Heather Archambault (age 41) is an American meteorologist who conducts research related to synoptic-dynamics with a focus on tropical meteorology 1. She is part of the American Meteorological Society and the American Geophysical Union 2. She has aided in important discoveries about the effect of diabatic outflow from tropical cyclones on the jetstream that work to further our understanding of tropical meteorology. Education Heather obtained her B.S. in Meteorology from Pennsylvania State University in 2002. Heather then attended University of Albany where she received her Master’s in Atmospheric Science in 2005. She also received her Ph.D. in Atmospheric Science from the University of Albany in 20113.
Career Upon receiving her Ph.D. from the University of Albany, Heather Archambault joined a postdoctoral program in September 2011 at the Naval Postgraduate School’s Department of Meteorology in Monterey, California. There, she worked with Professor Pat Harr and Professor Rich Moore on the National Research Council as a research fellow3.
After completing her postdoctoral research, Heather worked as a program manager, specifically as a Program Specialist III, at the University Corporation for Atmospheric Research’s joint office for Science Support in Silver Spring, Maryland from 2014 to September 2016.
In September 2016, Heather became a Management and Program Analyst at the NOAA/OAR/Climate Program Office in Silver Springs, Maryland. While in this position, she co-managed an external research grants program in order to make progress in NOAA’s climate modeling and prediction capabilities.
Heather then became the Associate Director of the NOAA Geophysical Fluid Dynamics Laboratory in Princeton, New Jersey 2.
Currently, Heather works as a weather analyst at the investment fund Citadel in Greenwich, Connecticut 1.
Awards and Fellowships Heather has received several awards and fellowships for her work in meteorology. These awards include: the American Meteorological Society Editors’ Award (2017) which she received for her work in reviewing articles. the National Research Council Postdoctoral Fellowship from the Naval Postgraduate school which she received from 2011 to 2014. the Award for Outstanding Poster Presentation (2013) from the Davos Atmosphere and Cryosphere Assembly in Davos, Switzerland. the Travel awards (2012) from the International Association of Meteorology and Atmospheric Sciences and World Climate Research Programme International Commission on Dynamic Meteorology on the Dynamics and Predictability of High Impact Weather and Climate Events in Kunming, China. The Distinguished Doctoral Dissertation Award (2012) from The Colleges of Arts and Sciences at the University of Albany. The Narayan R. Gokhale Distinguished Research Scholarship Award (2012) from the University of Albany. The Award for Outstanding Poster Presentation (2011) from the WCRP US-CLIVAR Open Science Conference in Denver, Colorado. The Advanced Study Program Graduate Student Visitor Fellowship (2010) at the Mesoscale and Microscale Meteorology Division, NCAR, Boulder, Colorado 2.
Research Heather has been involved in 12 peer-reviewed research articles that focus largely on synoptic-dynamic meteorology with a focus on the tropics.
Two of the articles that she was the lead author on were completed as part of her Ph.D. dissertation. Findings from Influence of large-scale flow regimes on cool-season precipitation in the northeastern United States emphasized the connections between large scale atmospheric circulations on precipitation over the northeastern portion of the United States. The Pacific North American circulation, which impacts the jetstream (fast winds aloft) over the US, had significant influences on precipitation over the region for both positive and negative phases. Negative PNA phases brought above-average cool-season precipitation to the northeast, including more lighter and moderate events. Positive PNA phases brought below-average cool-season precipitation to the northeast. The North Atlantic Oscillation (driven by differences in sea-surface temperatures and land over and around the North Atlantic) had no significant impact on precipitation4.
The second article, Relationships between large-scale regime transitions and major cool-season precipitation events in the northeastern United States, looked into similar aspects of precipitation over the northeast, but specifically on major precipitation events and their connection to large-scale circulations. In this paper, it was found that positive-to-negative transitions in the North Atlantic Oscillation were associated with more frequent major precipitation events over the northeast United States5.
Heather was the lead author on multiple papers examining the impact of recurving (moving northward) tropical cyclones on the jetstream over the North Pacific. It was found that the diabatic outflow from these tropical cyclones, or the wind directed away from a tropical cyclone, worked to create ridges (northward extending bends in the jetstream for the northern hemisphere) and in general amplified the jetstream pattern (deeper troughs and ridges).
