Arianna Varuolo-Clarke

Graduate Student

Arianna is a Ph.D. candidate at the Lamont-Doherty Earth Observatory of Columbia University in the City of New York. She studies observed and simulated precipitation trends and variability in southeastern South America.  She is co-advised by Jason Smerdon at the Lamont-Doherty Earth Observatory of Columbia University and Park Williams at the University of California, Los Angeles.

Arianna earned her M.S. at the School of Marine and Atmospheric Science at Stony Brook University where she was advised by Kevin Reed. Her M.S. research sought to understand how global climate models simulate the northerly extent of precipitation in the North American monsoon and the role that resolution plays in their ability to do so.

Arianna graduated from Northern Vermont University with a B.S. in Atmospheric Science.
