Abstract : 12TH Weather Squadron (previously 4th Weather Wing) has, for the past several years, been conducting applied research into the field of computer-derived weather map types. The aim has been to incorporate map typing techniques into a terminal forecast system. The paper is the latest in a series of technical reports on computer map typing which began with 4th Weather Wing Technical Paper 70-2. The paper uses two methods to analyze in detail the persistency of predetermined surface map types. Using six years of January MSL pressure data for the Colorado map typing window, types were assigned at three hourly intervals. The first method (GO) involves a direct count of consecutive occurrences for each type. To supplement the CONUS map typing program a second method (IO) was used in which a tally was made of consecutive occurrences of types at three and six hours before and after initial time occurrences that were separated by 12 hourly intervals.
