Bruce Anderson, Dan Gianotti and Guido Salvucci publish new findings in the Journal of Hydrometeorology
Earth & Environment Professor Bruce Anderson, PhD candidate Dan Gianotti and Professor Guido Salvucci have published a new paper in the Journal of Hydrometeorology. The paper is titled “Characterizing the potential predictability of seasonal, station-based heavy precipitation accumulations and extreme dry-spell durations.” It can be downloaded here.
Using daily precipitation data collected over the last 80+ years at stations across the US, the paper assesses the potential for predicting seasonal precipitation extremes such as extreme dry spells leading to droughts like those in California or heavy precipitation events like those that occurred this past winter in Boston. Generally, predictability is higher for heavy precipitation events than droughts, and is enhanced during the cool season compared to the warm season. That said, here in the Northeast, wintertime precipitation extremes have very little predictability to them. Or put another way, the preponderance of snow this past winter can, for the most part, just be chalked up to bad luck.
Gianotti is a PhD candidate in Earth Sciences who is jointly advised by Anderson and Salvucci.
The Earth & Environment Graduate Student Seminar Series continues tomorrow at 3 PM in CAS 313.
Tomorrow’s seminar will feature Brittain Briber’s presentation on “Vegetation productivity changes following conversion from forest to urban land uses” and Samuel Tuttle‘s presentation on “Empirical Evidence of Positive and Negative Soil Moisture-Precipitation Feedbacks Across the U.S.”
All faculty and students of the department are expected to attend and complete a short evaluation for each presenter.
Brittain Briber is a PhD candidate in Geography focusing on urban ecology and atmospheric science; he is advised by Assistant Professor Lucy Hutyra.
Samuel Tuttle is a PhD candidate in Earth Sciences focusing on hydrology; he is advised by Professor Guido Salvucci.
Earth & Environment Graduate Student Seminars will begin for the Spring semester this Friday, January 23rd, at 3 PM in CAS 313.
This weeks presenters will be Nicoletta Leonardi presenting on “Salt marsh resistance to violent storms and hurricanes;” Angela Rigden presenting on “Multi-decadal estimation of trends in evapotranspiration from weather station data using a new approach;” and Kira Sullivan-Wiley on “What shapes risk perception? An analysis form a high-risk agricultural area of Uganda.”
All students and faculty in the department are expected to attend and audience members will be asked to complete a short evaluation to help provide feedback to the students.
Nicoletta Leonardi is a PhD candidate in Earth Science with an emphasis on coastal geomorphology working with Associate Professor Sergio Fagherazzi. Angela Rigden is a PhD candidate in Earth Science with an emphasis on hydrology working with Professor Guido Salvucci. Kira Sullivan-Wiley is a PhD candidate in Geography with an emphasis on valuation and realization of ecosystem services; her advisor is Assistant Professor Anne Short.
The paper, “The Potential Predictability of Precipitation Occurrence, Intensity and Seasonal Totals over the Continental United States,” was published in September and can be accessed online.
The study breaks the variability of precipitation into “weather” and “climate” components and finds that most of the opportunity for seasonal climate prediction lies in precipitation occurrence rather than intensity or seasonal total precipitation.
Dan Gianotti is a Ph.D. candidate working with Anderson and Salvucci on hydrology, climate systems, and the interactions between people and water. To learn more about Gianotti’s work, check out his website.

Tuttle’s talk, “Using Large-Scale Precipitation to Validate AMSR-E Satellite Soil Moister Estimates by Means of Mutual Information,” was award an OSPA in the category of Hydrology.
Tuttle, who received his Masters in 2011 and is now a PhD Candidate in Earth Science, is advised by Earth and Environment Professor Guido Salvucci.
The Outstanding Student Paper Awards are given out to the top 3 to 5% of students in each area of focus at AGU (OSPA).
Several members of the Department of Earth and Environment will be in San Francisco, California this week participating in the annual AGU Fall Meeting.
During this week long conference, several faculty members, researchers, and students will give lectures and present posters.
