Paul Rowland Julian (born October 12, 1929), a Fellow of the American Meteorological Society, is an American meteorologist who served as a longtime staff scientist at the National Center for Atmospheric Research (NCAR), was co-author with Roland Madden of the study establishing the Madden–Julian oscillation (MJO), and contributed to the international, multi-institutional Global Atmospheric Research Program (GARP), Tropical Wind, Energy Conversion, and Reference Level Experiment (TWERLE), and Tropical Ocean-Global Atmosphere (TOGA) meteorology research programs.
[1] Julian joined the National Center for Atmospheric Research (NCAR),[5] an early program of the National Science Foundation, as a staff scientist in 1962, two years into NCAR's existence[6] There, he was a member of the Climate Analysis Section (CAS) in the CGD (Climate and Global Dynamics) area.
[13][14] Julian worked concurrently and later from the Mathematics Department at Dalhousie University in Halifax, Nova Scotia, where he continued effort associated with the Global Atmospheric Research Program (GARP), e.g., serving on the workshop organizing committee for the First GARP Global Experiment (FGGE) and in other atmospheric research related activities.
[15][16] In 1998, Julian and collaborators contributed to an important international review of the decade-long Tropical Ocean-Global Atmosphere (TOGA) observing system (>400 citations as of May 2014).
[17] As of 2014, Julian continues in the position of longstanding active Fellow of the American Meteorological Society (AMS).
