Abstract

Water levels and basin data of the Laurentian Great Lakes were related to two major meteorological indices. Historical fluctuations have lead to suggestions that GLWL fluctuations are due to climate change and increased climatic variability of the local region. Related to climate change, increased frequency and intensity of the El Nino/Southern Oscillation (ENSO) phenomenon indicates that Lake level fluctuation may be related. This thesis considers the relationship between fluctuations of Great Lakes water levels and the El Nino/Southern Oscillation using data collected from 1950 to 1999. Water level data and net basin supply data collected monthly over this time span for Lakes Superior, Michigan-Huron, Erie and Ontario. The two major meteorological indices used to study water levels and basin data are the Southern Oscillation Index (SOI) and the Multivariate ENSO Index (MEI) which, were statistically modeled using Box-Jenkins time series analysis. Time series analysis was used to determine how well each model could predict the historical patterns in the time series. Additionally, this thesis attempted to determine how well historical lake levels were described by the Multivariate ENSO Index (MEI), which is used to calculate ENSO parameters.
