Increasing global temperatures lead to higher rates of evaporation. Higher evaporation rates and the ability of a warmer atmosphere to hold more water vapor can contribute to more frequent and extreme precipitation events, provided that sufficient surface moisture is available. This project analyzed temperature and precipitation data from the National Climatic Data Center for the past 50 years to determine if average annual temperature and precipitation totals have been rising, and whether there was a positive correlation between temperature and precipitation. The results suggest that each of the urban areas have experienced a significant increase in temperature as well as precipitation. An examination of decadal averages reveals the association between the two variables is moderately strong. Further research will examine other regions of the U.S. and evaluate the seasonality of this relationship.

Graduating Senior, Space Physics, Embry-Riddle Aeronautical University, Daytona Beach, FL, USA

Samantha Demarco is currently one of the McNair Program’s graduating seniors. While pursuing her Bachelor of Science in space physics, her research interests revolved around studying the sun’s magnetic field, climatology, and the auroras. She is currently working on a research project dealing with climate changes that have been observed throughout the United States in general, and more specifically, in the northeast region of the country. She plans to pursue her M.S. degree in the fall of 2012.
