Sir Gilbert Thomas Walker CSI FRS (14 June 1868 – 4 November 1958) was an English physicist and statistician of the 20th century. Walker studied mathematics and applied it to a variety of fields including aerodynamics, electromagnetism and the analysis of time-series data before taking up a teaching position at the University of Cambridge. Although he had no experience in meteorology, he was recruited for a post in the Indian Meteorological Department where he worked on statistical approaches to predict the monsoons. He developed the methods in the analysis of time-series data that are now called the Yule-Walker equations. He is known for his groundbreaking description of the Southern Oscillation,[2] a major phenomenon of global climate, and for discovering what is named after him as the Walker circulation, and for greatly advancing the study of climate in general. He was also instrumental in aiding the early career of the Indian mathematical prodigy, Srinivasa Ramanujan.

From p. 283: "There is also a slight tendency two-quarters later towards an increase of pressure in S. America and of Peninsula [i.e., Indian] rainfall, and a decrease of pressure in Australia : this is part of the main oscillation described in the previous paper* which will in future be called the 'southern' oscillation."
