman

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Mesoscale environmental heterogeneity can have significant impacts on thunderstorm organization, evolution, longevity, and severe weather production. This study examines the 22 May 2019 thunderstorm event in Oklahoma, where a relatively broad area of strong instability and vertical wind shear existed along a synoptic boundary and in the open warm sector that would seem to support long-lived supercells and tornadoes. There were two particularly dangerous situation (PDS) tornado watches issued during the event, but few severe reports and no tornadoes formed in the watch that covered the southwestern portion of the state. Several tornadic supercells and many more severe reports occurred …

Data For Paper "Agile Adaptive Radar Sampling Of Fast-Evolving Atmospheric Phenomena Guided By Satellite Imagery And Surface Cameras", Mariko Oue, Pavlos Kollias, Edward Luke, Katia Lamer

SoMAS Research Data

The data include:

• Stony Brook University phased array radar (SKYLER) data collected on August 21, 2019 and September 2, 2019.
• Stony Brook University Ka-band scanning polarimetric cloud radar (KASPR) data collected on August 21, 2019, August 25, 2019, and September 2, 2019.

Those data were used in the paper "Agile adaptive radar sampling of fast-evolving atmospheric phenomena guided by satellite imagery and surface cameras" submitted to Geophysical Research Letters.

A New York State Mesonet Based Analysis Of Squall Line Cold Pool Strength And Uses For Short Term Forecasting, Daniel William Reese

Legacy Theses & Dissertations (2009 - 2024)

The recently finished New York State Mesonet (NYSM) has a network of 126 standard surface sites and 17 vertical profiler sites across the state. This high density network allows for a wide range of potential uses in research and operational forecasting. One such use is in the area of severe thunderstorm forecasting, where mesoscale and storm scale features can become highly important. This thesis examines three case studies, events from 2017-2018 that produced long-lived, high impact squall lines which moved across the state. As the squall line’s cold pool has long been recognized to play a critical role in squall …
