Evaluation of Influences of ENSO Events on Changes in Temperature Extremes and Energy Consumption in South Florida
Publication: World Environmental and Water Resources Congress 2020: Groundwater, Sustainability, Hydro-Climate/Climate Change, and Environmental Engineering
ABSTRACT
El Niño southern oscillation (ENSO) events throughout the world are known to influence regional (or local) hydroclimatic variability and changes in essential climatic variables (i.e., temperature, precipitation, and others). Variations in temperature extremes influenced by ENSO may lead to spatial and temporal variability of energy consumption and better management strategies by energy utilities. The focus of this study is to assess the possible influences of El Niño southern oscillation (ENSO) events on regional temperature characteristics and extremes along with residential energy consumption in South Florida. The region of interest comprising three counties namely Miami-Dade, Broward, and Palm Beach. Evaluation of ENSO events on temperature is carried out using long-term monthly mean, minimum, and maximum temperature data from 1961–2018 from serval sites located in these counties. Joint variation of monthly electricity consumption obtained from a local power utility and temperature data available from the year 2001 to 2018 are used in the study. Temporal windows that coincide with three phases of ENSO (i.e., warm, cool, and neutral) are used to evaluate changes in temperature and energy consumptions. Nonparametric hypothesis tests are used to confirm statistically significant changes in temperature and energy in different phases of ENSO. This study is expected to provide insights into the possible spatial and temporal influences of ENSO events on temperature and residential electricity consumption for South Florida. Preliminary results suggest that spatially non-uniform variations in temperature influenced by El Niño and La Niña events affect the residential energy consumption in South Florida. Insights gained from this study can help local power utilities to plan and manage energy production and distribution for future ENSO events.
