Applying a Window Pane Technique to the Colorado Springs Snow Study,
Abstract
The paper supplements 4 WWg Technical Paper 70-5, 'Predicting Heavy Snowfall for Colorado Springs Based on Computer Derived Synoptic Map Types' (AD 718422). The success of the map typing technique described in 4WWTP 70-5 depends upon the size of the area or 'window' selected for typing. In the Colorado Springs snow study the map size chosen covered an area of 10 degrees latitude and 15 degrees longitude. Since this is approximately the size of a synoptic scale disturbance, the map types which were developed gave a good indication of the general circulation pattern required for heavy snow. However, where heavy snowfall is influenced by the local area flow superimposed upon the broader scale features, it is possible that the circulation pattern could correlate highly with a snow type and still not produce the forecast snowfall. The paper describes an attempt to zero-in on the small scale circulation by correlating only one corner of the large window. (Author)
