A 20-Year Synoptic Climatology of the South Plains Dewpoint / Dryline
A 20-year climatology of the South Plains dryline has been constructed using hourly surface data from the United States surface-observing network. Data from the time frame 1975-1995 is objectively analyzed from over 50 surface stations across the states of CO/KS/NM/OK/TX and an algorithm to detect the presence of the dryline is employed. This analysis reveals patterns in the frequency of dryline occurrence and within the study area. Mean positions of the dryline calculated by time-of-day and time-of-year along with the range of motion the dryline exhibits on both a daily and a monthly basis will be examined . It is hoped that the study will give forecasters a historical perspective on dryline morphology.
