India is vulnerable to all kinds of natural hazards associated with land, ocean, biosphere, atmosphere, and snow/glaciers. These natural hazards impact large areas and the population living in the affected regions. India is surrounded by ocean on three sides and is vulnerable to cyclonic activities. Every year cyclones hit the east and west coasts of India, affecting the population living along the coasts and infrastructure and inland areas. The extent of the affected inland areas depends on the intensity of the cyclone. On 12 October 2014, a strong cyclone “Hudhud” hit the east coast of India that caused a ...


Impacts Of Pacific Ssts On Atmospheric Circulations Leading To California Winter Precipitation Variability: A Diagnostic Modeling, Boksoon Myoung, Sang-Wook Yeh, Jinwon Kim, Menas Kafatos 2018 APEC Climate Center

Impacts Of Pacific Ssts On Atmospheric Circulations Leading To California Winter Precipitation Variability: A Diagnostic Modeling, Boksoon Myoung, Sang-Wook Yeh, Jinwon Kim, Menas Kafatos

Mathematics, Physics, and Computer Science Faculty Articles and Research

One of the primary meteorological causes of the winter precipitation deficits and droughts in California (CA) is anomalous developments and maintenance of upper-tropospheric ridges over the northeastern Pacific. In order to understand and find the key factors controlling the winter precipitation variability in CA, the present study examines two dominant atmospheric modes of the 500 hPa geopotential height in the Northern Hemisphere using an Empirical Orthogonal Function (EOF) and their associated large-scale circulation patterns for the last 41 winters (1974/75–2014/15). Explaining 17.5% of variability, the second mode (EOF2) shows strong anti-cyclonic circulations in the North Pacific ...


Pulsed Fiber Optics Lasers As Highly Sensitive Sensors, Hanieh Afkhamiardakani 2018 University of New Mexico

Pulsed Fiber Optics Lasers As Highly Sensitive Sensors, Hanieh Afkhamiardakani

Shared Knowledge Conference

An interferometer or resonator is a device in which optical beams of specific frequencies circulate with minimal losses. These losses are completely compensated by the gain inside a laser resonator. A small perturbation introduced inside the laser can affect its frequency, which in turns becomes a metric of that perturbation. The perturbation is usually caused by an electric or magnetic field, rotation, acceleration, nonlinear index of refraction etc. Tiny changes of optical frequency are monitored by superimposing the laser field and a reference field (from the same laser) on a detector. This technique requires creating a laser in which two ...

A Field Guide For Weathering: Embodied Tactics For Collectives Of Two Or More Humans, Jennifer Mae Hamilton, Astrida Neimanis 2018 University of New England, Armidale

A Field Guide For Weathering: Embodied Tactics For Collectives Of Two Or More Humans, Jennifer Mae Hamilton, Astrida Neimanis

The Goose

In our inherited meteorological practices and frameworks, weather conditions are managed for us in a range of ways (for example, through architecture, technology, commodity culture, infrastructure, economic rationale). This field guide brings the weather back to the body. A traditional field guide provides tools for the individual sovereign human subject to observe and document nature “over there”. In contrast, through a range of different activities, our field guide not only invites investigation and cataloguing of the field that we also comprise, but also challenges what counts as a noteworthy observation regarding the weather and also climate.


Impacts Of Climate Extremes On Terrestrial Productivity, Suhua Wei 2018 The Graduate Center, City University of New York

Impacts Of Climate Extremes On Terrestrial Productivity, Suhua Wei

All Dissertations, Theses, and Capstone Projects

Terrestrial biosphere absorbs approximately 28% of anthropogenic CO2 emissions. This terrestrial carbon sink might become saturated in a future climate regime. To explore the issues associated with this topic, an accurate estimate of gross primary production (GPP) of global terrestrial ecosystems is needed. A major uncertainty in modeling global terrestrial GPP is the parameter of light use efficiency (LUE). Most LUE estimates in global models are satellite-based and coarsely measured with emphasis on environmental variables. Others are from eddy covariance towers with much greater spatial and temporal data quality and emphasis on mechanistic processes, but in a limited number ...


Assessment Of Snow Atmosphere Forcing During Central Idaho Atmospheric Rivers, William Rudisill 2018 Boise State University

Assessment Of Snow Atmosphere Forcing During Central Idaho Atmospheric Rivers, William Rudisill

Boise State University Theses and Dissertations

Atmospheric Rivers (AR) are globally occuring weather features and the primary mechanism through which water vapor moves from the tropics and subtropics towards the mid-latitudes, doing so at rates comparable to the world’s largest terrestrial rivers. AR that encounter mountains often cause extreme precipitation in the form of rain and snow, high winds, and flooding in many watersheds. They account for as much as 20-30% of cool season precipitation in the central Idaho Mountains. In the Northern Hemisphere, seasonal snow cover during Winter and Spring months is the most variable land surface component in space and time, and acts ...


Controls On Deuterium Excess Across Asia, John Bershaw 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 ...


Evaluating Changes To Natural Variability On A Warming Globe In Cmip5 Models, Heather Vazquez 2018 Florida International University

Evaluating Changes To Natural Variability On A Warming Globe In Cmip5 Models, Heather Vazquez

FIU Electronic Theses and Dissertations

Global mean surface temperatures (GMST) warmed in the early 20th century, experienced a mid-century lull, and warmed again steadily until 1997. Observations at the turn of the 21st century have revealed another period of quiescent warming of GMSTs from 1998 to 2012, thus prompting the notion of a global warming “hiatus”. The warming hiatus occurred concurrently with steadily increasing atmospheric greenhouse gas concentrations, sea level rise, and retreating arctic sea ice. The occurrence of the warming hiatus suggests that natural variability continues to be a sizable contributor to modern climate change and implies that energy is rearranged or changed within ...


Aerosol And Meteorological Parameters Associated With The Intense Dust Event Of 15 April 2015 Over Beijing, China, Sheng Zheng, Ramesh P. Singh 2018 Zhejiang University

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 ...


A Preliminary Examination Of Wrf Ensemble Prediction Of Convective Mode Evolution, Bradley R. Carlberg, William A. Gallus Jr., Kristie J. Franz 2018 Iowa State University

A Preliminary Examination Of Wrf Ensemble Prediction Of Convective Mode Evolution, Bradley R. Carlberg, William A. Gallus Jr., Kristie J. Franz

Geological and Atmospheric Sciences Publications

Accurately simulating convective mode evolution can assist forecasters in the severe weather warning process. A few prior studies have examined the skill of simulating convective modes using single, deterministic forecasts. The present study extends the earlier evaluations to a small, four-member ensemble, with each member incorporating varying initial and lateral boundary conditions, microphysics schemes, and planetary boundary layer schemes. Simulated convective modes from thirty-two 12-h simulations were categorized into nine classifications using a classification scheme developed from previous studies. Multiple methods were used to derive forecasts of these convective classifications, creating an hourly deterministic ensemble mode forecast and probabilistic forecasts ...


A Diagnostic Metric For Predicting Tropical Cyclone And Mid-Latitude Floods, Jonathon Klepatzki, Shawn M. Milrad 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 ...

How College Campuses Are Using Social Media During Severe Weather Events, Emmale Davis

Theses and Dissertations

This study explores how college campuses are using social media during severe weather events. This topic surfaced after a tornado devastated Moore, Oklahoma in May 2013 and those displaced flocked to the University of Oklahoma campus after a post made on Twitter went viral prior to an official message being sent out by the university. In order to further explore this topic, a qualitative phenomenological case study was conducted at the following sites: University of Alabama, Missouri Southern State University, University of Oklahoma, and Florida State University. This study included observations of social media posts on Facebook and Twitter on ...

Gis Modeling Of The Prominent Geohazards In Arkansas, Kyle Walker Rowden

Theses and Dissertations

The State of Arkansas is prone to numerous geohazards. This thesis is a twofold study of prominent geohazards in Arkansas: the first fold includes a novel triggerless approach for mass wasting susceptibility modeling applied to the Boston Mountains in NW Arkansas, and the second fold is a GIS-based regression modeling of the extreme weather patterns at the state level. Each study fold is presented in this thesis as a separate chapter embracing a published peer-reviewed paper. In the first paper, I have used the analytical hierarchy process to assign preliminary statistical weights to the most cogent variables influencing mass wasting ...

Recent Climate Warming Drives Ecological Change In A Remote High-Arctic Lake, Lineke Woelders, Jan Lenaerts, Kimberley Hagemans, Keechy Akkerman, Thomas B. Van Hoof, Wim Z. Hoek

University Libraries Open Access Fund Supported Publications

The high Arctic is the fastest warming region on Earth, evidenced by extreme near-surface temperature increase in non-summer seasons, recent rapid sea ice decline and permafrost melting since the early 1990’s. Understanding the impact of climate change on the sensitive Arctic ecosystem to climate change has so far been hampered by the lack of time-constrained, high-resolution records and by implicit climate data analyses. Here, we show evidence of sharp growth in freshwater green algae as well as distinct diatom assemblage changes since ~1995, retrieved from a high-Arctic (80 °N) lake sediment record on Barentsøya (Svalbard). The proxy record approaches ...


An Analysis Of Urban Heat Islands In Kentucky, Logan Mitchell 2018 Western Kentucky University

An Analysis Of Urban Heat Islands In Kentucky, Logan Mitchell

Honors College Capstone Experience/Thesis Projects

The purpose of this research is to increase understanding of the Urban Heat Island (UHI) effect in Kentucky by studying its three largest cities: Louisville, Lexington, and Bowling Green. By examining the UHIs of these three cities, two major attributes can be determined: if there is a relationship between the size of the city by population and the UHI magnitude, and if UHI magnitude follows any diurnal and/or seasonal cycles. Data was collected from weather stations within the three major cities, as well as from weather stations located in the rural areas surrounding them. The length of the time ...


The Impact Of Past Experience With Tornadoes On Future Decisions, Emily Paltz, Michael Hayes 2018 University of Nebraska-Lincoln

The Impact Of Past Experience With Tornadoes On Future Decisions, Emily Paltz, Michael Hayes

Honors Theses, University of Nebraska-Lincoln

Tornadoes are a dangerous threat to public safety. The National Weather Service (NWS), therefore, advises the public to go to an interior room on the lowest level of their houses when a tornado warning is issued for their area. As the NWS Central Region Service Assessment of the Joplin, Missouri Tornado published in July 2011 reveals, however, this is often not the first action taken after learning that there is danger of being hit by a tornado. Rather, people need to seek confirmation from more than one source before following the recommended action. The goal of this research project is ...


Mathematics Of The Significant Tornado Parameter, Aaron Baker 2018 Stephen F Austin State University

Mathematics Of The Significant Tornado Parameter, Aaron Baker

Undergraduate Research Conference

The idea of this project came from my curiosity of weather and especially how severe storms are predicted. There are many parameters used to predict severe weather that use mathematical formulas. After sorting through the parameters, the STP was the one selected due to its use of other parameters for prediction of tornadoes, as well as concepts used in Single and Multi-Variable Calculus, such as areas between curves and vector magnitude and direction, and learning how to use new graphs than what is normally used.

David Ehrensperger

This presentation was part of my unpublished research experience in a CTLE Faculty Learning Community (FLC) during the 2017-2018 academic year. It involved incorporating meteorological sensors in Unmanned Aerial Systems (or UAS) in the pedagogical context of meteorology courses at Embry-Riddle Aeronautical University (ERAU) in Prescott, AZ. The FLC planned the incorporation of UAS sensors and working with the subsequent recorded data into courses during the Fall 2017 semester, implemented the planning during the Spring 2018 semester, and concretely planned to continue similar data gathering activities in future iterations of the courses.

As with all FLCs at ERAU, the commitment ...
