AREAL AND TEMPORAL OCCURRENCE OF HIGH DEW POINTS AND ASSOCIATED TEMPERATURES

Abstract
The report is a condensation of information currently available in the Earth Sciences laboratory concerning the frequency of occurrence of high dew points and the temperatures that are associated with high dew points. In the first section of the report, graphs showing the frequency of occurrence of high dew points and temperatures at 78 stations for the midseason months of January, April, July, and October are presented. Tables showing the maximum, minimum, and median temperatures associated with dew points above 75F supplement the information on the frequency graphs. This information is presented to illustrate the likelihood of occurrence of high dew points and high temperatures. In the second section of the report, maps showing the frequency of occurrence each month of dew points above 76F, 80F, and 84F at 215 stations between latitudes 40 N and 40 S are presented. Data for each station are presented on circular graphs, making possible quick comprehension of the seasonal pattern of occurrence of high dew points at the individual stations, and the inclusion of the circular graphs on the maps gives some insight into the areal distribution of the occurrence of high dew points.
