Summary
Abstract: [from the data set documentation]

Historical accounts of the voyages of the Manila galleons derived from
the Archivo General de Indias (General Archive of the Indies, Seville,
Spain) are used to infer past changes in the atmospheric circulation
of the tropical Pacific Ocean. It is shown that the length of the
voyage between Acapulco, Mexico, and the Philippine Islands during the
period 1590-1750 exhibits large secular trends, such that voyages in
the middle of the seventeenth century are some 40% longer than those
at the beginning or at the end of the century, and that these trends
are unlikely to have been caused by societal or technological factors.
Analysis of a series of "virtual voyages," constructed from modern
wind data, indicates that sailing time to the Philippines depended
critically on the strength of the trade winds and the position of the
western Pacific monsoon trough. These results suggest that the
atmospheric circulation of the western Pacific underwent large,
multidecadal fluctuations during the seventeenth century.
