Isidoro Orlanski (born 1939) is an Argentine-American atmospheric physicist, meteorologist, and ocean scientist. He is known for his groundbreaking contributions to the dynamics of weather systems and ocean currents, especially his work on mesoscale meteorology. He is currently an emeritus professor at Princeton University.[1][2]

Early life and education

[edit]

Orlanski was born in Rivera, Buenos Aires, in 1939 to Jewish immigrants Samuel and Sara Orlanski, who fled Wolkowysk, Poland during the early 20th century pogroms. With the help of the Jewish Colonization Association, which enabled Jewish immigrants from Eastern Europe to farm in Argentina, the Orlanski family settled in rural Argentina before moving to Buenos Aires in the early 1940s.

In 1959, Orlanski enrolled in the Faculty of Exact and Natural Sciences (Spanish: Facultad de Ciencias Exactas) at the University of Buenos Aires, where he studied physics. During his study, Orlanski worked as a programmer for Dr. Rolando Garcia, the dean of the school at the time, assisting U.S. professors visiting the Department of Meteorology. In 1964, Orlanski earned a degree in physics from University of Buenos Aires. In 1965, he received a grant to pursue graduate studies at the Massachusetts Institute of Technology. Under the supervision of Jule Charney, he completed his PhD in 1967 with a thesis titled Instability of Frontal Waves, which earned the Carl Gustav Rossby Award for best thesis in the Atmospheric and Oceanic Sciences program.[3][1]

Career

[edit]

Before his anticipated return to Argentina, Orlanski followed Jule Charney's advice to spend a year in Washington, D.C., joining the Geophysical Fluid Dynamics Laboratory (GFDL), where he worked with Joseph Smagorinsky.[4] The GFDL, under the leadership of Dr. Joseph Smagorinsky, was pioneering the development of numerical models for weather forecasting and climate assessment.[5] Orlanski ultimately decided to spend his career at GFDL. He relocated with the lab to Princeton University, New Jersey, where he became a lecturer in Atmospheric and Oceanic Sciences, a collaboration between the lab and Princeton.[6]

By 1980, GDFL had grown to 134 staff members, with Orlanski being appointed the lab's first Deputy Director.[2] During a sabbatical in Argentina in 1985, he established a center for numerical modeling that became the Centro de Investigaciones para el Mar y la Atmósfera (CIMA).[7] CIMA grew into a leading institution in Latin America, attracting scientists and students globally. Orlanski retired from GFDL in 2007 but continued teaching at Princeton University until 2017, retiring as a lecturer with the rank of Full Professor.[2]

Research

[edit]

Orlanski’s work has been instrumental in mesoscale meteorology. He introduced the terms Meso-alpha, Meso-beta, and Meso-gamma to classify the horizontal scales of atmospheric processes, widely used in limited area modeling. The primary purpose of Orlanski’s classification of mesoscale phenomena was to assist modelers in designing limited-area models for mesoscale prediction. This framework was pivotal in the design of field experiments for mesoscale observations, as well as in defining the spatial and temporal scales necessary for forecast models. Moreover, it took over two decades for both numerical models and observational technologies to achieve an acceptable level of accuracy in this domain. His research on boundary conditions for unbounded hyperbolic flows has applications beyond meteorology, influencing fields like hydrology and flow chemistry.[8]
