註釋"Dates of major spring migration of Lesser Snow and Blue Geese (Anser c. caerulescens) across Winnipeg during 1953 through 1969 were determined and examined in the light of the prevalent weather conditions. Statistically significant correlations between major migration and certain weather factors were established. These results were used as a basis for the design and testing of a simple system for predicting the dates and times of major flights of spring snow goose migration across the Winnipeg Terminal Control Area. The operational feasibility of this migration forecast method for use in air traffic control is discussed"--Abstract.
