PEI Faculty Seminar: “The Midlatitude Surface Westerlies: Why They Exist and How They Will Change as the Earth Warms”
Isaac Held, senior meteorologist in atmospheric and oceanic sciences and lecturer with the rank of professor in geosciences and atmospheric and oceanic sciences, will present “The Midlatitude Surface Westerlies: Why They Exist and How They Will Change as the Earth Warms,” at 12:30 p.m. Tuesday, Feb. 4, in Guyot Hall, Room 10.
The midlatitude surface westerlies are a critical component of the atmosphere’s large-scale structure that are closely associated with subtropical aridity and ocean circulation. Models project poleward movement of the surface westerlies with climate warming. Held will discuss how our qualitative understanding of the distribution of surface winds has evolved over the past century — and the challenge of combining that understanding with computer simulations to inform future projections.
Held is the first speaker in the Spring 2020 PEI Faculty Seminar Series, which is free and open to the public. Additional speakers and dates in this series are:
