Andrija Mohorovicic, the father of Croatian geophysical research, is widely known as the discoverer of discontinuity between the Earth's crust and mantle. In this study we focus on less well known meteorological research by A. Mohorovicic, specifically on his earliest quantitative documentation of a rotor-type circulation in the bora-type flow on the northern Adriatic. Presented will be an overview of Mohorovicic's research technique and rotor-related contributions from the end of the 19th century, review of the contemporaneous research on the subject, and research on this topic in the 1920's and 1930's, considered to be the seminal work on the subject of atmospheric rotors to date. Mohorovicic's discovery is discussed in the context of the Terrain-induced Rotor Experiment (T-REX), the recently completed international field experiment and research effort focused on the study of atmospheric terrain-induced rotors.
