Abstract : The paper contains the results of applying the weather map typing procedures described in 4 WWg Technical Paper 70-2, Computerized Map Typing Procedures and Their Application in the Development of Forecast Aids, to the specific problem of heavy snow forecasting in Colorado Springs, Colorado. The case study technique described in SECTION IIIA of 4WWTP 70-2 was employed to derive sets of surface and 700 mb map types which are necessary conditions for the occurrence of heavy snow. The objective forecast study technique described in Section IIIB of 4WWTP 70-2 was used to develop a set of forecast aids (scatter diagrams) for each surface/700 mb map type. The snow study described in this paper demonstrates a new approach to objective forecast study development. The synoptic situation has been objectively integrated into the initial stratification of climatological data and therefore permits an objective consideration of surface and 700 mb map patterns as the initial step in the forecast procedure. The inclusion of climatologically-derived map types in the forecast study also allows an excellent means of incorporating prognostic chart information. (Author)
