Abstract
Two methods are developed for translating monthly mean circulation patterns into the accompanying surface temperature anomalies. Using a system of graphical correlation, temperature anomalies are deduced objectively from the curvature of isobars, pressure departure from normal, and air parcel trajectory on monthly mean 10,000-ft., or 700-mb. charts. The scheme is simplified by using the anomalies of flow and pressure as parameters. The results are extended for use on 5-day mean 700-mb. charts and further possibilities for improving the objective technique are considered.
