Characterizing Temperature Variability States Across Southern South America And Associated Synoptic-Scale Meteorological Patterns, Judah Adam Detzer
Characterizing Temperature Variability States Across Southern South America And Associated Synoptic-Scale Meteorological Patterns, Judah Adam Detzer
Dissertations and Theses
The aim of this thesis is to understand spatiotemporal temperature variability in southern South America by identifying overarching temperature variability states and their associated synoptic-scale meteorological patterns. Further, the temporal frequency of occurrence of those temperature variability states is investigated as is the role of recurrent low-frequency modes of climate variability (El Niño Southern Oscillation and the Southern Annular Mode) on temperature variability. K-means cluster analysis is used to group all months during the period 1980-2015 into four primary categories for summer and winter separately. Monthly maps of temperature anomalies are provided as input to the k-means algorithm and the …

Large Scale Climate Oscillation Impacts On Temperature, Precipitation And Land Surface Phenology In Central Asia, Kirsten M. De Beurs, Geoffrey Henebry, Braden C. Owsley, Irina N. Sokolik
GSCE Faculty Publications
Central Asia has been rapidly changing in multiple ways over the past few decades. Increases in temperature and likely decreases in precipitation in Central Asia as the result of global climate change are making one of the most arid regions in the world even more susceptible to large-scale droughts. Global climate oscillations, such as the El Ni ̃no–Southern Oscillation, have previously been linked to observed weather patterns in Central Asia. However, until now it has been unclear how the different climate oscillations act simultaneously to affect the weather and subsequently the vegetated land surface in Central Asia.We fit well-established land …
Microclimate Variability Of Select Toronto Neighbourhoods Under Hot Summertime Conditions, Timothy Wiechers
Microclimate Variability Of Select Toronto Neighbourhoods Under Hot Summertime Conditions, Timothy Wiechers
Electronic Thesis and Dissertation Repository
Micrometeorological variability within cities has important implications for urban air and water quality, building energy consumption, and human health and thermal comfort. However, the monitoring of microscale climate is not routinely conducted. In most instances, primary meteorological observations are made under reproducible standard conditions (typically at an airport); but these open field observations tend to be unrepresentative of the intra-urban meteorological conditions.
This thesis used an alternative approach of conducting mobile traverse measurements using vehicle-mounted sensors to characterize the microclimates of Toronto, ON under hot, summertime weather conditions. Sampling occurred along two routes and incorporated sampling 8 intra-urban neighbourhoods with …
Changing Snow Seasonality In The Highlands Of Kyrgyzstan, Monika Tomaszewska, Geoffrey Henebry
Changing Snow Seasonality In The Highlands Of Kyrgyzstan, Monika Tomaszewska, Geoffrey Henebry
GSCE Faculty Publications
Few studies have examined changing snow seasonality in Central Asia. Here, we analyzed changes in the seasonality of snow cover across Kyrgyzstan (KGZ) over 14 years from 2002/03–2015/16 using the most recent version (v006) of MODIS Terra and Aqua 8 day snow cover composites (MOD10A2/MYD10A2). We focused on three metrics of snow seasonality—first date of snow, last date of snow, and duration of snow season—and used nonparametric trends tests to assess the significance and direction of trends. We evaluated trends at three administration scales and across elevation. We used two techniques to assure that our identification of significant trends was …

This study considers the various factors that regulate nutrients supply in the Red Sea. Multi-sensor observation and reanalysis datasets are used to examine the relationships among dust deposition, sea surface temperature (SST), and wind speed, as they may contribute to anomalous phytoplankton blooms, through time-series and correlation analyses. A positive correlation was found at 0–3 months lag between chlorophyll-a (Chl-a) anomalies and dust anomalies over the Red Sea regions. Dust deposition process was further examined with dust aerosols’ vertical distribution using satellite lidar data. Conversely, a negative correlation was found at 0–3 months lag between SST anomalies …

Geochemistry Of Archaeological And Marine Environments In Southwest Maine, Heather L. Bushie
Thinking Matters Symposium Archive
Two archaeological excavations for the University of Southern Maine collected sediment columns from select units for geological and chemical analysis. The Spiller Farms site is a Native American site located in Wells, Maine marking a transition period between the Pleistocene and Holocene epochs, 12,000 BP. The Malaga Island site was a historic mixed-race community at the north end of Casco Bay where sediment columns were obtained in near-shore and subtidal zones. The samples obtained from Malaga Island have been radiocarbon dated to 3800 +/- 30 BP at 23 meters below the low-tide line. X-ray fluorescence (XRF) analysis is being conducted …
Interannual Variations Of Snowfall In The Lower Peninsula Of Michigan And Impacts Of Local And Remote Meteorological Conditions, Nirjala Koirala
Interannual Variations Of Snowfall In The Lower Peninsula Of Michigan And Impacts Of Local And Remote Meteorological Conditions, Nirjala Koirala
Masters Theses
Inter-annual variation of snowfall and its relation to climate indices will help clarify and improve the prediction of total snowfall in the Lower Peninsula of Michigan (LPM). This study examines the trend and variability of annual snowfall (November- March) using 8 homogeneous weather stations in the LPM. The statistical relationship between snowfall and air temperature, Sea Surface Temperature (SST), North Atlantic Oscillation (NAO), Pacific Decadal Oscillation (PDO) and Maximum Ice Coverage(MIC) of Lake Michigan is calculated. The long-term trend in the snowfall data set from 1950 to 2015 is removed before any statistical correlation analysis is conducted. My analysis suggests …

The Influence Of Northern Hemisphere Teleconnections On The Geography Of Pacific Tropical Cyclone Genesis, Nicholas Ray Adkins
The Influence Of Northern Hemisphere Teleconnections On The Geography Of Pacific Tropical Cyclone Genesis, Nicholas Ray Adkins
Theses, Dissertations and Capstones
The research in this thesis used statistical and spatial analysis methods to test the influence of six Northern Hemisphere teleconnection patterns on the latitude and longitude components of tropical cyclogenesis occurring in the eastern and western North Pacific Ocean basins for the period 1979-2016. The Pacific-North American (PNA), West Pacific (WP), El Niño Southern Oscillation (ENSO), Pacific Decadal Oscillation (PDO), Madden-Julian Oscillation (MJO), and Quasi-Biennial Oscillation (QBO) teleconnection patterns were examined independently and in combination for association with variations in cyclogenesis geography. Four of the six teleconnection patterns were found to exert an influence on cyclogenesis latitude and/or longitude in …
