The El Niño Southern Oscillation (ENSO) consists of a linkage between changes in sea-surface temperatures and atmospheric pressure across the Tropical Pacific.

The El Niño Southern Oscillation (ENSO) consists of a linkage between changes in sea-surface temperatures and atmospheric pressure across the Tropical Pacific. ENSO encompasses three phases: neutral events, warm/El Niño events in which sea-surface temperatures are warmer-than-normal and the pressure gradient decreases across the Equatorial Pacific, and cold/La Niña events in which Tropical Pacific sea-surface temperatures are cooler-than-normal and the pressure gradient increases. Previous studies have determined a connection between variations in ENSO phase and weather patterns across the globe, focusing particularly on surface temperature and precipitation patterns in the United States. However, little research exists that attempts to link changes in ENSO phase with severe weather in Arizona. Therefore, in this study, I analyzed how variations in ENSO phase affect the frequency, intensity, and spatial distribution of four types of severe weather from 1959 to 2016 in Arizona, including a) tornado events, b) severe thunderstorm wind events, c) hail events, and d) heavy rain and flash flood events. I collected data on the Oceanic Niño Index (ONI), a measure of ENSO, as well as storm reports for each severe weather phenomenon dating back to 1959. Then, I analyzed the frequency of each Arizona severe weather event type within each of the twelve annual months and over the entire study period. I also analyzed mean intensity values (Fujita/Enhanced Fujita Scale rating, path width, and path length for tornadoes; hail diameter in millimeters for hail; and wind gust speed for severe thunderstorm wind events) for each severe weather phenomenon, excluding the heavy rain and flash flood events. Finally, I used the Mean Center and Directional Distribution tools in ArcGIS to determine variations in the spatial distribution and mean centers between each ENSO phase for each severe weather event type. I found that ENSO phase, particularly La Niña, does impact the frequency and intensity of tornadoes, hail, thunderstorm wind, and heavy rain/flash flood events in Arizona. However, it appears that ENSO does not affect the spatial distribution of these Arizona severe weather phenomena. These findings attempt to fill in the gap in the literature and could help meteorologists better forecast changes in Arizona severe weather, in turn allowing Arizonans to better prepare for and mitigate the effects of severe weather across the state.

News outlets frequently portray people with disabilities as either helpless victims or objects of motivation. Portrayal of people with disabilities has improved over the years, but there is still room to grow. News outlets tend to make disability the center of the story. A story about a disabled person is primarily about their disability, with their other accomplishments framed by it.

As one example of the victimhood narrative, ABC News used to run a special called My Extreme Affliction as part of 20/20 until 2012. As the name implies, the specials covered people with disabilities, specifically extreme versions. One 2008 episode on Tourette’s syndrome described Tourette’s like it was some sort of demonic possession. The narrator talked about children who were “prisoners in their own bodies” and a family that was at risk of being “torn apart by Tourette’s.” I have Tourette’s syndrome myself, which made ABC’s special especially uncomfortable to watch. When not wringing their metaphorical hands over the “victims” of disability, many news outlets fall into the “supercrip” narrative. They refer to people as “heroes” who “overcome” their disabilities to achieve something that ranges from impressive to utterly mundane. The main emphasis is on the disability rather than the person who has it. These articles then exploit that disability to make readers feel good. As a person with a disability, I am aware that it impacts my life, but it is not the center of my life. The tics from my Tourette’s syndrome made it difficult to speak to people when I was younger, but even then they did not rule me.

Disability coverage, however, is still incredibly important for promoting acceptance and giving people with disabilities a voice. A little over a fifth of adults in the United States have a disability (CDC: 53 million adults in the US live with a disability), so poor coverage means marginalizing or even excluding a large amount of people. Journalists should try to reach their entire audience. The news helps shape public opinion with the stories it features. Therefore, it should provide visibility for people with disabilities in order to increase acceptance. This is a matter of civil rights. People with disabilities deserve fair and accurate representation.

My personal experience with ABC’s Tourette’s special leads me to believe that the media, especially the news, needs to be more responsible in their reporting. Even the name “My Extreme Affliction” paints a poor picture of what to expect. A show that focuses on sensationalist portrayals in pursuit of views further ostracizes people with disabilities. The emphasis should be on a person and not their condition. The National Center for Disability Journalism tells reporters to “Focus on the person you are interviewing, not the disability” (Tips for interviewing people with disabilities). This people-first approach is the way to improve disability coverage: Treat people with disabilities with the same respect as any other minority group.

High levels of surface ozone pollution have been shown to have adverse effects on human health and our environment. For at least the past decade, ozone concentrations in Phoenix, Arizona have been above the federal health standard, set in place by the Environmental Protection Agency. It is crucial that all factors contributing to rising tropospheric ozone levels within the Phoenix metropolitan area are analyzed to better understand this risk for future mitigation efforts. Consequently, the primary objective of this study is specifically to examine meteorological factors' influence on Phoenix’s ground level ozone by comparing days of ozone exceedances with ozone non-exceedances days over the course of 2010-2020. To carry out this research, various weather conditions for both exceedance and non-exceedance ozone days were studied using unpaired Student’s t-tests and Pearson product-moment correlation tests. The results of this study suggest that the most significant factors that are associated with the occurrence of surface ozone exceedances in Phoenix are wind speed and temperature, whereas the least significant variables are wind direction and sky conditions. This indicates that more stable synoptic conditions in which skies are clearer, allowing for higher temperatures and more stagnant air movement, are ideal for ozone production leading to an ozone exceedance. The results from this honors thesis will be useful as it will aid in greater understanding of the relationship between Phoenix’s surface ozone and weather, aiding future ozone forecasting.
