Optimum Period of Record.
Abstract
Percentage frequency of occurrence of ceilings and visibilities, as well as monthly means of temperature, precipitation, and pressure, were examined for their relative representative application to current climatatology. Several U.S. ans overseas locations showed climatological changes that rendered normals ineffective as tools for describing or predicting current weather conditions. Monthly values wer compared to running means for 1 through 31 antecedent years. The means closet to the actual value was tallied as the best. This scoring system was applied to periods of record beginning as early as the 1700's and usually showed that shorter means of 1 to 7 years were frequently closet to actual values. (Author)
