Developing Tornado Climatology In The Southern Great Plains Per Phases Of Prominent Oceanic Oscillations, Nicholas M. Fillo
Developing Tornado Climatology In The Southern Great Plains Per Phases Of Prominent Oceanic Oscillations, Nicholas M. Fillo
Geography and the Environment: Graduate Student Capstones
Meteorologists are continually working toward a greater understanding of which atmospheric environments are most conducive for tornado development. This Capstone project analyzed tornado occurrences across Texas, Oklahoma, Arkansas and Louisiana during the period 1950 through 2009 to determine if any correlation exists between the location and frequency of tornado activity and the phases of the El Nino-Southern Oscillation, the Atlantic Multidecadal Oscillation and the Pacific Decadal Oscillation. While it was determined that no phase of any of the oscillations studied was significantly more dominant over the other(s) concerning frequency, this project does identify some spatial shifts in tornado activity depending …

Sudden Oak Death (SOD), caused by the pathogenic water mold Phytophthora ramorum, has killed hundreds of thousands of oak trees in the California coastal regions, with redwood-tanoak forests being hit the hardest (Shoemaker et al., 2007). The term “sudden oak death” is used to describe the disease, because of how rapidly the pathogen has killed otherwise healthy tanoaks, virtually in a matter of weeks (COMTF 2010). SOD was first reported in California in 1994 and is believed to have originated from infected nursery or ornamental plants, but the source has never been identified (Mascheretti et al. 2008).
