Effect Of Aerosol Distributions On Precipitation Patterns Needed For A Rapid Ice Age, 2018 Cedarville University
Effect Of Aerosol Distributions On Precipitation Patterns Needed For A Rapid Ice Age, Steven M. Gollmer
The Proceedings of the International Conference on Creationism
Introduced in the Genesis Flood by Whitcomb and Morris (1961) and fleshed out by Oard (1979) a model for an ice age in the wake of the Genesis flood was used to explain the evidence of glaciation in Canada and the United States without resorting to eons of time. It was proposed that this rapid ice age was the consequence of post flood warm oceans, barren land and volcanic aerosols. The impact of warm oceans was simulated by Vardiman (1998) and Gollmer (2013) using climate models. Although warm oceans increase precipitation in the Arctic, global surface temperatures become unbearably hot ...

Discrimination of the type of air mass along mountain slopes can be a challenge and is not commonly performed, but is critical for identifying factors responsible for influencing montane weather, climate, and air quality. A field campaign to measure air mass type and transitions on the summit of Mount Washington, New Hampshire, USA was performed on 19 August 2016. Meteorological observations were taken at the summit and at several sites along the east and west slopes. Ozone concentrations were measured at the summit and on the valley floor. Additionally, water vapor stable isotopes were measured from a truck that drove ...
Mechanisms Of Abrupt Extreme Precipitation Change Over The Northeastern United States, 2018 Dartmouth College
Mechanisms Of Abrupt Extreme Precipitation Change Over The Northeastern United States, Huanping Huang, Jonathan M. Winter, Erich C. Osterberg
Open Dartmouth: Faculty Open Access Articles
In 1996, the northeastern United States experienced an abrupt increase in extreme precipitation, but the causal mechanisms driving this increase remain poorly understood. We find that 89% of the 1996–2016 increase relative to 1979–1995 is explained by only 273 unique extreme events affecting >5 stations and occurring in the months of February, March, June, July, September, and October. We use daily weather maps to classify the 273 extreme precipitation events by meteorological cause (tropical cyclones, fronts, and extratropical cyclones) and use reanalysis data to determine large‐scale changes in the atmosphere and ocean associated with increased extreme precipitation ...
Controls On Deuterium Excess Across Asia, 2018 Portland State University
Controls On Deuterium Excess Across Asia, John Bershaw
Geology Faculty Publications and Presentations
Deuterium excess (d-excess) is a second-order stable isotope parameter measured in meteoric water to understand both the source of precipitation and the evolution of moisture during transport. However, the interpretation of d-excess patterns in precipitation is often ambiguous, as changes in moisture source and processes during vapor transport both affect d-excess in non-unique ways. This is particularly true in Asia where continental moisture travels a long distance across diverse environments from unique moisture sources before falling as precipitation. Here, I analyzed published d-excess records from meteoric water throughout Asia to better characterize what influences d-excess values. I conclude that, (1 ...

Aerosol And Meteorological Parameters Associated With The Intense Dust Event Of 15 April 2015 Over Beijing, China, Sheng Zheng, Ramesh P. Singh
Mathematics, Physics, and Computer Science Faculty Articles and Research
The northeastern parts of China, including Beijing city, the capital of China, were hit by an intense dust storm on 15 April 2015. The present paper discusses aerosol and meteorological parameters associated with this dust storm event. The back trajectory clearly shows that the dust originated from Inner Mongolia, the border of China, and Mongolia regions. Pronounced changes in aerosol and meteorological parameters along the dust track were observed. High aerosol optical depth (AOD) with low Ångström exponent (AE) are characteristics of coarse-mode dominated dust particles in the wavelength range 440–870 nm during the dusty day. During dust storm ...
Description And Mechanisms Of The Mid-Year Upwelling In The Southern Caribbean Sea From Remote Sensing And Local Data, 2018 Old Dominion University
Description And Mechanisms Of The Mid-Year Upwelling In The Southern Caribbean Sea From Remote Sensing And Local Data, Digna T. Rueda-Roa, Tal Ezer, Frank E. Muller-Karger
The southern Caribbean Sea experiences strong coastal upwelling between December and April due to the seasonal strengthening of the trade winds. A second upwelling was recently detected in the southeastern Caribbean during June-August, when local coastal wind intensities weaken. Using synoptic satellite measurements and in situ data, this mid-year upwelling was characterized in terms of surface and subsurface temperature structures, and its mechanisms were explored. The mid-year upwelling lasts 6-9 weeks with satellite sea surface temperature (SST) ~1-2°C warmer than the primary upwelling. Three possible upwelling mechanisms were analyzed: cross-shore Ekman transport (csET) due to alongshore winds, wind curl ...
A Diagnostic Metric For Predicting Tropical Cyclone And Mid-Latitude Floods, 2018 Embry-Riddle Aeronautical University
A Diagnostic Metric For Predicting Tropical Cyclone And Mid-Latitude Floods, Jonathon Klepatzki, Shawn M. Milrad
Beyond: Undergraduate Research Journal
This study details a dynamic and thermodynamic metric (i.e., Extreme Flood Index [EFI]) designed to diagnose the frequency and intensity of extreme precipitation events associated with stagnant mid-latitude flow patterns (i.e., Rex blocks). As the global climate warms, rapid Arctic warming may be helping to slow the mid-latitude westerly jet stream, resulting in increased mid-latitude flow stagnation. The combination of long-duration ascent associated with easterly winds and warm moist air increases the severity of extreme precipitation events; as such, the EFI is specifically designed to detect this potent combination of ingredients. In 2013, a Rex block stalled a ...
Large-Scale Regime Transitions And Atmospheric River Landfalls Across Western North America, 2018 M.S. Applied Meteorology
Large-Scale Regime Transitions And Atmospheric River Landfalls Across Western North America, Sam Webber
Recent studies suggest a potential relationship between flow patterns described by the Pacific North American (PNA) teleconnection pattern and landfalling atmospheric rivers (ARs) over western North America. This relationship illustrates an on average positive to negative trend in the PNA in the days leading up to and after a landfalling AR along the California coastline. The goal of this study is to extend prior research by specifically investigating large-scale regime transitions over the Northeast Pacific as described by transitions in the PNA and their relation to AR landfall events. Regime transitions are defined as a change of at least one ...
A Multiscale Analysis Of An Ice Jam Flood On The Pemigewasset River In Central New Hampshire On 26 February 2017, 2018 M.S. Applied Meteorology
A Multiscale Analysis Of An Ice Jam Flood On The Pemigewasset River In Central New Hampshire On 26 February 2017, Matthew Sanders
Ice jams and their floods occur during winter and spring in the northeastern U.S. and can have locally high impacts. A high-impact ice jam flood formed on the Pemigewasset River between Ashland and Plymouth on 26 February 2017. The rain from the cold front combined with precursor above freezing temperatures and a deep ripening snowpack to produce enhanced streamflow, ice break-up, damming, and flooding in Holderness that resulted in dozens of Plymouth State University students losing their vehicles. The first two weeks of February in featured below freezing temperatures and a series of heavy snowfall events in New Hampshire ...
Using Atmospheric O2 And Co2 Measurements To Determine The Stoichiometry Of Photosynthesis And Respiration In A Temperate Forest, Margaret Marie Conley
The O2:CO2 exchange ratio of the terrestrial biosphere (αb) is an important parameter in carbon sink calculations, but its value is not well constrained. We investigate the stoichiometry of O2 and CO2 at Harvard Forest in Petersham, Massachusetts over a span of six years, considering the covariation of O2 and CO2 in forest air during 6-hour periods to determine an average value for the O2:CO2 exchange ratio. This approach provides a way to determine the value of αb averaged across seasonal cycles and species assemblages. Our analysis produces ...
Assessing Effective Rhetoric On Twitter In Relation To Forecast Uncertainty In Hurricane Tracks, 2018 University at Albany, State University of New York
Assessing Effective Rhetoric On Twitter In Relation To Forecast Uncertainty In Hurricane Tracks, Erin K. Lynch
Atmospheric & Environmental Sciences
A forecast is only as good as the way it is communicated. As the National Weather Service (NWS) transitions to an Impact-Based Communication style, the new public forecasts discuss how to effectively prepare and protect oneself from harm in the face of severe and significant weather. After severe events, meteorologists need to take the time to analyze the language and style of the rhetoric to assess how effective it was at getting people in harm’s way to take protective actions. It is even more important to understand how information was communicated when there is large uncertainty in the forecast ...
Differences Between High Shear / Low Cape Environments In The Northeast Us Favoring Straight-Line Damaging Winds Versus Tornadoes, 2018 University at Albany, State University of New York
Differences Between High Shear / Low Cape Environments In The Northeast Us Favoring Straight-Line Damaging Winds Versus Tornadoes, Michael E. Main, Ross A. Lazear, Lance F. Bosart
Atmospheric & Environmental Sciences
High shear / low CAPE (HSLC) environments are common in the Northeast US and can occur at any time of year. Severe weather in HSLC environments is notoriously hard to predict, often catching both forecasters and the general public off-guard. The goal of this project is to help forecasters to identify HSLC environments favorable for severe weather in the Northeast US, and to discriminate between HSLC environments that are supportive of tornadoes versus those that favor straight-line damaging winds (SDW). A 10-year HSLC severe weather environmental climatology was created for the Northeast US (New England, New York, New Jersey, Pennsylvania). This ...
Understanding Microphysical Processes Occurring In Lake-Effect Snowbands Using Quasi-Vertical Profiles Of Wsr-88d Parameters, 2018 University at Albany, State University of New York
Understanding Microphysical Processes Occurring In Lake-Effect Snowbands Using Quasi-Vertical Profiles Of Wsr-88d Parameters, Marquette Rocque
Atmospheric & Environmental Sciences
Knowing the composition and microphysical processes that occur in lake-effect precipitation systems is important in making sure models capture these processes accurately, and could aid forecasters in predicting snow totals and snow water equivalents. Many studies have shown that processes such as riming and dendritic growth can be seen in dual-polarization radar data through parameters such as equivalent radar reflectivity factor, differential reflectivity (ZDR), correlation coefficient, and differential phase. This research examines WSR-88D data from the KTYX (Montague, NY) radar located on the Tug Hill Plateau for several long-lake-axis-parallel lake-effect systems from the Ontario Winter Lake-effect Systems (OWLeS) field campaign ...

Statistical Analysis And Comparison Of Optical Classification Of Atmospheric Aerosol Lidar Data, 2018 Old Dominion University
Statistical Analysis And Comparison Of Optical Classification Of Atmospheric Aerosol Lidar Data, Kwasi Gyening Afrifa
Electrical & Computer Engineering Projects for D. Eng. Degree
This dissertation presents a new study for the analysis and classification of atmospheric aerosols in remote sensing LIDAR data. Information on particle size and associated properties are extracted from these remote sensing atmospheric data which are collected by a ground-based LIDAR system. This study first considers optical LIDAR parameter-based classification methods for clustering and classification of different types of harmful aerosol particles in the atmosphere. Since accurate methods for aerosol prediction behaviors are based upon observed data, computational approaches must overcome design limitations, and also consider appropriate calibration and estimation accuracy. Consequently, two statistical methods based on generalized linear models ...
Atmospheric Radiation And Tgfs: Unexplained Radiation In Our Skies, 2018 Harding University
Atmospheric Radiation And Tgfs: Unexplained Radiation In Our Skies, Adrian Gallegos
Honors College Research
There is a significant correlation between atmospheric electrification via thunderstorms and the occurrence of large emissions of x-ray and gamma ray radiation known as Terrestrial Gamma Ray Flashes (TGFs). Some physical phenomenon may be explained by either the RREA or Thermal Runaway models, but the scientific community as a whole is still largely at work on the theoretical frameworks.
Multidecadal Variability In The Subseasonal Peak Of Low-Level Convergence Over The Pacific Warm Pool, 2018 Utah State University
Multidecadal Variability In The Subseasonal Peak Of Low-Level Convergence Over The Pacific Warm Pool, Yen-Heng Lin, Shih-Yu (Simon) Wang
Plants, Soils, and Climate Faculty Publications
In the Western North Pacific (WNP), the atmospheric low-level convergence is one of the main factors that influences the genesis of tropical cyclones (TC). It has been observed that the timing of the seasonal maxima in the low-level convergence and TC genesis has shifted since the mid-1990s from mid-August to late-July, with this shift having also affected the number of TC. A multidecadal frequency of 20 years was revealed in the timing variation of the tropical intraseasonal oscillation (ISO) in the Western Pacific, in which a weak WNP low-level convergence in spring may trigger an advanced ISO phase in summer ...
Construction Of A Pen-Scale Methane Collection System And Dietary Strategies For Methane Mitigation From Growing And Finishing Cattle, 2018 University of Nebraska - Lincoln
Construction Of A Pen-Scale Methane Collection System And Dietary Strategies For Methane Mitigation From Growing And Finishing Cattle, Thomas Winders
Theses and Dissertations in Animal Science
Methane production from ruminants has been researched for many years because it has a global warming potential 25x that of carbon dioxide, meaning that mitigating smaller amounts of methane can have a large environmental impact. Research has focused on individual animal methane measurements, but the literature lack in industry-scale measurements. For that reason, the methane barn was built to evaluate dietary strategies on pens of cattle rather than on individual animals. In order to test the methane barn capabilities, an experiment designed to produce differences in methane production was conducted. Cattle received the same growing diet, at either ad-libitum access ...
