Abstract
THE Meteorological Magazine of December 1939 contains a summary by Prof. S. Chapman of his presidential address to the Association for Meteorology at the Washington Assembly of the International Union for Geodesy and Geophysics last September, the subject being the lunar tide in the atmosphere. The author describes the difficulty that was met when the detection of this lunar tide, achieved first by Lefroy in 1842 for St. Helena, was attempted for higher latitudes, which resulted in a succession of failures that was not broken until his own determination in 1918 of the very small Greenwich air tide, from sixty-four years of hourly data. From that year, when the tide was known for three tropical stations and one non-tropical, progress was rapid, and the rate of determination by Prof. Chapman and his assistants was increased threefold in 1930 through a loan of Hollerith machines by the British Tabulating Machine Co. Now the tide has been determined for more than fifty places.
