Book excerpt: 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.
