Verification And Analysis Of Impact-Based Tornado Warnings In The Central Region Of The National Weather Service, Holly B. Obermeier 2014 University of Nebraska - Lincoln

Verification And Analysis Of Impact-Based Tornado Warnings In The Central Region Of The National Weather Service, Holly B. Obermeier

Dissertations & Theses in Earth and Atmospheric Sciences

Tornado warnings are one of the most critical products issued by the National Weather Service (NWS), and favorable verification statistics are desirable. The 2011 NWS statistics for traditional tornado warnings indicate that the probability of detection (POD) is 70%, while the false alarm rate (FAR) is 76%. The recent Joplin, Missouri EF5 tornado event on 22 May 2011, which resulted in massive devastation and loss of life, prompted the NWS to re-evaluate the current tornado warning format. After the Joplin, MO event, the Central Region of the NWS implemented the impact-based tornado warning (IBTW) experiment in 2013. IBTWs consist of ...


A Geospatial Approach For Prioritizing Wind Farm Development In Northeast Nebraska, Usa, Adam Miller, Ruopu Li 2014 University of Nebraska - Lincoln

A Geospatial Approach For Prioritizing Wind Farm Development In Northeast Nebraska, Usa, Adam Miller, Ruopu Li

Papers in Natural Resources

Being cleaner and climate friendly, wind energy has been increasingly utilized to meet the ever-growing global energy demands. In the State of Nebraska, USA, a wide gap exists between wind resource and actual energy production, and it is imperative to expand the wind energy development. Because of the formidable costs associated with wind energy development, the locations for new wind turbines need to be carefully selected to provide the greatest benefit for a given investment. Geographic Information Systems (GIS) have been widely used to identify the suitable wind farm locations. In this study, a GIS-based multi-criteria approach was developed to ...

The Mann-Kendall test and the Sen’s slope test were applied to investigate temporal trends. Monthly wind directions were examined against monthly precipitation patterns. Main findings from the study include the following: (1) Annual precipitation significantly increased in the northern part of the study area during 1950-2006, whereas extreme precipitation showed virtually no trends; (2 ...


Midlatitude Mesospheric Temperature Anomalies During Major Ssw Events As Observed With Rayleigh-Scatter Lidar, Leda Sox, Vincent B. Wickwar, Chad Fish, Josh P. Herron 2014 Utah State University

Midlatitude Mesospheric Temperature Anomalies During Major Ssw Events As Observed With Rayleigh-Scatter Lidar, Leda Sox, Vincent B. Wickwar, Chad Fish, Josh P. Herron

Leda Sox

While the mesospheric temperature anomalies associated with Sudden Stratospheric Warmings (SSWs) have been observed extensively in the polar regions, observations of these anomalies at midlatitudes are sparse. The original Rayleigh-scatter lidar that operated at the Atmospheric Lidar Observatory (ALO; 41.7°N, 111.8°W) in the Center for Atmospheric and Space Sciences (CASS) on the campus of Utah State University (USU) collected a very dense set of temperature data for 11 years, from 1993 through 2004. The temperatures derived from these data extended over the mesosphere, from 45 to 90 km. This work focuses on the extensive Rayleigh lidar ...

Climate Planning In Politically Conservative Cities: A Case Study Of Seven Climate Action Plans, Coleman Moore Frick 2014 California Polytechnic State University

Climate Planning In Politically Conservative Cities: A Case Study Of Seven Climate Action Plans, Coleman Moore Frick

Master's Theses and Project Reports

Current research indicates that the potential risks associated with human-induced climate change are likely to increase in frequency and intensity. Although there have been several attempts, no effective international treaty or policy has been enacted by the United States with the purpose of combating this global issue. In the past decade, local climate action plans (CAPs) have emerged as a planning solution designed to reduce greenhouse emissions (GHGs). Previous studies have examined CAP attributes, but no research has focused solely on climate planning in politically conservative jurisdictions. This research finds that of 245 CAPs completed to date nationally, approximately 90 ...

In order to determine the characteristics of the midlatitude mesospheric temperatures during ...


Evolution Of Land Surface Air Temperature Trend, Fei Ji, Zhaohua Wu, Jianping Huang, E.P. Chassignet 2014 The Florida State University

Evolution Of Land Surface Air Temperature Trend, Fei Ji, Zhaohua Wu, Jianping Huang, E.P. Chassignet

COAPS Publications

The global climate has been experiencing significant warming at an unprecedented pace in the past century1, 2. This warming is spatially and temporally non-uniform, and one needs to understand its evolution in order to better evaluate its potential societal and economic impact. In this paper, the evolution of global land surface temperature trend in the last century is diagnosed using the spatial–temporally multidimensional ensemble empirical mode decomposition method3. We find that the noticeable warming (>0.5 K) started sporadically over the global land and accelerated until around 1980. Both the warming rate and spatial structure have changed little since ...

The survey consisted of questions regarding what the residents expected concerning the threat of Hurricane Sandy, whether it matched what they experienced, where they got their information and how they made their decision to evacuate or not. The results from the survey were statistically ...


Improving Spectrophotometric Carbon System Measurements, Mark Patsavas 2014 University of South Florida

Improving Spectrophotometric Carbon System Measurements, Mark Patsavas

Graduate School Theses and Dissertations

This work provides improved procedures for spectrophotometric carbon system measurements. Indicator dyes used for routine spectrophotometric pH measurements in seawater suffer from impurity issues, which introduce vendor-specific systematic errors in pH determinations. The magnitude of these errors for several vendors was investigated for meta Cresol Purple (mCP) and Cresol Red (CR). Flash chromatography procedures were developed to obtain purified mCP and CR on a bulk scale in order to supply the oceanographic research community with the indicators. Easy access to the purified indicators ensures global intercomparability of spectrophotometric pH determinations.

Internal consistency of marine inorganic carbon system measurements was studied ...


Baseline Studies Of Selected Polybrominated Diphenyl Ethers In The Air Of The Nandamojo Watershed, Costa Rica, Mary Sophia Geesey 2014 University of South Florida

Baseline Studies Of Selected Polybrominated Diphenyl Ethers In The Air Of The Nandamojo Watershed, Costa Rica, Mary Sophia Geesey

Graduate School Theses and Dissertations

Polybrominated diphenyl ethers (PBDEs) have been used as flame retardants in a number of common household and commercial products around the world. PBDEs enter the environment in a variety of ways, such as through emissions, leaching from end-of-life electronics in landfills, and incineration. While many countries have phased out the manufacturing of penta-, octa-, and deca-PBDEs or have banned the manufacture and use of these congeners altogether, these persistent organic pollutants (POPs) continue to be detected in humans and the environment.

This study investigates spatial and temporal variations of selected PBDEs in the air of the Nandamojo watershed area in ...

NOAA archive data was retrieved to create a database that was used to categorize text files of hail days. The text files were entered into the National Oceanic and Atmospheric Administration Earth System Research Laboratory website to create National Centers for Environmental Prediction/National Center for ...


Influence Of Diet On Element Incorporation In The Shells Of Two Bivalve Molluscs: Argopecten Irradians Concentricus And Mercenaria Mercenaria, William Noland Elsaesser 2014 University of South Florida

Influence Of Diet On Element Incorporation In The Shells Of Two Bivalve Molluscs: Argopecten Irradians Concentricus And Mercenaria Mercenaria, William Noland Elsaesser

Graduate School Theses and Dissertations

Recently, biogenic carbonates have received much attention as potential proxies of environmental change; however, a major pathway of elemental incorporation is often overlooked when making interpretations or designing experiments. This research experimentally examines the influence of diet on elemental composition in juvenile shells of the bay scallop, Argopecten irradians concentricus, and the northern quahog, Mercenaria mercenaria.

Exploratory trials were conducted using Argopecten irradians concentricus juveniles fed different algal diets: Isochrysis, Chaetoceros, Pavlova, Tetraselmis, or a mix of all four in a 2:1:2:2 ratio. No differences between the left and right valves were revealed, thus, subsequent analysis of ...
