Kerry Emanuel (1955–)

Basic Facts

  • Full name: Kerry Andrew Emanuel
  • Born: 21 April 1955, USA
  • Status: Living (age 70)
  • Current position: Professor Emeritus of Atmospheric Science, MIT

Early Life

Emanuel grew up in the Midwest, where he developed an early fascination with weather. According to his older brother, “from the age of 2, I would crawl to the window whenever there was a thunderstorm.” During his teenage years in Florida, he observed hurricane edges firsthand – experiences that shaped his future career.

Education

Year Degree / Institution Notes
– B.S. in Earth and Planetary Sciences, MIT  
1978 Ph.D. in Meteorology, MIT Thesis: “Inertial Stability and Mesoscale Convective Systems”; Advisor: Jule Charney

At MIT, he studied under some of the central figures of modern meteorology: Jule Charney, Fred Sanders, and Edward Lorenz.

Career

  • 1978–1981: Faculty position at UCLA. During this period, took a sabbatical to film tornado wind speeds in Texas and Oklahoma.
  • 1981–2022: Faculty member, Department of Meteorology (later Department of Earth, Atmospheric and Planetary Sciences), MIT.
  • 2011: Co-founded the Lorenz Center at MIT with Daniel Rothman, named in honor of Edward Lorenz.
  • 2022: Retired from teaching after 41+ years at MIT; continues research through the Lorenz Center.

Major Scientific Contributions

Hurricane Potential Intensity Theory (1986)

Emanuel’s most foundational contribution. In “An Air-Sea Interaction Theory for Tropical Cyclones. Part 1: Steady-State Maintenance” (1986), he derived from first principles – using only pencil-and-paper analysis and physical reasoning – a quantitative upper bound on hurricane intensity given atmospheric and oceanic conditions. This potential intensity (PI) theory has held up remarkably well over decades of comparison with observations and underpins current methods of predicting hurricane intensity and its response to climate change.

Hypercanes (1994)

Introduced the theoretical concept of “hypercanes” – hypothetical extreme hurricanes that could form if sea surface temperatures increased by 15 degrees C beyond historical records.

Climate Change and Hurricanes

Emanuel explored how warming sea surface temperatures would affect hurricanes. His research demonstrated that global warming would likely increase hurricane intensity while potentially decreasing their frequency. In a March 2008 paper in the Bulletin of the American Meteorological Society, he put forward this conclusion.

Flood Risk Assessment

Emanuel developed hurricane models used by the First Street Foundation to assess the true flood risk of every property in the United States. He has called this work potentially his “most substantive contribution”: “I think it’s transformative.”

Comments on Edward Lorenz

Emanuel provided one of the most memorable assessments of Lorenz’s legacy. When Lorenz died in 2008, Emanuel said:

“By showing that certain deterministic systems have formal predictability limits, Ed put the last nail in the coffin of the Cartesian universe and fomented what some have called the third scientific revolution of the 20th century, following on the heels of relativity and quantum physics.”

He added: “He was also a perfect gentleman, and through his intelligence, integrity and humility set a very high standard for his and succeeding generations.”

Personality and Public Engagement

  • Characterized as a brilliant theoretician who genuinely cares about mentoring students.
  • Strongly committed to public outreach on climate science.
  • Has actively opposed both climate denial and what he views as irrational opposition to nuclear energy. In 2013, he co-authored an open letter with leading experts advocating nuclear power as essential for addressing climate change.
  • In 2012, after speaking at a climate conference for Republican voters, received threatening emails following public exposure of his contact information on blogs.

Awards and Honors

  • Carl-Gustaf Rossby Research Medal, AMS
  • Time 100 most influential people (2006)
  • Member, U.S. National Academy of Sciences (2007)
  • Member, American Philosophical Society (2019)
  • Foreign Member of the Royal Society (FRS, 2020)

Connections to Other Scientists

  • Jule Charney: Doctoral advisor at MIT.
  • Edward Lorenz: Colleague at MIT; Emanuel became one of the foremost interpreters and advocates of Lorenz’s legacy.
  • Fred Sanders: Mentor at MIT in synoptic meteorology.
  • Daniel Rothman: Co-founded the Lorenz Center (2011).
