Popis:	The phenologies of autumn and spring migrations by greater snow geese (Anser caerulescens atlantica) are shown to be statistically independent. Spring and fall migration phenologies are demonstrated to be significantly related to synoptic scale atmospheric circulation systems (extratropical storms) rather than a factor such as temperature. Interannual variation in the timing of migratory movements by snow geese reflect interannual variation in the climatology of extratropical storms. Early fall migration is significantly related to an increased frequency of cyclonic disturbances off the United States east and gulf coasts. Years in which autumn migration is delayed occur when the Atlantic coast storm track is displaced northward. Late spring migrations are related to extratropical storms being more frequent over the Great Plains, along the gulf coast, and over the northern Gulf of Mexico. Increased cyclone activity through the Ohio River valley and over the Great Lakes tends to advance the onset of spring migrations.
