Joanne Simpson (formerly Joanne Malkus, born Joanne Gerould; March 23, 1923 – March 4, 2010) was the first woman in the United States to receive a Ph.D. in meteorology, which she received in 1949 from the University of Chicago.[1][2][3] Simpson received both her undergraduate and graduate degrees from the University of Chicago, and did post-doctoral work at Dartmouth College.[4] Simpson was a member of the National Academy of Engineering, and taught and researched meteorology at numerous universities as well as the federal government. Simpson contributed to many areas of the atmospheric sciences, particularly in the field of tropical meteorology. She has researched hot towers, hurricanes, the trade winds, air-sea interactions, and helped develop the Tropical Rainfall Measuring Mission (TRMM).
In 1958, Malkus collaborated with Herbert Riehl and calculated the average moist static energy and how it varied vertically throughout the atmosphere. They noted that at altitudes up to approximately 750 hPa the moist static energy decreased with height. Above 750 hPa, the moist static energy increased with height which had neither been observed or explained before. Riehl and Malkus realized that this must be due to moist convection that started near the surface that continued rising relatively adiabatically to near 50,000 feet (15,000 m). They called these clouds "undiluted chimneys" but they would later be commonly referred to as hot towers.[6] They estimated that it would take less than 5,000 of these towers daily throughout the tropics to result in the moist static energy profile they observed.
By 1966, she became the director of Project Stormfury while chief of the Experimental Meteorology Branch of the Environment Satellite Services Administration's Institute for Atmospheric Sciences.[7] She eventually became NASA's lead weather researcher and authored or co-authored over 190 articles.
1983 Recipient of the AMS's Carl-Gustaf Rossby Research Medal, its highest honor, for "outstanding contributions to man's understanding of the structure of the atmosphere."
2021 American Meteorological Society established the Joanne Simpson Tropical Meteorology Research Award granted to researchers who make outstanding contributions to advancing the understanding of the physics and dynamics of the tropical atmosphere. The inaugural recipient was Kerry H. Cook.
Personal
She is quoted as saying winning the Rossby Medal in 1983 made her feel "it isn't really so ridiculous that I did all of this. I'm not really a freak; I am a member of the community."
Yet, poignantly, in an article published in the Annals of the New York Academy of Sciences, she was quoted as saying "I am not convinced that either the position, rewards or achievements have been worth the cost. My personal and married life and child raising have surely suffered from the professional attainments I have achieved."
Her brother Daniel C. Gerould was the Lucille Lortel Distinguished Professor of Theatre and Comparative Literature at the Graduate Center, City University of New York and Director of Publications of the Martin E. Segal Theatre Center. Her husband was hurricane expert Robert Simpson. Her former husband Willem Van Rensselaer Malkus (1923-2016) was a professor of applied mathematics at MIT.
Simpson died March 4, 2010, in Washington D.C., surrounded by her family.
