Joanne Simpson

Simpson's teaching and research career at universities includes time at the University of Chicago, New York University, Illinois Institute of Technology, Woods Hole Oceanographic Institution, UCLA, the Environmental Satellite Services Administration (ESSA), the National Oceanic and Atmospheric Administration (NOAA), University of Virginia, and the National Aeronautics and Space Administration (NASA). ==Research==

In 1958, Simpson (then 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. The pair realized this must be due to moist convection that started near the surface that continued rising relatively adiabatically to near . They called these clouds "undiluted chimneys" but they would later be commonly referred to as hot towers. 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, Simpson became the director of Project Stormfury while chief of the Experimental Meteorology Branch of the Environment Satellite Services Administration's Institute for Atmospheric Sciences. She eventually became NASA's lead weather researcher and authored or co-authored over 190 articles. ==Honors and awards==

The inaugural recipient was Kerry H. Cook. ==Personal==

Simpson was married three times. In 1944, she married meteorologist Victor Starr; the two divorced in 1947. In 1948, she married her second husband, physics instructor Willem Van Rensselaer Malkus, who would go on to be a professor of applied mathematics at MIT. She and Malkus divorced in 1964 and, in January 1965, she married meteorologist Robert Simpson, whom she first met in 1943 and with whom she already had a professional relationship. Simpson 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." in Washington, D.C. 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. Simpson died March 4, 2010, in Washington D.C., at the age of 86 from multiple organ failure. She is buried, along with her husband Robert, at Rock Creek Cemetery in Washington, D.C. ==References==
