  • Open Tobin Dissertation V2.Pdf
    The Pennsylvania State University The Graduate School A MULTI-FACETED VIEW OF WINTER PRECIPITATION: SOCIETAL IMPACTS, POLARIMETRIC RADAR DETECTION, AND MICROPHYSICAL MODELING OF TRANSITIONAL WINTER PRECIPITATION A Dissertation in Meteorology and Atmospheric Science by Dana Marie Tobin 2020 Dana Marie Tobin Submitted in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy December 2020 ii The dissertation of Dana Marie Tobin was reviewed and approved by the following: Matthew R. Kumjian Associate Professor of Meteorology Dissertation Advisor Chair of Committee Eugene E. Clothiaux Professor of Meteorology Jerry Y. Harrington Professor of Meteorology Vikash V. Gayah Associate Professor of Civil and Environmental Engineering David J. Stensrud Professor of Meteorology Head of the Department iii ABSTRACT There remain several unanswered questions related to transitional winter precipitation, ranging from the impacts that it has on society to what microphysical processes are involved with its formation. With an improved understanding of the formation and impacts of transitional winter precipitation types, it is possible to reduce or minimize their adverse societal impacts in the future by improving their detection and forecasting. Precipitation is known to have an adverse effect on motor vehicle transportation, but no study has quantified the effects of ice pellets or freezing precipitation. An investigation of the number of vehicle-related fatalities during each precipitation type reveals a bias in the number of transitional-winter-precipitation type categories such that the fatality data cannot be used as-is to quantify the impacts of precipitation on vehicle fatalities with certainty. Matching traffic crash data to nearby precipitation-type reports provides an avenue to identify periods of precipitation during which a crash occurred.

This change amends practices and procedures in Surface Weather Observing and also defines the FAA Weather Observation Quality Control Program. 2. Audience. This order applies to all FAA and FAA-contract personnel, Limited Aviation Weather Reporting Stations (LAWRS) personnel, Non-Federal Observation (NF-OBS) Program personnel, as well as United States Coast Guard (USCG) personnel, as a component ofthe Department ofHomeland Security and engaged in taking and reporting aviation surface observations. 3. Where I can find this order. This order is available on the FAA Web site at http://faa.gov/air traffic/publications and on the MyFAA employee website at http://employees.faa.gov/tools resources/orders notices/. 4. Explanation of Changes. This change adds references to the new JO 7210.77, Non­ Federal Weather Observation Program Operation and Administration order and removes the old NF-OBS program from Appendix B. Backup procedures for manual and digital ATIS locations are prescribed. The FAA is now the certification authority for all FAA sponsored aviation weather observers. Notification procedures for the National Enterprise Management Center (NEMC) are added. Appendix B, Continuity of Service is added.
