The objects of the American Meteorological Society are "the development and dissemination of knowledge of meteorology in all its phases and applications, and the advancement of its professional ideals." The organization of the Society took place in affiliation with the American Association for the Advancement of Science at Saint Louis, Missouri, December 29, 1919, and its incorporation, at Washington, D. C., January 21, 1920. The work of the Society is carried on by the Bulletin, the Journal, and Meteorological Monographs, by papers and discussions at meetings of the Society, through the offices of the Secretary and the Executive Secretary, and by correspondence. All of the Americas are represented in the membership of the Society as well as many foreign countries.

Five-day mean and daily meteorological data observed since 1949 are analyzed empirically in order to derive useful climatological and forecasting relationships between surface weather elements and the circulation pattern. The synoptic climatology of 5-day precipitation, surface temperature, 700-1000-mb. thickness, and sea level pressure is investigated by constructing fields of simple linear correlation between these elements and the simultaneous anomaly of 700-mb. height over North American and adjacent oceans. The relation of precipitation and temperature to the field of sea level pressure is studied in a similar fashion. On the basis of the analogy are drawn concerning the association between each weather element and other meteorological factors. Schematic models are then constructed showing preferred portions of the circulation pattern at 700-mb. and sea level for opposite extremes of weather in different parts of the United States.
